R&S ESU
1. Setting up the instrument and at the same time querying the result list:
This method ensures the smallest delay between measurement and the output of the measured
values, but requires the control computer to wait actively for the response of the instrument.
2. Setting up the instrument and querying the result list after synchronization to the end of measurement:
With this method the control computer can be used for other activities while the instrument is
performing the measurement at the cost of additional time needed for synchronization via service
request.
[SENSe<1|2>:]MPOWer[:SEQuence] <analyzer freq>,<rbw>,<meas time>,<trigger source>,
<trigger level>,<trigger offset>,<type of meas>,<# of meas>
This command configures the instrument setup for multiple burst power measurement and starts a
measurement sequence. When synchronizing the command with *OPC, a service request is
generated as soon as the defined number of individual measurements (# of meas) is reached.
To reduce the setting time, the setup is performed simultaneously for all selected parameters.
The command in the form of a query makes the instrument settings, performs the defined number of
measurements and outputs the measurement results list.
Parameter: <analyzer freq>
Receive frequency for the burst signals to be measured (= center frequency in
manual operation) The range is 0 Hz to max. frequency, depending on instrument
model
<rbw>
Resolution bandwidth for the measurement
The range is from 10 Hz to 10 MHz in steps of 1, 2, 3, 5, 10 steps.
<meas time>
Time span during which measurement samples are sampled for RMS / peak
measurement The type of measurement is selected by <type of meas>. The range
is from 1 us to 30 s.
<trigger source>
Possible settings of the trigger signal source are:
EXTernal:
The trigger signal is fed from the "Ext. Trigger/Gate" input on the rear of the unit.
VIDeo:
The internal video signal is used as trigger signal.
IFPower:
The internal IF signal with 10 MHz bandwidth is used as the trigger signal.
<trigger level>
Signal level at which the trigger becomes active.
For <trigger source> = VIDeo this is the level of the video signal as a percentage
of the diagram height.
For <trigger source> = IFPower this is the signal level in dBm.
If <trigger source> = EXTernal is selected, the value entered here is ignored, as in
this case the trigger input uses the normal trigger settings made via the TRIG key.
The range for trigger source video is 0 – 100PCT.
The range for trigger source IFPower is -70 dBm to +30 dBm.
