[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.
Parameters:
<analyzer freq>: Receive frequency for the burst signals to be measured
(= center frequency in manual operation)
Range: 0 Hz to max. frequency, depending on
instrument model
<rbw>: resolution bandwidth for the measurement
Range: 10 Hz to 10 MHz in steps of 1, 3, 10
<meas time>: Time span during which measurement samples are sampled for
RMS / peak measurement The type of measurement is selected by
<type of meas>.
Range: 1us to 30s
<trigger source>: trigger signal source. Possible settings:
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.
<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. If <trigger source> = EXTernal is selected, the
value entered here is ignored, as in this case the trigger input uses
TTL levels.
Range: 0 – 100PCT (<trigger source> = VIDeo)
<trigger offset>: Offset between the detection of the trigger signal and the start of the
measurement.
Range: 125 ns to 100s
<type of meas>: Determines whether mean power (RMS) or peak power (PEAK) is to
be measured. The detector is selected accordingly.
Possible values:MEAN, PEAK
<# of meas>: Number of individual bursts to be measured.
Range: 1 to 501
