Chapter 2. Product Overview  
About Bluetooth  
Bluetooth wireless technology will simplify connections between everyday appliances such  
as mobile phones, PCs and PDAs. Bluetooth will not be confined to the office - home  
applications will include portable music players, digital cameras, video recorders and  
children’s toys. In future, Bluetooth technology will be found in the automotive, avionics  
and industrial controls markets. Bluetooth technology will provide individuals with a  
personal networking environment that can be found in public places, such as shopping  
centers, sports stadiums and airports.  
The success of the Bluetooth standard will depend on users of the technology enjoying  
products that are reliable with high-quality connections that can be used “out of the box” to  
provide immediate connectivity.  
The combination of leading-edge RF and protocol technologies, coupled with the  
requirement to get implementation costs down to a few dollars, puts particularly high  
demands on the test department to develop test procedures that are comprehensive in  
terms of both RF and functionality. These tests need to be fast and initiated through a  
simple user interface. The integration of a module into an OEM product will not necessarily  
produce predictable results, and the performance of every item will be different, this  
makes it essential to test to a known set of parameters using an instrument traceable to  
National Standards.  
Anritsu knows the importance of test for RF products. We know that in an OEM production  
environment, the key requirement will be to validate performance in the shortest time.  
Production engineers will need to decide on a subset of the Bluetooth RF test specification  
that is appropriate to their product’s requirements.  
Working with RF, especially RF at over 2 GHz is not easy, but with Anritsu as your test  
partner you can be certain of having the most up-to-date and relevant testing capabilities  
for your Bluetooth products.  
The MT8850A/MT8852A  
Anritsu have developed the MT8850A/MT8852A, a Bluetooth Test Set to test Bluetooth  
modules and Bluetooth products - quickly and at low cost.  
Anritsu has a century of experience in RF technology, and today has a reputation for  
developing solutions to test the newest wired and wireless technologies. Our test and  
measurement products are used by customers in over 100 countries worldwide, and our  
experience in the measurement business is second-to-none.

About Bluetooth  
 
MT8850A / MT8852A Bluetooth Test Set  
Product Overview  
MT8850A/MT8852A Features  
Three test modes  
Standard mode in which the MT8850A/MT8852A uses full Test Mode signalling  
and all the defined test controls to test the EUT in the fastest and most efficient  
way possible.  
Single payload mode in which Test Mode signalling is performed in a very  
restricted manner. The customer can define the packet length, packet payload,  
select loopback or TX mode and hopping on or off.  
Null packet mode enables measurements to be made on EUTs that do not have  
test mode support, by performing a limited subset of measurements on packets  
without payloads. None of these measurements are performed in accordance  
with the Bluetooth test specifications.  
Fast  
Keep your production lines flowing with the rapid “Quick Test” measurement script.  
Production test scripts can run in as little as 10 seconds, measuring power, frequency,  
modulation and receiver sensitivity (BER).  
One touch testing  
Once the MT8850A/MT8852A has been configured, each device is tested with a  
single keystroke. Press Run to initiate a link, activate Test Mode, perform the  
measurements and report the results.  
Authoritative  
Under standard operation, tests are made exactly as defined in the Bluetooth RF Test  
Specification. All measurements are traceable to National Standards so that you can  
be totally confident in both your production testing and design proving.  
Reference Bluetooth transceiver  
A custom design transceiver offers <1 kHz frequency accuracy at the start of any  
packet and full compliance with the requirements for the “Dirty Transmitter” for true  
receiver sensitivity measurements. In addition to the standard dirty transmitter table,  
you can define customized stress conditions with user settable values of Carrier  
Frequency Offset, Modulation Index, Symbol Timing Error and simulated carrier  
frequency drift.  
Remote control  
Both GPIB and RS232 interfaces are offered as standard. Creating test programs has  
been simplified by the ability to send single commands for initiating a test and  
returning all results in a single string.  
Small size and weight  
MT8850A/MT8852A takes up minimal space in your test system thanks to its half rack  
size and low weight. Where Bluetooth interfaces are being introduced into existing  
products, the disturbance to the test system is minimized.

Product Overview  
MT8850A / MT8852A Bluetooth Test Set  
Editing tests  
Define your own test scripts to customize the test measurements to your specific  
requirements. Each test can be enabled or disabled and within any test, parameters  
such as hopping can be enabled or disabled, the number of measured packets  
defined, and the specific frequencies of testing set up.  
Making a link  
The BT address can be acquired by entering it manually at the keyboard, by  
performing an inquiry, or by means of an RS232 or USB HCI link. Once the EUT BT  
address is known a Bluetooth link is established using Paging.  
Field upgradeable  
The Bluetooth protocol stack is held in FPGA so that future versions of the core  
Bluetooth specification can be installed locally. The instruments main program is held  
in flash memory and so product enhancements are also field downloadable.  
Design proving  
Because measurements are made in accordance with the RF Test Specification,  
MT8850A/MT8852A is the ideal instrument for pre-conformance testing and design  
proving. Gain confidence in your product before submitting to a Bluetooth Qualification  
Test Facility for approval. To perform tests such as TX output spectrum and spurious  
emissions not supported by the MT8852A, use the Anritsu ME7865A Bluetooth Pre  
Qualification Test System that addresses all 16 test cases defined in the RF test  
specification.  
Audio testing (MT8852A only)  
The MT8852A Bluetooth Test Set can be used to perform audio measurements by  
establishing a Synchronous Connection Oriented (SCO) link between the MT8852A  
and the EUT.  
BlueSuite Analysis Software  
A BlueSuite software package gives PC control of the MT8850A/MT8852A for advanced  
design proving measurements on Bluetooth radios. Use BlueSuite to view burst power  
profiles, modulation eye diagrams, display graphs of the output power of the 79  
frequencies and many other advanced diagnostic tools.

Introduction  
This chapter provides information for the initial inspection and preparation for use of the  
MT8850A/MT8852A Bluetooth Test Set. Shipping and storage information is also  
included.  
Initial Inspection  
Inspect the shipping container for damage. If the container or cushioning material is  
damaged, retain until the contents of the shipment have been checked against the packing  
list and the instrument has been checked for mechanical and electrical operation.  
If the Test Set is damaged mechanically, notify your local sales representative or Anritsu  
Customer Service Center. If either the shipping container is damaged or the cushioning  
material shows signs of stress, notify the carrier as well as Anritsu. Retain the shipping  
materials for the carrier's inspection.  
Power Requirements  
The MT8850A/MT8852A Bluetooth Test Set is operated from AC line power. The  
MT8850A/MT8852A is intended as an Installation (Overvoltage) Category II, Insulation  
Category I device.  
At power-on, the instrument will perform a brief power-on self test (POST). If a POST error  
occurs, information and available options will be displayed on the screen. If the POST is  
successful, the instrument will then go to the top-level script or single test screen that was  
active when it was powered down.  
AC Line Power  
The MT8850A/MT8852A can operate on AC input power of 85-264V, 47-63 Hz, 150 VA  
maximum. The Test Set automatically configures itself for the voltage applied. An internal  
fuse protects the AC line input.  
Fuse Protection  
The MT8850A/MT8852A Bluetooth Test Set is protected on the AC input by an internally  
mounted fuse. Only qualified service personnel should change this fuse. Replace only with  
a fuse of the same type and rating, which is 5 mm x 20 mm, 250V, 2.5A T (T= time lag or  
slo-blo).  
Grounding  
The MT8850A/MT8852A Bluetooth Test Set must be properly grounded. Failure to ground  
the instrument could be hazardous to operating personnel. The instrument is supplied with  
a three-wire power cord.  
The instrument is properly grounded when the plug is correctly installed in a grounded  
receptacle. A grounding terminal is provided on the instrument rear panel.

Power-On Procedure  
 
MT8850A / MT8852A Bluetooth Test Set  
Front Panel Operation  
The Config button allows you to configure the MT8850A/MT8852A  
parameters. The parameters and the procedures are described in the  
"Configuring the MT8852A" chapter.  
The Preset key presets the instrument to a predefined state. See  
Appendix B - Preset Values for details.  
The Clear key is used when you want to clear the last character  
entered or when you want to abort from various functions.  
The Select key is used to select or enter your chosen function.  
The Back key when selected takes you to the previous screen or  
moves you back one level.  
Soft Keys  
There are four soft key positions on the bottom line of the LCD.  
The text corresponding to a soft key appears only when that soft key function is  
active. These keys perform two distinct functions:  
1. To directly access another menu or additional screen. In this case it is used as  
a navigation key.  
2. To initiate an action “Enter”, for example.  
Choosing Screen Entries  
The four arrow keys on the keypad can be used to move the cursors to the screen entry  
that you want choose or edit.  
Cursors  
For each press the cursors will move in the chosen direction. For vertical movement, when  
the cursors reaches the top or the bottom, they will start again at the opposite end.  
When the cursor is at the item that you want to choose or modify, press the  
key.

Running a Single Test  
MT8850A / MT8852A Bluetooth Test Set  
Getting Started  
Running a Script in Standard Mode  
In Standard mode, the MT8850A/MT8852A uses full Test Mode signalling and all the  
defined test controls to test the EUT in the fastest and most efficient way possible.  
Standard mode is the default mode setting, although it should be noted that for devices  
with only a limited implementation of test mode functionality, operation in standard mode  
may result in the EUT dropping the link or failing to respond to commands from the  
MT8850A/MT8852A. In this case, select single payload or null packet operation.  
Running a Script in Single Payload Mode  
Single payload mode uses Test Mode signalling but in a very restricted manner. This is  
ideal when the test device does not yet have a full Test Mode implemented, and the  
repetitive signalling in standard mode may cause it to fail or drop the link. When the user  
selects to run a script in single payload mode, a message to this effect displays on the  
uppermost line of every page to remind the user that a mode other than standard is  
currently selected.  
In this mode, the user can define the packet length, packet payload, and set loopback or  
TX mode and hopping to on or off. The MT8850A/MT8852A then sends a single test  
control to put the EUT into the specified state, and no further test controls are sent. When  
the customer views the measurement screens, only measurements that can be made on  
the selected packets are presented.  
If single payload mode is selected, an additional “single payload edit” line displays on the  
screen.  
1. Move the cursor to the word “Edit” and press the  
key. The user now has two  
pages of configuration for the single payload of their choice.  
2. When the payload selection is complete press  
to return to the main  
measurement screen. Only measurements supported by the selected payload are  
available. Invalid measurements have oval symbols beside them.  
The table below shows the single payload settings required to enable each of the tests.

The four parameters above (“Test control”, “Payload”, “Packet type”, and “Hopping mode”)  
are accessed in the following manner.  
11. Press the  
hard key.  
12. Move the cursor to the script number and press the [Setup] softkey.  
13. Move the cursor to “Edit” and press  
.
14. Make the required settings for “Test control”, “Payload”, and “Packet type”.  
15. Press [1 of 2] softkey to display the second page and make the settings for  
“Hopping”.  
Running a Script in Null Packets Mode  
This mode is used to enable indicative measurements to be made on EUTs that have no  
test mode support. In this mode the MT8850A/MT8852A does not use Test Mode  
signalling at all, and makes only a limited subset of measurements on packets without  
payloads. Measurements are not performed in accordance with the Bluetooth test  
specification. When the user selects to run a script in null packets mode, a message to  
this effect displays on the uppermost line of every page to remind the user that a mode  
other than standard is currently selected.  
The MT8850A/MT8852A can be made to link to an EUT and maintain the link by sending  
POLL packets. In response to a POLL packet, the EUT will return a NULL packet. A NULL  
Packet has no payload but can be used for power, initial frequency, drift, and modulation  
measurements without having to activate test mode.

MT8850A / MT8852A Bluetooth Test Set  
Setting Up Authentication  
Authentication is the process of configuring a Bluetooth unit to connect only to one  
specified device. A headset, for example, can be configured to connect only to a specific  
mobile phone, and in this case, verification processing is used to ensure that the correct  
connections have been established. The MT8850A/MT8852A can be configured to use  
authentication during the establishment of a connection.  
Note:  
The MT8850A/MT8852A does not use authentication by default.  
The process of authentication involves creating a common key, referred to as the link key,  
between the master and slave devices. Security could be compromised if this link key  
were sent between devices, so instead, it is generated from a random number and a  
Personal Identification Number (PIN) which can be entered into the MT8850A/MT8852A.  
If authentication is required but the Bluetooth devices do not have a common link key, the  
authentication procedure is completed using the PIN input, and a link key is then created  
and stored during the authentication procedure. The link key stored in the Bluetooth  
device can then be used during any future connection. Follow the procedure below to  
configure the MT8850A/MT8852A to use authentication.  
1. Press the  
hard key.  
2. Choose “Equipment Under Test (EUT)”.  
3. Press the  
key.

11. Enter the required alphanumeric value, dependant upon PIN length and press the  
“Enter” soft key. The MT8850A/MT8852A will use this PIN key during all subsequent  
connections to any EUT.

Test control delay  
The Test Control delay value can be between 0 and 100. When the MT8850A/MT8852A  
sends a Test Control command (Loopback, TX or Test Pause) the EUT may require a  
period of time to respond before it has actioned the Test Control. This time will vary  
between differing Bluetooth developers implementations. Test control delay causes the  
MT8850A/MT8852A to pause from measuring returned packets until the EUT has had  
time to respond. The number entered is the number of transmitted packets from the  
MT8850A/MT8852A that are ignored before measurements are started.  
Test Pause Test Control  
The Test Pause test control is defined in the Bluetooth specification to improve the  
efficiency of device testing. If an EUT does not support test pause, use of test pause can  
de disabled in the following manner.  
1. Move the cursor to “Test Pause” and press the  
Off.  
key to change the setting to  
EUT Settings on Connection  
The two settings on the screen above that appear below test pause are set by default to  
“ON” and should be left at this setting unless required as detailed below.  
When the MT8850A/MT8852A connects with an EUT it is required by the specification that  
the power be set to maximum. However, as it has been found that this requirement may  
pose a problem for certain EUTs in development, it is now possible to set “Set EUT max  
pwr on connection” to “OFF”.  
In a similar manner to the setting above, it is also possible to set “Read EUT name on  
connection” to “OFF”. Under normal circumstances, the user-friendly name is read when  
a connection is established. However, for certain EUTs still in development, this may  
result in a dropped link, and for this reason it can be set to “OFF”.

Testing in Standard Script Mode  
Individual tests can be tailored to suit requirements. The setup procedures and limits are  
described on the following pages:  
Output Power Test (Standard Mode)  
The output power test performs power measurements on the EUT transmitted packets in  
one of four ways.  
With “Hopping On” mode set to “Defined” the MT8850A/MT8852A measures power only  
when the link hops to one of the frequencies defined on the LOW, MEDIUM and HIGH set  
up screen. Although the measurements are only made at the defined frequencies, it is still  
a hopping link. The number of packets measured at each frequency is set by the user in  
the “Number of packets” field. This is the test method described in the Bluetooth RF Test  
Specification.  
With “Hopping On” mode set to “All” the MT8850A/MT8852A measures the power at every  
one of the 79 frequencies in the Bluetooth channel structure. The number of packets  
measured at each frequency is set by the user in the “Number of packets” field.  
With “Hopping On” mode set to “Any” the MT8850A/MT8852A measures the power at the  
next frequency that the link hops to after the previous power measurement has been  
completed. The total number of packets measured is set by the user in the “Number of  
packets” field. This is typically the shortest of the three options as there is no requirement  
to measure a large number of packets at specified frequencies.  
The MT8850A/MT8852A can perform the test using either loopback test controls or TX  
test controls. The default form for this test is to use loopback. The following test  
description is described using the default test control.  
The MT8850A/MT8852A transmits a pseudo random data payload (PRBS 9) of the  
longest supported type (DH5, DH3 or DH1) or the selected packet type, to the EUT. The  
EUT loops back the data at its maximum output power and the MT8850A/MT8852A  
measures the received power. This test is performed while hopping, and the test is  
repeated until the requested number of packets has been measured on each of the  
selected frequencies. The LOW, MEDIUM and HIGH frequencies relate to the default  
frequencies specified in the Bluetooth RF test specification. The MT8850A/MT8852A  
allows all these frequencies to be changed from their default values.  
1. Choose Output power from the Script menu.  
2. Press the  
key to select or deselect this test from the script routine.  
If a test is selected, the box will be filled in. If not selected the box will be hollow.

Power Control Test (Standard Mode)  
The power control test performs power measurement cycles on the EUT output, if the EUT  
supports power control, at each of the defined frequencies (LOW, MEDIUM and HIGH).  
This measurement is always performed with hopping off. The MT8850A/MT8852A can  
perform the test using either loopback test control or TX test control. The default form for  
this test is to use loopback. The following test is described using the default test control.  
The MT8850A/MT8852A transmits a DH1 (or the operator selected packet type) packet  
with a pseudo random data payload (PRBS 9). This test is performed with hopping off.  
The LOW, MEDIUM and HIGH frequency sets relate to the default frequencies specified in  
the Bluetooth RF test specification. The MT8850A/MT8852A allows all the frequencies to  
be changed.  
A power measurement cycle sets the EUT output power to its maximum and then steps  
the power down to the minimum power and then up to the maximum again one step at a  
time. For each power step a number of data packets are sent to the EUT and looped back  
to the MT8850A/MT8852A.  
When the test is performed in TX test mode only the TX  
frequency settings are used since both RX and TX frequencies  
must be the same.  
1. Choose “Power control” from the Script menu.

Initial Carrier Test (Standard Mode)  
The initial carrier test performs a frequency accuracy test on a DH1 pseudo random data  
packet. (PRBS 9) This test can be performed using either the loopback test control or the  
TX test control. The default is to use the loopback test control. This test can be made with  
either hopping on or off.  
With hopping off, the MT8850A/MT8852A measures the initial carrier frequency error at  
the three frequencies defined on the LOW, MEDIUM and HIGH set up screen. The  
number of packets measured at each frequency is set by the user in the “Number of  
packets” field. This is the test method described in the Bluetooth RF Test Specification for  
an initial carrier frequency test with hopping off.  
With hopping on, the MT8850A/MT8852A can make the measurement in one of two ways.  
If Hopping On mode is set to “All”, the MT8850A/MT8852A will measure the initial carrier  
frequency at every one of the 79 frequencies in the Bluetooth channel structure. The  
number of packets measured at each frequency is set by the user in the “Number of  
packets” field. This is the test method described in the Bluetooth RF Test Specification for  
an initial carrier frequency test with hopping on.  
If Hopping On mode is set to “Any” the MT8850A/MT8852A measures the power at the  
next frequency that the link hops to after the previous initial carrier frequency  
measurement has been completed. The total number of packets measured is set by the  
user in the “Number of packets” field. This is typically the shortest option as there is no  
requirement to measure a large number of packets at every frequency.  
When the measurement is made using TX mode the MT8850A/MT8852A sets up the EUT  
so that when the EUT is polled it transmits a DH1 packet with a pseudo random payload  
for each of the frequencies selected (LOW, MEDIUM and HIGH). This test can be  
performed with hopping off and on. The LOW, MEDIUM and HIGH frequencies relate to  
the default frequencies specified in the Bluetooth RF test specification. The  
MT8850A/MT8852A allows all the frequencies to be changed. When the test is performed  
in TX test mode EUT transmitter and receiver frequencies must be the same.

Carrier Drift Test (Standard Mode)  
The carrier drift test performs a frequency drift measurement over the length of the packet  
received. The test can be carried out for each of the supported packet types with either  
hopping on or hopping off. This test can be performed using either the loopback test  
control or the TX test control. The default is to use the loopback test control.  
In loopback mode with hopping off, the MT8850A/MT8852A sends DH1, DH3 and DH5  
packets with a 10101010.... payload at each of the frequencies selected (LOW, MEDIUM  
and HIGH). The EUT returns the DH1, DH3 or DH5 packet for measurement. The LOW,  
MEDIUM and HIGH frequencies relate to the default frequencies specified in the Bluetooth  
RF test specification. The number of packets of each length that are measured is set in  
the “Number of packets” field. The MT8850A/MT8852A allows all the frequencies to be  
changed. This is the test method described in the Bluetooth RF Test Specification for a  
carrier frequency drift test with hopping off.  
In loopback mode with hopping on, and hopping on mode set to “All” the  
MT8850A/MT8852A sends DH1, DH3 and DH5 packets with a 10101010 payload. The  
EUT returns the DH1, DH3 or DH5 packet for measurement. The MT8850A/MT8852A will  
measure the carrier frequency drift for each packet length at every one of the 79  
frequencies in the Bluetooth channel structure. The number of packets of each length that  
are measured is set in the “Number of packets” field. This is the test method described in  
the Bluetooth RF Test Specification for a carrier frequency drift test with hopping on.  
In loopback mode with hopping on, and hopping on mode set to “Any” the  
MT8850A/MT8852A sends DH1, DH3 and DH5 packets with a 10101010 payload. The  
EUT returns the DH1, DH3 or DH5 packet for measurement. The MT8850A/MT8852A will  
measure the carrier frequency drift at the next frequency that the link hops to after the  
previous carrier frequency drift measurement has been completed. The number of packets  
of each length that are measured is set in the “Number of packets” field.  
In TX mode with hopping on or off the measurement process is the same as for loopback  
except that the MT8850A/MT8852A does not send full DHX packets but just POLL  
packets. The EUT has been configured by the MT8850A/MT8852A to respond to a POLL  
with the appropriate DHX packet. The EUT must support TX mode part of the Test Mode  
specification for this to work. The test time is much shorter when run using TX mode  
compared with loopback, as the MT8850A/MT8852A does not have to send full packet  
lengths. When the test is performed in TX test mode, EUT transmitter and receiver  
frequencies must be the same. TX mode complies with the Bluetooth RF Test  
Specification for a carrier frequency drift test.

perform the test using either loopback test controls or TX test controls. The default form  
for this test is to use loopback. The following test is described using the default test  
control.  
The MT8850A/MT8852A transmits a number of packets containing the four ones four  
zeros payload (11110000), which are looped back by the EUT. Then packets with the  
alternate ones and zeros (101010101) payload are transmitted and are looped back by the  
EUT. These packets are the longest supported packet type as reported by the EUT during  
link set up (DH1, DH3 or DH5) or the selected packet type.  
This test is performed with hopping off, and the test is repeated until the number of  
packets has been measured on each of the selected frequencies as set in the “Number of  
packets” field. The LOW, MEDIUM and HIGH frequencies relate to the default frequencies  
specified in the Bluetooth RF test specification. The MT8850A/MT8852A allows all the

Carrier Drift Test (Single Payload Mode)  
The carrier drift test performs a frequency drift measurement over the length of the packet  
received. This test can be performed using either the loopback test control or the TX test  
control. The default is to use the loopback test control.  
In loopback mode with hopping off, the MT8850A/MT8852A sends a packet with a  
10101010 and the EUT returns packet for measurement.  
In TX mode with hopping on or off, the measurement process is the same as for loopback  
except that the MT8850A/MT8852A does not send full DHX packets but just POLL  
packets. The EUT has been configured by the MT8850A/MT8852A to respond to a POLL  
with the appropriate DHX packet. The EUT must support TX mode part of the Test Mode  
specification for this to work. The test time is much shorter when run using TX mode  
compared with loopback, as the MT8850A/MT8852A does not have to send full packet  
lengths. When the test is performed in TX test mode, EUT transmitter and receiver  
frequencies must be the same. For this test, the TX and RX frequencies are the same. TX  
mode complies with the Bluetooth RF Test Specification for a carrier frequency drift test.

Chapter 9. Audio Measurements  
(MT8852A only)  
The MT8852A Bluetooth Test Set can be used to perform audio measurements by  
establishing a Synchronous Connection Oriented (SCO) link between the MT8852A and  
the EUT. A SCO link is a full duplex link between a Bluetooth master and slave.  
Note:  
It should be noted that SCO is an optional feature within the Bluetooth  
specification. The MT8852A can be used to establish a SCO link and transmit  
HV packets to, or from, the EUT. To perform audio measurements, an audio  
signal source and audio analyzer are also required (e.g., Keithley 2015).  
There are four basic scenarios in which audio measurements may be made, each of which  
is illustrated and explained in this chapter. The four test scenarios are:  
Testing the EUT’s audio performance using remote loopback on the MT8852A.  
Testing the audio performance of the EUT transmit path.  
Testing the audio performance of the EUT receive path.  
Putting the EUT into remote loopback.  
Testing the EUT’s Audio Performance Using Remote  
Loopback on the MT8852A  
The EUTs audio performance can be tested using the set-up below. The MT8852A is put  
into remote loopback and the audio path tested without passing the signal through the  
MT8852A CODEC. The audio is looped back in the MT8852A baseband and so there is  
no audio distortion introduced by the tester.

indicator at the right of this item becomes solid and, if the EUT supports SCO, the  
indicators on the “SCO channel status” line change to clear squares to reflect this.  
6. If the address source is set to RS232 or USB, it is now necessary to make the EUT  
settings shown in the screen below. Press the [1 of 3] soft key followed by the [2 of  
3] soft key to display the third page.  
Note:  
No settings are required on this screen if the EUT address source is not set  
to RS232 or USB. Skip to step 6 in this procedure if you are not initialising  
the EUT using the MT8852A “EUT Control” interface.  
Input coding format:  
Input data format:  
Select the EUT baseband sample input/output data  
format. There are three possible settings, “Linear”, “A-  
Law”, and “u-Law”.  
Select the EUT baseband sample data format. There are  
three possible settings, “1's”, “2's”, and “sign magnitude”.  
Input sample size:  
Select either an 8 or 16 bit baseband sample size.  
Linear PCM bit Posn:  
Set the EUT Baseband sample offset within the 16 bit  
field. Specify a value within the range of 0 to 7.  
Note:  
When these settings are complete it will not be necessary to repeat this  
procedure until the EUT is changed.  
7. Press [3 of 3] to return to page 1 and press the [TX power] soft key.  
8. Enter the “TX power level” value using the keypad. The audio power level can be set  
to between 0 and -90 dBm.  
Note:  
An ACL connection must be made before an SCO link can be established.  
When a device makes an ACL connection, it reports within its “Supported  
Features” response whether or not it supports SCO connections, and if so,  
which HV packet types it can support. Do not establish a SCO connection at  
this stage.

Testing the Audio Performance of the EUT Receive Path  
The performance of the EUT receiver can be tested in isolation with the set-up shown  
below.  
As a replacement for the external audio IN, it is also possible to use an internally  
generated tone. Use of this tone is ideal for quick tests and as it is generated internally, it  
does not pass through the MT8852A CODEC. The tone is fixed at 1kHz. For  
measurement at other frequencies use of external audio is required.  
Position the signal generator and analyzer as shown in the diagram below.  
Note: Refer to the jack plug diagram on the previous page.  
Follow the procedure for “Testing the EUTs Audio Performance” but set the “SCO  
Loopback” setting to “OFF” (step 8 in the procedure).  
Set the “SCO tone generator” on page 2 of 3 to “ON” or “OFF” as required.

Putting the EUT into Remote Loopback  
It is also possible to put the EUT into remote loopback. The MT8852A will then send and  
receive SCO packets from the EUT. The packets will be looped back digitally in the EUT  
baseband and so will not introduce any distortion from the analogue circuits.  
As with the set-up for testing the performance of the receiver, it is also possible to use an  
internally generated 1 kHz tone. Use of this tone is ideal for quick tests and as it is  
generated internally, it does not pass through the MT8852A CODEC. The tone is fixed at  
1kHz. For measurements at other frequencies use of external audio is required.  
Position the signal generator and analyzer as shown in the diagram below.  
Note: Refer to the jack plug diagram on the previous page.  
Follow the procedure for “Testing the EUTs Audio Performance” and use the HCI  
software on the control PC to set the EUT to remoter loopback. SCO loopback for  
the MT8852A should be set to “OFF” (step 8 in the procedure).  
Set the “SCO tone generator” on page 2 of 3 to “ON” or “OFF” as required.

Appendix A. Top-line Messages  
Introduction  
The top line of LCD is reserved for conveying various types of information to the user. The  
40 characters of this line are formatted as follows:  
The left most 30 characters are reserved for text messages of varying lengths  
with a maximum of 30 characters. All messages are left justified.  
The right most 9 characters are reserved for Icons/characters for specific  
instrument features  
The character is left blank between the message and the icons/characters to  
provide separation for clarity  
Message Types  
Each message type carries a particular kind of information. This consists of the following  
types of information:  
Status  
This indicates the internal state of the instrument such as:  
“Script running”  
“Script completed”  
This may be augmented by Measurement status message if relevant  
such as:  
“No payload detected “  
“Searching for channel”  
These two types of messages, when present, are displayed  
alternately.  
Error  
This can be an internal or operator error  
The cause of operator error, as the name implies, is an incorrect  
operation of the MT8850A/MT8852A, during setup/running of a test  
e.g. setup of out-of-range limit value for the pass/fail test criteria,  
results in the message “ >Error!< out of range value”  
This warns you of:  
Warning  
Abnormal condition such as:  
“Warning: over temperature”.  
Non-standard set up of an instrument such as:  
Null Packets. The icon “!“ indicates this condition  
Conditions outside the control of MT8850A/MT8852A such as:  
“Warning: EUT via RF (0x%x)” (see page Error! Bookmark not  
defined.)  
Information  
Safety  
This provides you with helpful information where relevant. For  
example,  
EUT (equipment under test) address mode: if the manual mode is  
selected following the auto, the unit disconnects from the EUT and the  
following message is displayed:  
“EUT disconnected”  
The safety here refers to the MT8850A/MT8852A safety such as:  
“ SYSTEM SHUTTING DOWN"  
" INTERNAL TEMPERATURE EXCEEDED"

Message Priorities  
1) MESSAGE PRIORITIES  
All status messages are mutually exclusive for example:  
“Making connection”  
“Connection made”  
Script running”  
Depending on the use of instrument, more than one message type can be displayed.  
For example, the messages “Null packets mode” and “Script running” may be displayed  
alternately:  
On loss of connection, “Null packets mode” and “Connection lost” will be displayed:  
Some message such as “>Error! < minimum value is ------“ are displayed for a short period  
(2 seconds).  
The safety message is exception to above set of rules. It has the highest priority, over  
riding any current messages. Example of safety message:

Scripts 1 and 2 are factory set to represent common test  
requirements and cannot be altered by the user. To define your  
own script settings use scripts 3 to 10.  
Authentication failure  
The EUT has requested Authentication from the  
MT8850A/MT8852A in order to complete a connection. Set  
the “Authentication” item under Equipment Under Test to  
“Enabled”.  
Connection ended by  
local host  
The MT8850A/MT8852A ended the connection with the EUT.  
Connection ended, low The reason the EUT ended the connection was reported as  
resource  
due to low resources.  
Connection lost, timed  
out  
The MT8850A/MT8852A has not received any communication  
from the EUT for a defined period of time. The default time is  
10 seconds. It can be set under Config \ MT885XA \ RXTX  
settings “Link timeout”.  
Core busy, try again  
When driving the MT8850A/MT8852A via GPIB using the  
auxiliary command, additional rules have to be applied as  
listed below.  
A. After a CONNECT command, check the connection  
complete bit (CON) of the INS register or the ERRLST output  
for the connection failure, before sending another command.  
B. After the INQUIRY command, check that the inquiry is  
complete using status bit (INQ) of the INS register before  
sending any other commands except INQCANCEL command.

EUT not reached Min  
Power  
The EUT was requested to go to minimum TX power and a  
MIN power LMP has not been received.  
EUT RS232 not  
available  
The MT8850A/MT8852A was requested to update the EUT  
settings via the EUT control RS232 interface when the  
Bluetooth address source was not set to RS232.  
EUT test mode rejected On completion of the ACL connection, the MT8850A/MT8852A  
sends an activate test mode command to the EUT. The EUT  
must have been preconfigured to accept this command. If the  
EUT has not been initialised to go into test mode, this error  
message is shown. Only Null packet mode testing can be  
performed in this condition.  
EUT Unsupported  
feature  
The MT8850A/MT8852A has sent a command to the EUT that  
the EUT cannot support.  
External HCI interface  
The instrument’s Bluetooth core is now driven only by the  
RS232 connection on the MT8850A/MT8852A back panel  
using standard HCI commands.  
Host timeout  
The EUT has not responsed to a connection request before the  
accept connection timer has expired.  
Incorrect packet length The packet received from the EUT is not the full length of a  
standard DH1, DH3 or DH5 packet. It is therefore not suitable  
for measurements.  
Repeated attempts  
The EUT reports that too little time has elapsed since an  
unsuccessful attempted to connect, authenticate or pair.  
Invalid Air code  
When attempting to establish a SCO connection with the EUT,  
the MT8852A air code must correspond to the air code used by  
the EUT. Press Config \ MT8852A \ Audio and set the air code  
format to match that of the EUT, before attempting a SCO  
connection.  
Invalid LMP parameters The EUT rejected the LMP due to the parameters not being  
compatible with its present state.  
Invalid packet type  
Warning message from the measurement processor that the  
packet received was not the type it had been requested to  
measure.  
Invalid Payload  
The payload has been corrupted and cannot be used for  
measurements. Typically this would be an error in the  
10101010 or 11110000 bit structure.

Null packets mode  
The MT8850A/MT8852A is configured to make simple  
measurements on Null packets transmitted by the EUT. To  
return to standard Bluetooth operating modes press Scpt/Test ,  
move the pointer to the script number and press the setup  
softkey. Set “Script mode” to Standard.  
Role change not allowed During the connection process the EUT has attempted to  
become the piconet master. This is not allowed by the  
MT8850A/MT8852A which must always remain the piconet  
master. Reconfigure the EUT such that it does not attempt to  
become a master on connection.  
Signal Over Range  
Signal Under Range  
Single Payload mode  
The EUT power is greater than the input range of the  
MT8850A/MT8852A. The maximum input power for  
measurement is +23dBm.  
The EUT power is below the input range of the  
MT8850A/MT8852A. The minimum input power to maintain a  
link is -55dBm, and for power measurements is –30dBm.  
MT8850A/MT8852A has been configured to test an EUT by  
sending one test control at a time. This limits the speed with  
which a range of measurements can be made, but can improve  
reliability with EUTs that do not yet have a robust  
implementation of test mode signalling. To return to the  
standard Bluetooth operating mode press Scpt/Test, move the  
pointer to the script number and press the setup softkey. Set  
“Script mode” to Standard.

Appendix E. Connector Care and Handling  
Follow the precautions listed below when handling or connecting cables. Complying with  
these precautions will guarantee longer component life and less equipment down time due  
to connector or device failure. Also, such compliance will ensure that  
Beware of destructive pin depth mating connectors  
Destructive pin depth of mating connectors is the major cause of failure in the field. When  
an RF component is mated with a connector having a destructive pin depth, damage will  
usually occur to the RF component connector. A destructive pin depth is one that is too  
long in respect to the reference plane of the connector (see figure below).  
N connector pin depth definition  
The center pin of a precision RF component connector has a precision tolerance. The  
mating connectors of various RF components may not be precision types.  
Consequently, the center pins of these devices may not have the proper pin depth.  
The pin depth of DUT connectors should be measured to assure compatibility before  
attempting to mate them with Power Sensor connectors. An Anritsu Pin Depth Gauge  
or equivalent can be used for this purpose.  
Pin depth gauge  
If the measured connector is out of tolerance in the "+" region, the center pin is too  
long (see Allowable DUT connector pin depth table below). Mating under this  
condition will likely damage the precision RF component connector. If the test device  
connector measures out of tolerance in the "-" region, the center pin is too short. This  
should not cause damage, but it will result in a poor connection and a consequent  
degradation in performance.

Avoid over torquing connectors  
Over torquing connectors is destructive; it may damage the connector center pin. Finger-  
tight is usually sufficient for Type N connectors. Always use a connector torque wrench (8  
inch-pounds) when tightening WSMA, K or V type connectors. Never use pliers to tighten  
connectors.  
Avoid mechanical shock  
Precision connectors are designed to withstand years of normal bench handling. However,  
do not drop or otherwise treat them roughly. Mechanical shock will significantly reduce  
their service life.  
Do not disturb Teflon tuning washers on connector center pins  
The center conductor on many RF component connectors contains a small Teflon washer  
that is located near the point of mating. This washer compensates for minor impedance  
discontinuities at the interface. Do not disturb this washer. The location of the washer is  
critical to the performance of the RF component.  
Cleaning connectors  
The precise geometry that makes possible the RF component's high performance can  
easily be disturbed by dirt and other contamination adhering to the connector interfaces.  
When not in use, keep the connectors covered.  
To clean the connector interfaces, use a clean cotton swab that has been dampened with  
denatured alcohol.  
NOTE: Most cotton swabs are too large to fit in the smaller  
connector types. In these cases, it is necessary to peel off most  
of the cotton and then twist the remaining cotton tight. Be sure  
that the remaining cotton does not get stuck in the connector.  
Cotton swabs of the appropriate size can be purchased through  
a medical laboratory-type supply center.  
The following are some important tips on cleaning connectors:  
Use only denatured alcohol as a cleaning solvent  
Do not use excessive amounts of alcohol as prolonged drying of the connector may be  
required  
Never put lateral pressure on the center pin of the connector  
If installed, do not disturb the Teflon washer on the center conductor pin

Verify that no cotton or other foreign material remains in the connector after cleaning it  
If available, use compressed air to remove foreign particles and to dry the connector  
After cleaning, verify that the center pin has not been bent or damaged.
