Terms Used in This 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.
State Saved: 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
Preset
.
Dependencies/
Couplings: Describes dependencies or interactions to other functions or settings in the
analyzer.
Power On Last State or User
Factory Preset: Describes the function settings after a
Factory Preset.
Default
Terminator: 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).
Range: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.
History:Describes the firmware revision history. Only applies after first firmware
release.
Remote
Command: Shows the syntax requirements for each SCPI command.
Example: Provides command examples using the indicated remote command syntax.

Measure Commands:
: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 2-1.
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>?.

Configure Commands:
: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.
Fetch Commands:
: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.
INITiate Commands:
: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
One-Button Measurement Functions
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.

READ Commands:
:READ:<measurement>[n]?
• Does not preset the measurement to the factory default settings. For example, if you have
previously initiated the ACP measurement and you send READ:ACP? it will initiate a new
measurement using the same instrument settings.
• Initiates the measurement and puts valid data into the output buffer. If a measurement other
than the current one is specified, the instrument will switch to that measurement before it
initiates the measurement and returns results.
For example, suppose you have previously initiated the ACP measurement, but now you are
running the channel power measurement. Then you send READ:ACP? It will change from
channel power back to ACP and, using the previous ACP settings, will initiate the
measurement and return results.
• Blocks other SCPI communication, waiting until the measurement is complete before
returning the results
If the optional [n] value is not included, or is set to 1, the scalar measurement results
will be returned. If the [n] value is set to a value other than 1, the selected trace data

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:
RBWk span()n⁄=
Where k is a value between 1.2 and 4.0 and n is the number of trace points.
NOTEBecause of the noise-like nature of the signals being measured, the video

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.

Power and Power Spectral Density.

2.2.5Occupied 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 displayed.
For more information see “Meas Setup (Occupied Bandwidth—OBW)” on page 169.
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 (f

2.2.6Adjacent Channel Power—ACP
Adjacent Channel Power (ACP) is a measure of the power that leaks into adjacent transmit
channels. Depending on the radio standard selected from the Mode Setup menu, this
measurement can run in several different modes in order to measure different types of
signals. For more information see “Meas Setup (Adjacent Channel Power—ACP)” on
page 83.
ACP measures the power present in adjacent transmit channels. The span is set according
to the six available offsets and their associated integration bandwidths defined by you or
the selected radio standard (

2.2.9Harmonic Distortion
The range table state determines which harmonics are to be measured. If Range Table is set
Off, for each harmonic to be measured, the center frequency will be set to the
to
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.
One-Button Measurement Functions
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 Num ber 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.
Refer to your measurement guide for examples of this measurement and the calculation of
Total Harmonic Distortion.

2.2.10Burst Power
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
When
Meas Setup, Meas Method, Above Threshold Lvl is selected, the “Measured Area” extends

One-Button Measurement Functions
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).

Example: Sending fewer than six parameters to one of these commands will leave
the values of the unspecified offsets unchanged. If you don’t send settings
for all 6 offsets, it will set all the offsets that you specified, then it will set
any remaining offsets to the same setting as the last offset that you sent.
For example, after the above command is sent, sending the command with
only four paramenters (ACP:OFFS:LIST:STAT ON,ON,ON,OFF) will result
in the fifth and sixth offset remaining the same as the previous setting
(OFF).

limitations. The input attenuator setting will not necessarily give the optimum dynamic

Pressing Limit Test turns the testing of the limit line on or off. When Limit Test is set to On,
each offset is compared to its upper and lower offset limit. In those cases where the power
exceeds the limit, a red “F” is placed next to the dBc result to indicate a failure. If there are
any failures, the pass/fail indicator area show “FAIL” in red; if there are none, it shows
“PASS” in green. Any offsets that are in the off state (see “Offset Freq or Edge Freq” on
