About the User’s and Programmer’s Information
Ter m s Used in Th is Book
There are many terms used throughout this book, for example “active function block,” that
are explained in detail in the Getting Started guide. It is recommended that you read the
Getting Started guide first.
The following terms are used to describe each key. Note that a key description may not use
all the terms.
Sta te Sa ved : Indicates what happens to a particular function when the instrument
state is saved (either to floppy disk or the internal c:\ drive). It also
indicates whether the current settings of the function are maintained if
the instrument is powered on or preset using Power On Last State or User
Preset.
Dep en d en cies/
Cou p lin gs:
Describes dependencies or interactions to other functions or settings in the
analyzer.
F a ctor y P r eset: Describes the function settings after a Factory Preset.
Defa u lt
Ter m in a tor : Indicates the units that will be attached to the numerical value that you
have entered. This default will be used from the front panel, when you
terminate your entry by pressing the Enter key, rather then selecting a
units key. This default will be used remotely when you send the command
without specifying any units after your value(s).
Ra n ge:
Describes the range of the smallest to largest values to which the function
can be set. If you try to set a value below the minimum value, the analyzer
defaults to the minimum value. If you try to set a value above the
maximum value, the analyzer defaults to the maximum value.
Histor y:
Describes the firmware revision history. Only applies after first firmware
release.
Rem ote
Com m a n d :
Shows the syntax requirements for each SCPI command.
Exa m p le:
Provides command examples using the indicated remote command syntax.

Mea su r e Com m a n d s:
:MEASure:<measurement>[n]?
This is a fast single-command way to make a measurement using the factory default
instrument settings. These are the settings and units that conform to the Mode Setup
settings (e.g. radio standard) that you have currently selected.
•
Stops the current measurement (if any) and sets up the instrument for the specified
measurement using the factory defaults
•
•
Initiates the data acquisition for the measurement
Blocks other SCPI communication, waiting until the measurement is complete before
returning results.
•
•
If the function does averaging, it is turned on and the number of averages is set to 10.
After the data is valid it returns the scalar results, or the trace data, for the specified
measurement. The type of data returned may be defined by an [n] value that is sent with the
command.
The scalar measurement results will be returned if the optional [n] value is not included, or is
set to 1. If the [n] value is set to a value other than 1, the selected trace data results will be
returned. See each command for details of what types of scalar results or trace data results
are available.
ASCII is the default format for the data output. Older versions of Spectrum Analysis and
Phase Noise mode measurements only use ASCII.) The binary data formats should be used
for handling large blocks of data since they are smaller and faster than the ASCII format.
Refer to the FORMat:DATA command for more information.
If you need to change some of the measurement parameters from the factory default
settings you can set up the measurement with the CONFigure command. Use the
commands in the SENSe:<measurement> and CALCulate:<measurement> subsystems
to change the settings. Then you can use the READ? command to initiate the
measurement and query the results. See Figure 1.
If you need to repeatedly make a given measurement with settings other than the
factory defaults, you can use the commands in the SENSe:<measurement> and
CALCulate:<measurement> subsystems to set up the measurement. Then use the
READ? command to initiate the measurement and query results.
Measurement settings persist if you initiate a different measurement and then return to
a previous one. Use READ:<measurement>? if you want to use those persistent settings.
If you want to go back to the default settings, use MEASure:<measurement>?.

Con figu r e Com m a n d s:
:CONFigure:<measurement>
This command stops the current measurement (if any) and sets up the instrument for the
specified measurement using the factory default instrument settings. It sets the instrument to
single measurement mode but should not initiate the taking of measurement data unless
INIT:CONTinuous is ON. After you change any measurement settings, the READ command can
be used to initiate a measurement without changing the settings back to their defaults. In
Spectrum Analysis mode the CONFigure command also turns the averaging function on and sets
the number of averages to 10 for all measurements.
The CONFigure? query returns the current measurement name.
F etch Com m a n d s:
:FETCh:<measurement>[n]?
This command puts selected data from the most recent measurement into the output buffer. Use
FETCh if you have already made a good measurement and you want to return several types of
data (different [n] values, e.g. both scalars and trace data) from a single measurement. FETCh
saves you the time of re-making the measurement. You can only FETCh results from the
measurement that is currently active, it will not change to a different measurement.
If you need to get new measurement data, use the READ command, which is equivalent to an
INITiate followed by a FETCh.
The scalar measurement results will be returned if the optional [n] value is not included, or is set
to 1. If the [n] value is set to a value other than 1, the selected trace data results will be returned.
See each command for details of what types of scalar results or trace data results are available.
The binary data formats should be used for handling large blocks of data since they are smaller
and transfer faster then the ASCII format. (FORMat:DATA)
FETCh may be used to return results other than those specified with the original READ
or MEASure command that you sent.
INITia t e Com m a n d s:
:INITiate:<measurement>
This command is not available for measurements in all the instrument modes:
•
Initiates a trigger cycle for the specified measurement, but does not output any data. You
must then use the FETCh<meas> command to return data. If a measurement other than the
current one is specified, the instrument will switch to that measurement and then initiate it.
For example, suppose you have previously initiated the ACP measurement, but now you are
running the channel power measurement. If you send INIT:ACP? it will change from channel
power to ACP and will initiate an ACP measurement.
•
Does not change any of the measurement settings. For example, if you have previously
started the ACP measurement and you send INIT:ACP? it will initiate a new ACP
measurement using the same instrument settings as the last time ACP was run.
•
If your selected measurement is currently active (in the idle state) it triggers the
measurement, assuming the trigger conditions are met. Then it completes one trigger
cycle. Depending upon the measurement and the number of averages, there may be
multiple data acquisitions, with multiple trigger events, for one full trigger cycle. It
also holds off additional commands on GPIB until the acquisition is complete.

You can configure measurement settings by pressing Meas Setup after selecting Channel
Power. You can make a measurement in single or continuous sweep mode. Pressing Meas
Control enables you to pause or restart a measurement, or toggle between continuous and
single measurement. To set Ref Level automatically, use Optimize Ref Level.
The power calculation method used to determine the channel power is a traditional
method known as the integration bandwidth (IBW) method. A swept spectrum is used as
the basis for this calculation. Therefore, it is important to set the resolution bandwidth
correctly before making this measurement using the following formula:
RBW = k(span) ⁄ n
Where k is a value between 1.2 and 4.0 and n is the number of trace points.
NOTE
Because of the noise-like nature of the signals being measured, the video
bandwidth should be ≥ 10 times the resolution bandwidth.

One-Button Measurement Functions
MEASURE (Spectrum Analysis Mode)
When a DVB-T radio standard is selected, this measurement will also compare the input
signal against a pre-defined spectrum mask. The mask amplitudes defined in the DVB-T
specification (ETSI EN 300 744 V1.4.1) range from 0 dB to 100 dB. This is for power
measured in a 4kHz bandwidth therefore an adjustment to these values will need to be
made as the measurement is made in a 7.61MHz bandwidth.
The measurement makes two sweeps, one in a 4kHz bandwidth and one in a 7.61MHz
bandwidth, then computes the difference between the two. This value will be used to
adjust the mask settings. As this value is calculated as part of the measurement setup, it is
expected that the DVB-T signal to be measured will be present prior to the standard being
selected. The mask will be positioned relative to the power measured in the 7.61MHz
bandwidth. The pass/fail indicator will be used to determine if the input signal exceeds the
mask or not.
If the current span setting is narrower than the mask width, the mask will not be
displayed and the message 10191 displayed in error que. Increase the span to at least the
mask width to display the mask. When the mask is not displayed, the pass/fail
functionality will not be executed therefore no pass/fail flag will be displayed.
To ensure accuracy this measurement requires a specific minimum Sweep Point to Span
ratio. This is calculated using; Sweep Points = Span / (Closest Mask Breakpoint / 2), then
rounded off.
For DVB-T measurements using 24 MHz Span, the number of Sweep Points is 2001. If the
Sweep Point to Span ratio is changed to a value less than the value obtained using the
above algorithm, the message 10192 is then displayed, although the measurement is still
made using the new sweep point to span ratio.

2.2.5 Occu p ied BW
Occupied Bandwidth integrates the power of the displayed spectrum and puts markers at
the frequencies between which a selected percentage of the power is contained. The
measurement defaults to 99% of the occupied bandwidth power. The power-bandwidth
routine first computes the combined power of all signal responses contained in the trace.
For 99% occupied power bandwidth, markers are placed at the frequencies on either side of
99% of the power. 1% of the power is evenly distributed outside the markers. The
difference between the marker frequencies is the 99% power bandwidth and is the value
The occupied bandwidth function also indicates the difference between the analyzer center
frequency and the center frequency of the channel. This “Transmit Freq Error” is defined
as the difference between the (f1 + f2)/2 and the tuned center frequency of the signal. See
The occupied bandwidth measurement can be made in single or continuous sweep mode.
The center frequency, reference level, and channel spacing must be set by the user.

2.2.8 P ow er Sta t CCDF
The CCDF measurement is a statistical measurement of a high-level signal or peak power.
It shows in both graphical and tabular form for what percentage of the time a signal
exceeds its average power, and by how much this average is exceeded. For more
NOTE
ESA Only: CCDF measurement requires the installation of Option AYX (fast
time domain sweeps) or Option B7D (Digital Signal Processing with Fast
ADC).
For each single sweep of this measurement, the average power is defined by:
n
⎛
⎜
⎜
⎝
⎞
⎟
Pavg =
(V2 ⁄ Z0) ⁄ n
∑
⎟
⎠
1
where V is the envelope voltage, Z0 is the characteristic impedance, and n is the number of samples (32k
maximum).
Pavg is used as a guideline to define the probability of the samples, which is xdB above the
average power. The number of samples collected per sweep depends upon the sampling
rate and the setting of the measurement interval. Multiple sweeps may be required if the
sample number exceeds the number of samples collected per sweep. The results and the
CCDF curve are updated after each sweep.
NOTE
It is important to set the correct center frequency before initiating this
measurement.

2.2.9 H a r m on ic Distor tion
The range table state determines which harmonics are to be measured. If Range Table is set
to Off, for each harmonic to be measured, the center frequency will be set to the
appropriate integer multiple of the fundamental frequency and a sweep taken. The
amplitude is calculated by averaging the power in the trace and is displayed in the results
table in the results window. The desired Res BW value for each harmonic is calculated by
multiplying the harmonic number with the Res BW of the fundamental. This results in the
smallest Res BW available being used that is greater than or equal to the computed value.
If a Res BW greater than the instrument maximum is calculated then the maximum Res
BW of the instrument is used and an asterisk (*) is displayed after the amplitude result of
the harmonic to indicate that the desired Res BW was not used. The span for each
harmonic is set to zero.
If Range Table is set to On, for each range enabled after the fundamental, the center
frequency will be set to the frequency of each range. If the current span is set to zero, the
amplitude is calculated by averaging the power in the trace and is displayed in the results
table in the results window. If the range has a non-zero span, the amplitude is calculated
by making a band-power measurement over the span and is displayed in the results table
in the results window.
After the specified number of harmonics have been measured and their amplitudes
displayed, the total harmonic distortion is computed and displayed in the left-hand portion
of the window (view is set to Harmonics & THD). If the measurement is in single mode, the
display will remain at the last harmonic setting and the analyzer sweep will be stopped. If

the measurement is in continuous mode, the measurement will continually measure the
amplitude of the fundamental and harmonics.
For averaged measurements, you may specify the number of sweeps over which the
amplitude of each harmonic is measured. This means that if the Avg Number is set to 10, ten
sweeps will be taken and averaged for each harmonic to be measured. The total harmonic
distortion would then be calculated from these averaged amplitude readings. Note that
averaging applies only to the amplitude of the harmonic, and does not affect the frequency
at which the amplitude is measured.

2.2.10 Bu r st P ow er
The burst power measurement is an accurate method of determining the average power for
the specified burst. Burst power measures the average power in zero-span mode for the
captured burst. This measurement is primarily for use with time domain modulated
signals (Bluetooth™, GSM /Edge, and NADC). The burst width, if not user defined, is
determined by finding the peak in the captured data, then searching for the first place that
the trace is higher than the threshold level. This is considered to be the start of the burst.
The stop of the burst is the first position in the trace that falls below the threshold level.
The mean carrier power is calculated based on the burst width and the threshold level.
Refer to the following figure for clarification of these parameters.
The burst power measurement acquires data from the “Measured Area” above when a
radio standard is chosen and when Meas Setup, Meas Method, Measured Burst Width is selected.
When Meas Setup, Meas Method, Above Threshold Lvl is selected, the “Measured Area” extends
the burst width delimiter lines to the start and stop points.
The mean carrier power is calculated by:
1. converting each trace point amplitude from dBm into linear power
2. Adding the above amplitudes together and dividing by the number of points included in
the average.
3. This value is then displayed in logarithmic form (dBm).

Spectrum Emission Mask measurement includes the in-band and out-of-band spurious
emissions. As it applies to W-CDMA (3GPP), this is the power contained in a specified
frequency bandwidth at certain offsets relative to the total carrier power. It may also be
expressed as a ratio of power spectral densities between the carrier and the specified offset
frequency band. For WLAN, the reference power is taken as the peak PSD in the signal,
and all offset results are also the peak PSD in that offset as opposed to the integrated
power.
Offsets that are turned off (inactive) will return -999.0 when their results are queried over

Press Avg Mode to select the type of termination control used for the averaging function as
either Exp or Repeat. This determines the averaging action after the specified number of
measurements (average count) is reached.
•
EXP (Exponential Averaging mode)—When you set Avg Mode to Exp, each successive
data acquisition after the average count is reached is exponentially weighted and
combined with the existing average. Exponential averaging weights new data more
than old data, which facilitates tracking of slow-changing signals. The average will be
displayed at the end of each sweep.

Repeat—When you set Avg Mode to Repeat, after reaching the average count, all
previous result data is cleared and the average count is set back to 1.

Auto — The burst width is automatically calculated based on the threshold level. For
example, if the threshold level is set to 3 dB, the burst width will be the time between
the two 3 dB points. This will update after each sweep, but before any results are
calculated. Since the measurement only measures over the burst width, this will force a
measurement between the 3 dB points.
•
Man — The burst width used for computing the burst power is controlled by either
entering it directly or as a percentage of the measured burst width. In the percentage
case, the burst width is computed just once based on the most recent measured burst

Power Complementary cumulative distribution function (CCDF) curves characterize the
higher-level power of the signal. It provides the distribution of peak-to-average power
ratios versus probability. A CCDF curve is defined by how much time the waveform spends
at or above the specified power level. The percent of time the signal spends at or above this
level defines the probability for that particular power level.

2.13.6.7 Au to F ill Ra n ge Ta ble
Auto Fill Range Table is used to automatically setup the range table based on the current
range center frequency and span. When selected, the current center frequency is taken as
the fundamental and the frequency in range one is set to this value. Each of the
subsequent range center frequency parameters are set to the appropriate integer multiple
of the fundamental frequency. The span for range one is set to that of the current range.
Each of the subsequent range span parameters are set to the appropriate integer multiple
of the fundamental span. This means that if the fundamental range is zero span, all the
ranges will be zero span. If the range span is zero, Res BW, Video BW, and Sweep Time are
set to the current base instrument settings. If the range span is non-zero, Res BW, Video
BW, and Sweep Time for all harmonics are set to the same settings as for the fundamental.
Span is set to zero for all harmonics and the fundamental.

Enables you to set the relationship between the highest signal that can be displayed (the
reference level) and the input attenuation. The relationship applies whenever the
Attenuation is set to Auto. The relationship is that the attenuation is given by reference
level minus the max mixer level. For example, as the reference level changes, the input
attenuator changes to ensure that a signal at the reference level does not exceed the Max
Mixer Lvl setting.
When the TOI measurement is on, this key controls the maximum mixer level,

2.16.3.3 Ref Ca r r ier F r eq
The Ref Carrier Freq setting determines whether the Ref Carrier Freq is calculated based on
the Center frequency (Auto) or the Center frequency is calculated based on the Ref Carrier
Freq (Man). The Ref Carrier Freq value will always be updated if the Ref Carrier Freq
setting is changed, whether the Mode is set to Auto or Man.
If Ref Carrier Freq is set to auto, it is assumed that the carriers are distributed evenly
around the current center frequency. In this case the following three steps are used to
calculate the Ref Carrier Freq value and the calculated Ref Carrier Freq is shown on the
Ref Carrier Freq key:
1. Ref Freq 1 = Cntr Freq − [(Total of all Carrier Widths)/2]
2. Ref Freq 2 = Ref Freq 1+ (Total of all Carrier Widths excluding the Ref Carrier Width)
3. Ref Freq = Ref Freq 2 + [0.5 (Carrier Width of Ref Carrier)]
The Ref Carrier Freq can also be entered by the user. This will set the Ref Carrier Freq to
Man and the Center frequency of the analyzer will be calculated using the following three
steps:
1. Cntr Freq 1 = Ref Freq − [0.5 (Carrier Width of Ref Carrier)]
2. Cntr Freq 2 = Cntr Freq 1 − (Total of all Carrier Widths excluding the Ref Carrier
Width)
3. Cntr Freq = Cntr Freq 2 + [(Total of all Carrier Widths)/2]
The above algorithms ensure that the carrier is centered on the analyzer display.

2.18 Mea s Setu p (Occu p ied Ba n d w id th —OBW)
When Occupied BW has been selected in the Measure menu of the Spectrum Analysis Mode,
this key displays the appropriate measurement setup menu.
The Occupied Bandwidth measurement integrates the power of the displayed spectrum
and puts markers at the frequencies between which a selected percentage of the power is
contained. The measurement defaults to 99% of the occupied bandwidth power. The
power-bandwidth routine first computes the combined power of all signal responses
contained in the trace. For 99% occupied power bandwidth, markers are placed at the
frequencies on either side of 99% of the power. 1% of the power is evenly distributed
outside the markers. The difference between the marker frequencies is the 99% power
bandwidth and is the value displayed.
The occupied bandwidth function also indicates the difference between the analyzer center
frequency and the center frequency of the channel, referred to as “Transmit Freq Error.”
The measurement can be made in single or continuous sweep mode. The center frequency,
reference level, and channel spacing must be set by the user.

approximately 2 times the expected occupied bandwidth result.
NOTE
If you have an adjacent channel, you should not set the OBW span to 2X your
occupied bandwidth. The OBW measurement first computes all the power in
the span and then 99% of that. Diamond markers are set around the
bandwidth, and the occupied bandwidth results is displayed in the data
window. If the power of the adjacent channel is included in the calculation for
the 100% power, the OBW result will be too high. The OBW Span should be
set narrow enough to encompass the channel of interest and exclude any
unwanted adjacent channels.

total power between those arrows. Frequencies f1 and f2 are determined as the furthest
frequencies x dB below and above P1, respectively. The emission bandwidth is then

2.19.4.1 Offset
Selects the offset pairs (upper and lower) that the menu keys affect, and displays the
memory selection menu from A to E for ESA, or A to F for PSA (where you can store up to 6
sets of values for Start Freq, Stop Freq, Sweep Time, Res BW, Meas BW, Abs Start, Abs Stop,
and so forth). Press Offset until the letter of the desired offset (A, B, C, D, E, or F) is
underlined. Only one selection at a time is shown on this key label. (For PSA only:) Since
the display can show only five results at one time, the Results Index key allows you to scroll
to the sixth result when all offsets are active.

2.19.4.6 Mea s BW
Enables you to specify the bandwidth to use when measuring the offset. When using the
front panel, only the currently selected offset is affected. All the offsets are affected when
using the remote command. This is the multiplier applied to the resolution bandwidth to
determine the bandwidth to integrate when calculating the power.
Key Path:
Key Notes:
Meas Setup, Offset/Limits
The 3GPP standard allows for the construction of an effective
measurement bandwidth out of a group of narrower resolution
bandwidths. This allowance is a remedy for the potential loss in dynamic
range which can occur when carrier energy leaks into the offset due to the
RBW filter ’s shape factor (nominally 12:1). When the offset’s ratio of start
frequency to the Meas BW is small (approximately 4:1), it is recommended
that you select a small Res BW value (30 kHz) and a large multiplier
(Meas BW=33) in order to increase the dynamic range of the
When setting Meas BW > 1, dynamic range is increased, however
measurement time is also increased since an increased number of sweep
points are required to make the measurement. For Meas BW > 1, consider
this equation for trace points:
Trace points = (Offset Stop Freq - Offset Start Freq)/ (Meas BW/100)
When Meas BW = 1, the number of trace points are set at the value
specified upon entering the measurement.
Dependencies/
Couplings:
This parameter must adhere to the rule: (N x Res BW) ≤ (Stop Freq of the
offset - Start freq of the offset), where N is Meas BW value. If the Res BW
is changed, Meas BW will change to ensure this rule.

displays the highest amplitude within the interval. Peak detection is used for CW
measurements and some pulsed-RF measurements. For swept analysis, peak detection
basically obtains the maximum video signal between the end of the last bucket and the
start of the next one. Gain is increased to compensate for the effects of faster sweep rates,
to keep the displayed value accurate. For FFT analysis, the highest spectral amplitude is
displayed, even if that peak amplitude falls between samples of the spectrum computed in
the FFT process.

2.24.3.13.4 Sa m p le PSA Only: The sample detector displays the instantaneous level of
the signal at the center of the interval (bucket) represented by each trace point.
Sample detection is primarily used to display noise or noise-like signals.
Sample detection is not best for amplitude measurements of CW-like signals for two
reasons. First, the peak response to a signal can occur between samples, so unless the
Span to RBW ratio is lower than usual, the highest sample can be well below the peak
signal amplitude. Second, for the high sweep rates normally used, the peak response of the
RBW filters is up to –0.5 dB. This sweeping error is compensated when using the peak and
normal detectors by changing the overall gain. But the gain is not changed when in the
sample detector, because to do so would cause errors in the response to noise.
When Sample is selected, Sampappears on the left side of the display.
