Test Set Description  
Test Set Description  
The HP 8517B test set configured with an HP 8510B/C network analyzer  
and an HP 8360 series source, creates a system capable of making  
S-parameter measurements from 45 MHz to 50 GHz. The system is  
particularly suited for making two-port device measurements. You can  
measure all four S-parameters without physically reversing the DUT (device  
under test).  
The system is also designed for making measurements on non-reciprocal  
devices or components like transistors, amplifiers or isolators where S  
measurements are required.  
12  
Two directional couplers are used for signal separation. The configuration is  
illustrated in the following figures:  
• Figure 1-1, “Standard HP 8517B Test Set Block Diagram"  
• Figure 1-2, “Option 004, HP 8517B Test Set Block Diagram"  
• Figure 1-3, “Option 007, HP 8517B Test Set Block Diagram"  
For active-device measurements, two bias tees apply external DC bias to  
both test port center conductors.

Verifying Test Set Operation  
Verifying Test Set Operation  
The test set is designed to operate with an HP 8510C network analyzer. You  
can verify its operation by:  
Table 1-2 Test Set Operation Verification  
Checking System Operation  
Checking Specifications  
Perform a system calibration as described in the HP 8510C Operating and  
Programming Manual. A successful calibration indicates that the system, and  
therefore the test set, are operating properly.  
Specifications for the test set, and the system, can be determined by running  
the specification and performance verification software described in the HP  
8510C On-Site Service Manual, Chapter 8, “Specification and Performance  
Verification”. Additional mechanical specifications and supplemental  
characteristics are in Chapter 4, “Specifications” of this manual.  
Troubleshooting the Test Set  
To troubleshoot the test set, refer to the HP 8510C On-Site Service Manual.  
Use the information in that manual to determine if the test set is at fault. If the  
test set is at fault, refer to Chapter 5, “Troubleshooting the Test Set” in this  
manual to isolate the trouble.

Maintaining Measurement Accuracy  
Maintaining Measurement Accuracy  
Precision measurements rely on a precision calibration of the network  
analyzer. As a general rule, the shorter the time lapse between a calibration  
and a device measurement, the more precise the measurement results will be  
(within the limitations of your system).  
Hewlett-Packard recommends calibrating your system every few hours, or at  
least re-verifying your system’s calibration this frequently. Doing so helps  
retain measurement precision.  
The frequency of calibrations is determined by both the location of the  
system and the ambient temperature stability in its operating area.

Controlling Multiple Test Sets  
HP 851X Series, Option 001 test sets allow an HP 8510C to alternately  
control up to four test sets connected to it. For example:  
• While a measurement is underway on test set number 1 (equipped with  
Option 001), a test device can be connected to test set number 2 (which  
does not need Option 001).  
• When the measurement on test set number 1 is complete, the HP 8510C  
can then control test set number 2.  
In a standard test set, the 20 MHz IF and control signals are applied directly  
to J11 TEST SET INTERCONNECT, which is attached to the HP 8510C.  
Option 001 adds a set of IF switches, control switches, and the J10 TEST  
SET INTERCONNECT attachment. This configuration allows the selection  
of the 20 MHz test set IF signal.  
As shown in Figure 3-3 on page 3-4, test set number 1 can:  
• apply its IF signal to the HP 8510C, or it can  
• switch to pass the IF signal from test set number 2, through J10 TEST  
SET INTERCONNECT, and into the HP 8510C.

Multiple Test-Set Connections  
For dual test-set configurations, set each rear panel address switch on each  
test set to the address shown in Figure 3-3. Refer to Figure 3-4 on page 3-7  
for the configuration of two or more test sets.  
• Use the supplied test set interconnect cable to attach test set number 1,  
J11 to the network analyzer.  
• Use the supplied test set interconnect cable to attach test set number 2,  
J11 to test set number 1, J10.  
You may connect up to four test sets in a series if the total length of all test  
set interconnect cables does not exceed 13 meters (about 40 feet). The last  
test set connected in the chain does not require Option 001.  
If the RF coaxial switch is not incorporated into the system, the RF input to  
the test set must be manually switched to the active test set.  
Initialization at  
Power-Up  
At power-up, configure the IF switches so that only one system test set is  
active. To verify which test set is active, use the following steps:  
1. Verify that all system test set LEDs are lit.  
2. View the network analyzer’s test set address by pressing the  
INSTRUMENT STATE, [LOCAL] key, then press {TEST SET}. The HP-IB  
address of the test set is displayed on the screen.  
The address displayed must match the address of the test set selected. If  
not, enter the correct address using the network analyzer’s key pad.  
3. If an unselected test set’s LEDs are lit, deactivate it. Do this by entering  
its address, pressing [x1], then entering the address of the test set desired,  
followed by [x1].  
Selecting a Test Set  
To select another test set, follow the procedure in Table 3-4 on page 3-6 of  
this chapter.  
HP 8517B S-Parameter Test Set Manual 3-5  
Download from Www.Somanuals.com. All Manuals Search And Download.  
               
Table 3-4 Selecting a Test Set When Multiple Units are Configured  
Test Set IF Switching  
A test set is selected via the built-in capability of the analyzer to generate an addressed  
command to each test set. Each time you change the {HP-IB ADDRESS} {TEST SET}  
function (refer to LOCAL [MENU] in the HP 8510C Operation and Service Manual), the  
network analyzer does the following:  
• switches the IF signal of the previously addressed test set to external  
• switches the IF signal of the newly addressed test set to internal  
• sets the test set’s front panel ACTIVE LED to indicate test-set status  
• applies the active test set’s IF signals directly to J11 TEST SET INTERCONNECT  
• passes the inactive test set’s IF signals at J10 through to J11 and on to the next  
test set or to the network analyzer  
Test Set Addressing  
You can change the test set address via program control, or via the network analyzer front  
panel keys. You must also change the mechanical switches on the test-set’s rear panel.  
Here’s how:  
1. Change the test set address via the network analyzer keys;  
a. On the analyzer’s front panel, press the INSTRUMENT STATE [LOCAL] key, then  
press {TEST SET}. The test set’s address appears on the display.  
b. Using the key pad, enter the desired address for the test set, then press [x1]. The new  
HP-IB address appears on the display.  
2. Change the test set address via the HP-IB command:  
From the controller, enter the HP-IB ADDRESS; command, followed by the  
address value. Refer to the command reference for programming details.  
3. Reset the mechanical switches on the test-set’s rear panel. Set the switches to match the  
new HP-IB address displayed on the network analyzer screen.  
RF Switch Driver Control  
When the {HP-IB ADDRESS} {TEST SET} function is changed, the network analyzer  
generates a code sequence. The code sequence is automatically issued across the  
HP 8510C system bus to the device at the ADDRESS of RF SWITCH .  
In the recommended configuration, the device is an HP 11713A attenuator/switch driver. The  
switch/driver in turn controls one or more coaxial switches. These switches, (shown in a  
Figure 3-3, and Figure 3-4) are used to choose which test set receives the RF output from the  
network analyzer source.  
The exact command issued depends upon the new value of the {HP-IB ADDRESS}  
{TEST SET} value, also shown in shown in a Figure 3-3 and Figure 3-4.

Measurement Calibration  
After selecting the active test set, complete the system calibration procedure  
as usual. When you select a different test set, make sure that you recall the  
cal set that applies to that test set.  
NOTE  
Since the cal-set limited instrument state does not include the number of the  
active test set, a cal set which does not apply to the current test set can be  
turned on without displaying the HP 8510C caution messages. However, this  
causes errors in the data displayed because incorrect error coefficients are  
applied to the measured data.  
For convenience, store a hardware-state file and an instrument-state file for  
each combination of test set to cal set. You may also store your hardware  
state file on a tape or disk for future use.  
To change the configuration, recall the appropriate hardware state file. The  
hardware state file:  
• sets the address of test set  
• issues the RF switch command, then  
• recalls the appropriate instrument state file which  
• recalls the cal set

Measuring High-Power Devices with Option 004  
The HP 8517B, Option 004 test set enables devices with output power up to  
30 dBm (1 watt) to be measured at Port 2, without adding external  
attenuators. Reverse dynamic range (S ) degrades by approximately 3 dB.  
12  
When measuring devices having greater than +17 dBm output power, you  
must use the Port 2 step attenuator to decrease the power to ≤+17 dBm.  
The step attenuator has to be set during calibration for the value needed  
during device measurements. However, this setting may cause inadequate  
power level during calibration. Refer to “Changing Signal Path States After  
System Calibration” on page 3-10 for additional information.  
HP 8517B S-Parameter Test Set Manual 3-9  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Changing Signal Path States After System  
Calibration  
Changing an internal attenuator or any external equipment after completing  
the calibration means the measurement results cannot be specified. You must  
use your own estimation of the potential error contribution due to the  
change.  
For example, when the port attenuation is changed with correction ON, the  
message CAUTION: CORRECTION MAY BE INVALID displays. You must judge  
whether the error is tolerable in the particular application and how to  
compensate for the change.  
The application question is: “Does increasing the signal level during  
calibration improve the calibration enough to risk a possible increase in error  
contributions when you change the setup?”  
The only reason for changing an internal attenuator or external equipment  
between calibrations and measurements is to maximize the signal level  
under both conditions, thus minimizing uncertainty due to noise.  
Many factors enter into a setup-change decision, for example:  
• is it more accurate to calibrate at a low signal level without changing the  
setup, or  
• is it more accurate to change the setup to optimize levels for both the  
calibration and measurement  
Changing attenuators at Port 1 or Port 2 does not change the test set  
mismatch, directivity, or isolation characteristics severely. It does change the  
frequency response magnitude and phase, however. The difference between  
frequency response calibration and measurement can be normalized by using  
HP 8510C trace memories.  
Changing the Test Port  
Attenuators  
If only the attenuators at Port 1 or Port 2 are changed, use the following  
procedure to minimize errors:  
1. Connect a short, or a thru, and set Port 1 and Port 2 attenuators for the  
best IF signal levels during calibration.  
2. Perform the appropriate measurement calibration.  
3. Connect the correct calibration standard, set Port 1 and Port 2  
attenuators to the value required for operating the test device.

If you view the response of a short circuit, notice that:  
• Changing Port 1 attenuator has negligible effect on S marker reading  
11  
• Changing Port 2 attenuator has negligible effect on S marker reading  
22  
This is due to the way the attenuators are paired. Both the reference and the  
test signal are changed by approximately equal amounts.  
When viewing S or S , however, changing Port 1 or Port 2 attenuators  
21  
12  
offsets the marker reading by the difference value between Port 1 attenuator  
and Port 2 attenuator.  
Storing Trace  
Memories  
To compensate for the main frequency response effects due to changing  
the attenuators, use the HP 8510C trace memories and trace mathematics  
function, as explained below:  
1. Connect the thru used for calibration and set the port attenuators to the  
value used for device measurement.  
2. Recheck the user parameter levels, then press PARAMETER [S21].  
3. Press MENUS [DISPLAY], then {DATA AND MEMORIES}.  
Press DISPLAY: {DATA-->MEMORY n} to store the S trace in default trace  
21  
memory 1. This trace represents the frequency response difference  
between the S signal path calibration and the measurement.  
21  
4. Press PARAMETER [S12], then press the following DISPLAY: menu keys:  
{SELECT DEFAULTS}  
{DEFAULT to MEMORY: 2}  
{DATA-->MEMORY 2}  
The S trace is now stored in trace memory 2. This trace is the  
12  
frequency response difference of the S signal path between calibration  
12  
and measurement.  
Viewing Normalized  
Parameters  
Use the traces stored in memory 1 and memory 2 to normalize the corrected  
data to the new levels after the attenuation is changed. The next example  
uses normalization for S or S only. To view the corrected parameters:  
21  
12,  
1. Press MENUS [DISPLAY], then {DATA AND MEMORIES}  
2. Press PARAMETER [S11] and view the S measurement.  
11  
3. Press PARAMETER [S22] and view the S measurement.  
22  
4. Press PARAMETER [S21], then the following DISPLAY: menu keys:  
{SELECT DEFAULTS}  
{DEFAULT to MEMORY: 1}  
{MATH ( / ) }

Download from Www.Somanuals.com. All Manuals Search And Download.  
       
5. View the S measurement. If the thru is connected, the transmission  
21  
coefficient should be 1 ∠0° .  
6. Press PARAMETER [S12], then press the following DISPLAY: menu keys:  
{SELECT DEFAULTS}  
{DEFAULT to MEMORY: 2}  
7. Press PARAMETER [S12] to view the S measurement. If the thru is  
12  
connected, the transmission coefficient should be 1 ∠0° .  
Normalization is turned OFF for S and S measurements. Then the  
11  
22  
appropriate memory is selected and normalization is turned on to view S  
21  
and S .  
12  
Since these are accurate, repeatable attenuators, this sequence may be  
effective in your application. If other parts of the test must be changed,  
especially components connected to the test ports, this procedure may  
require additional steps to adequately compensate for the changes.

Making Operational Checks  
To check the operation of multiple test-set configurations, do the following:  
1. Connect a device with a known response to test set number 1. Press the  
following HP 8510C front-panel keys:  
INSTRUMENT STATE [LOCAL]  
AUXILIARY MENUS [SYSTEM]  
{HP-IB ADDRESSES}  
{TEST SET}  
2. When the message TEST SET HP-IB ADDRESS appears, enter [20], the  
address of test set number 1, then press [x1]. The measurement trace from  
test-set number 1 should display.  
3. Store the trace in memory by pressing the following keys:  
MENU [DISPLAY]  
{DATA AND MEMORIES}  
{DATA --> MEMORY n}  
DISPLAY: {DATA and MEMORY]  
4. Next, enter the HP-IB address of test set number 2, followed by [x1], then  
re-enter the address of test set number 1 followed by [x1].  
5. Repeat the above procedure for each of the other test sets in the system.  
Observe any difference in the response between the stored trace and the  
results trace by switching back and forth between the test sets.  
Any differences in data that you suspect are due to the IF switch (Option  
001) or to RF switching, must be checked out. Refer to Chapter 5,  
“Troubleshooting the Test Set” in this manual.

Using Anti-Rotation Clamps  
During the performance verification procedure, use anti-rotation clamps to  
secure RF connections at the test ports of each test set. While installed, each  
clamp stabilizes the connector on RF cable to the large nut on the test set’s  
RF test port. If an adapter is used, the clamp stabilizes the adapter to the  
front panel RF port connector.  
Without these clamps, the test port connections can loosen when a device  
under test is moved. As a result, the loosening can invalidate calibrations and  
measurements.  
NOTE  
These instructions refer to an installation using HP RF cables. However, the  
anti-rotation clamps may also be used with front panel adapters. Adapter  
installations are similar. There are two anti-rotation clamps included in the  
test set accessories box.  
Attach the first clamp  
Remove one anti-rotation clamp from the accessories box. Loosen its  
thumb-screw until it is nearly freed from the counter-sink socket in the  
clamp body. The clamp is shown as item (5) in Figure 2-1, “Accessories  
Supplied with the HP 8517B Test Set.”  
1. Gently push the clamp (round-hole end first) over and past the RF cable  
connector to be used.  
2. Fit the rubber O-ring in the round end of the clamp over the connector.  
NOTE  
If the O-ring is not snug or is damaged, refer to the Chapter 6, “Replacement  
Procedures” for instructions about replacing the internal O-ring.  
3. Wiggle the clamp to ease it over the connector.  
4. Attach the cable to the test port and tighten it as specified in the cable  
manual.  
NOTE  
Do not twist the cable as you attach it to the test port.  
Use the torque wrench supplied with your calibration kit to tighten the cable  
to 90 N-cm (8 in-lb). Do not over-torque the connection. See Figure 3-5.

Download from Www.Somanuals.com. All Manuals Search And Download.  
       
CAUTION  
Important! The test set RF connector becomes loosened easily. Hold the RF  
cable securely throughout the remainder of this procedure. Do not allow the  
cable to rotate.  
Figure 3-5 Using a Torque Wrench Correctly  
Positioning the thumb-screw  
See Figure 3-6. Position the clamp so the thumb-screw is positioned at the  
top of the clamp.  
• Turn the clamp to visually align the clamp flats with the flats on the test  
port connector nut.  
• This positioning minimizes rotating the connector in the procedure step.

NOTE  
The flats may actually be in any orientation, with respect to the front panel.  
Figure 3-6 Visually Aligning Clamp and Nut Flats  
Positioning the connector  
See Figure 3-7. Maneuver the clamp over the RF connector and onto the test  
port connector.  
1. Hold the test cable with one hand. Use the other hand to press the clamp  
gently and steadily, as you wiggle it into position straight over the RF  
connector and onto the test port connector nut.  
NOTE  
Be sure to loosen the clamp when you are slipping it over the connector.  
2. Fit the internal flats in the clamp over the flats on the test port connector  
nut.  
3. Avoid rotating the clamp as you position it so the RF connection remains  
tight (remember it loosens easily).

Troubleshooting the Test Set  
The troubleshooting strategy for the HP 8517B S-Parameter test set is a  
systematic sequence of procedures. The information may be used after  
system-level troubleshooting has identified the test set as the problem  
instrument.  
Use the troubleshooting flowchart in Figure 5-2 to help isolate the faulty  
assembly. Notice procedure numbers within some of the flow diagram  
blocks. These are keyed to troubleshooting procedures. Perform the  
numbered procedure associated with each block as you progress through the  
chart.  
Refer to the block diagrams, located at the end of this section, to help you  
understand the test set’s operation.

Troubleshooting the Test Set  
Theory of Operation  
Theory of Operation  
RF paths for Port 1 and Port 2 are similar. This section discusses in detail the  
source power signal, as it is routed via the RF IN connector, through the test  
set, and to Port 1 for S and S measurements.  
11  
21  
Figure 5-1 Standard HP 8517B RF Block Diagram  
The RF Source Power  
• RF source power enters the test set through the rear panel. The RF power  
is applied to the switch/splitter (A18).  
• At the switch/splitter, the power is attenuated by approximately 7 to  
14 dB, depending upon frequency.  
• The switch/splitter receives its control signals from the attenuator/switch  
driver board (A5).  
• The switch part of the switch/splitter, which is a combination of two  
power splitters and a solid-state switch, selects the power splitter to use  
and, therefore, the test port to receive the RF power.  
• LEDs on the front panel and on the attenuator/switch driver board (A5)  
indicate which test port is active.

Troubleshooting the Test Set  
Theory of Operation  
The Reference Signal  
Path  
• The reference signal is routed from the switch/splitter through the  
20-7 dB tapered pad (AT1) to attenuate any VTO feed-through signals.  
• The signal is then applied to A10, the a1 sampler assembly, where it is  
down-converted to a 20 MHz IF (intermediate frequency).  
• Because the RF power is being routed to Port 1, the a1 IF signal is used  
to phase lock the network analyzer. Had the RF power been routed to  
Port 2, the a2 IF signal would have been used to phase lock the network  
analyzer.  
The Test Signal Path  
• The test signal is routed from the switch/splitter (A18) to the 60 dB  
programmable attenuator (A16) for Port 1.  
• The signal may then be attenuated in 10 dB steps or passed through  
without attenuation to Port 1 bias tee (A7).  
• A bias supply to provide dc voltage to Port 1 bias tee can be connected  
to J8 on the rear panel of the test set, also.  
• The RF signal rides this dc level which is used to turn active devices on  
(bias ON) so their S-parameters can be measured.  
• Beyond the bias tee, the test signal travels to the directional coupler  
(A6).  
• At the coupler, the incident RF power is applied to the device under test.  
The S and S  
Measurements  
• The signal reflected from the DUT is separated from the signal incident  
11  
21  
to the DUT by the Port 1 coupler (A6).  
• The reflected signal exits the coupler and is applied to b1 sampler (A12),  
then is down-converted to a 20 MHz IF signal.  
• The S measurement is the ratio of the two IF signals from a1 and b1  
11  
samplers.  
• The incident signal is transmitted through the DUT, through Port 2  
coupler, then into b2 sampler (A13).  
• The incident signal is down-converted to a 20 MHz IF so S can be  
21  
measured. S is the ratio of the two IF signals from samplers a1 and b2.  
21  
The Sampler Control  
Switching  
• The samplers may be turned on and off, depending upon the parameter  
being measured.  
• Sampler switching is controlled by a microprocessor on the HP-IB board  
assembly (A4). The default condition (test set power ON and no HP-IB  
commands sent by the network analyzer) is for the test set to be active  
with the RF signal applied to Port 1.

Download from Www.Somanuals.com. All Manuals Search And Download.  
       
Troubleshooting the Test Set  
Theory of Operation  
• If the test set is equipped with Option 001 (multiple test set capability),  
its begin state is inactive. That is, rather than using the test set’s internal  
IF, a switch is set in the test set to accept an IF from another test set.  
The LO Signal Control The LO, generated by A14 VTO/driver, is phase locked to the source so the  
desired VTO harmonic is 20 MHz greater than the source frequency.  
The phase-locked loop includes:  
• Portions of the test set, such as the VTO summing-amp board (A3), the  
VTO/driver (A14), and the a1 sampler assembly (A10), and  
• The HP 8510C Network Analyzer  
The VTO summing-amp board (A3) provides control voltages to tune the  
VTO to the correct LO frequency.  
The VTO also has an output LENDRA (Low END of RAnge) which is  
routed via the test set interconnect cable, to the HP 85102.  
The LENDRA provides an indication to the network analyzer about whether  
or not the VTO is operating within its normal frequency range.  
If the VTO exceeds its normal frequency range, the network analyzer  
displays the running error message VTO OVER RANGE.  
CAUTION  
Electrostatic Discharge Sensitive (ESD) Assemblies  
Assemblies you might handle in these troubleshooting procedures are  
extremely sensitive to damage from static electricity. They may or may not  
continue to function if they are subjected to electrostatic discharge. Their  
reliability, however, will be impaired.

Problems  
Determining the RF component in the test set that is most likely the cause of  
a failure can be accomplished within four steps:  
1. Run the signal-path tests on paths 1 through 6 using the procedures on  
the following pages.  
2. Record your test results in Table 5-6 for each path.  
3. Compare the results in Table 5-6 with those in Table 5-7.  
4. Investigate the most probable cause, based on the information in  
Table 5-7.  
Testing Signal Paths 1-4  
1. Set the network analyzer to its factory default settings by pushing the  
front-panel TEST switch.  
2. Set the source for step mode. Press the network analyzer keys:

HP 8517B Replaceable Parts  
Introduction  
This section provides information about ordering replacement parts. Parts  
that can be replaced include major assemblies and chassis hardware, but not  
individual pieces of major assemblies. Table 7-1 lists the major assembly  
reference designations and abbreviations used in the parts lists.  
Rebuilt-Exchange  
Assemblies  
Rebuilt-exchange assemblies (R-E assemblies) cost less than new  
assemblies. They are available through the rebuilt-exchange program.  
Factory rebuilt (repaired and tested) assemblies meet all factory  
specifications required of a new assembly. They are available on an  
exchange (trade-in) basis only. Defective assemblies must be returned for  
credit. Figure 7-2 illustrates the rebuilt-exchange procedure. The rest of the  
figures in this chapter provide parts information. If you have any questions,  
contact the HP Sales and Service office in your region.  
Replaceable Parts List  
Use the illustrations in this chapter to help locate and identify HP 8517B  
replaceable parts. Each illustration is accompanied by a replaceable parts list  
that includes the following information:  
• Hewlett-Packard part number.  
• Part quantity as shown in the corresponding figure. (There may or may  
not be more of the same part located elsewhere in the instrument.)  
• Part description, using the abbreviations found in Table 7-3.  
NOTE  
A typical manufacturer of the part is identified by a five-digit code (refer to  
the Manufacturers Code list in Table 7-2) and given only if a part is available  
from an alternate supplier (other than Hewlett-Packard).
