MEASURE (Spectrum Analysis Mode)
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 default s
• 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 param e ters 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 sett ing s other than the
factory defaults, you can use the commands in the SENSe:<measurement> and
CALCulate:<measure m e n t > subsystem s to s e t u p the measure ment. Then use th e
READ? command to initiate the measurement and query results.
Measurement settings persist i f you initiate a different measure ment and then ret urn 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>?.

MEASURE (Spectrum Analysis Mode)
Configure Commands:
:CONFigure :<mea sur emen t>
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 Anal ysis mode th e CONF ig ure co mman d al so t urns t he a ve ragin g fu ncti on o n and set s
the number of averages to 10 for all measurements.
In instruments with firmware older then A.05.00 CONFigure initiates the taking of data. The
data should be ignored. Other SCPI commands can be processed immediately after sending
CONFigure. You do not need to wait for the CONF command to complete this ’false’ data
acquisition.
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 mea surement. You can only FETCh results from the
measurement that is currently active, it will not change to a different measurement. An error is
reported if a measurement other than the current one, is specified.
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 tho se specified wit h the original READ
or MEASure command that you sent.
One-Button Measurement Functions

MEASURE (Spectrum Analysis Mode)
INITiate Commands:
:INITiate:< measur ement>
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 initi at ed 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 mea surement setti ngs. For example, if you have previ ously start ed
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 st ate) it triggers the
measurement, assuming the t rigger condit ions are met. The n it complete s 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 da ta int o the output buffer. If a measurement other
than the current one is specified, the instrument will switch to that measurement befor e it
initiates the mea sur e men t and re tur ns re s ults.
For example, suppose you have previously initi at ed 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 meas urement resu lts
will be returned. If the [n] va lue is s et to a value o ther than 1, the selec ted trace d ata
results will be returned. See each command f or detail s of what types of scalar res ults
or trace data results are available. The binary data formats should be used when
handling large blocks of data since they are smaller and faster then the ASCII
format. (FORMat:DATA)

Meas Setup after selecting Channel
The power calculation method used to determine the channel power is a traditional
method known as the integration bandwidth (IBW) met hod. 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
bandwidth should be ≥ 10 times the resolution bandwidth.

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 p resent prior to the standar d being
selected. The m a sk w i l l b e positioned re l a ti v e to th e power meas u r e d in th e 7.61MHz
bandwidth. The pass/fail indicat or will be us ed to deter mine if the inp ut signal exceed s 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. 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 Swe ep Point to Span
ratio. This is calculate d 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.

2.2.4Occupied 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 de faults to 99% of the oc cupied bandwid th po we r. The power-bandwidth
routine first computes the combined power of all signal respons es 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 outsid e the mar kers. The
differenc e be tween the ma rker freque n cies is the 99% power band w i dth and is th e v a l u e

Pavg is used as a guideline to def ine 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 inte rv al. 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.
Results from a 2.17 GHz 3GPP W-CDMA input signal are shown below in Figure 2-4 .

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 a v eraging the power in the trace and is d isp layed 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 fundament al. This r esults 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 maxim um Res
BW of the instrument is used and an asterisk (*) is displayed after the amplitude result of
the harmonic to indicate that the desi red 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 a v eraging the power in the trace and is d isp layed 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 result s w i n d o w.

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 whi ch the
amplitude of each harmonic is measured. This means t hat 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 aff ect the frequency
at which the amplitude is measured.

2.2.9Burst Power
The burst power measurement i s an accurate method of deter mining the a verage power for
the specified burst. Bur s t power measures the avera g e po w er in zero-sp a n m o de for the
captured burst. This measurement is primarily for use with time domain modul ated
signals (Bluetooth™, GSM /Edge, and NADC). The burst width, if not user defined, is
determined by finding the pea k in the captured d ata, then searc hing for the firs t 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

and all offset results are also the peak PSD in that offset as opposed to the integrated
power.

Fast method is selected,
the 5 point ACLR measurement method is used. The following parameters are configured
to allow the measurement to be made. This method is only available for the 3GPP
W-CDMA radio standard, this key will be disabled for all other radio standards.
NOTEThe current function values are not saved when fa st method is turned on.
Most functions are disabled when Fast is selected.

2.3.8Total Pwr Ref
Enables you to set the adjacent channel power reference to automatic or manual when
Meas Type is set to Total Pwr Ref. When set to automatic, the carrier power result reflects
the measured power value in the carrier. When set to manual, the last measured value is
captured and held, or may be entered by the user. Relative values are displayed,
referenced to the total power measured in the main channel.

2.3.10Limit Test
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 indicat e 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
page 83) are not measured and their results will not be displayed on screen.
