performs the same measurement and returns the result list immediately after the last frequency point.
•
The measurement is performed in the time domain and therefore the span is set
to 0 Hz. If the time domain is abandoned, the function is automatically switched
off.
•
The measurement is not compatible with other measurements, especially as far
as marker, adjacent channel power measurement or statistics are concerned.
The corresponding commands thus automatically deactivate the function.
•
The function is only available in remote control. It is deactivated when switching
the instrument back to LOCAL.

[SENSe<1|2>:]LIST:POWer:SET <PEAK meas>,<RMS meas>,<AVG meas>,<trigger mode>,<trigger
slope>,<trigger offset>, <gate length>
This command defines the constant settings for the list during multiple power measurement.
Parameters <PEAK meas>, <RMS meas> and <AVG meas> define, which measurements are to be
performed at the same time at the frequency point. Correspondingly, one, two or three results per
frequency point are returned for the SENS:LIST:POW? command. If all three parameters are set to
OFF, the command generates an execution error.
Parameter:
<PEAK meas>: ON activates the measurement of the peak power (peak detector).
OFF deactivates the measurement of the peak power.
<RMS meas>: ON activates the measurement of the RMS power (RMS detector).
OFF deactivates the measurement of the RMS power.
<AVG meas>: ON activates the measurement of the average power (average
detector). OFF deactivates the measurement of the average power.
<trigger mode>: Selection of the trigger source used for the list measurement.
Possible values: IMMediate | VIDeo | EXTernal | IFPower
<trigger slope>: Used trigger slope.
Possible values: POSitive | NEGative
<trigger offset>: Offset between the detection of the trigger signal and the start of
the measurement at the next frequency point.
Range of values: 0 s, 125 ns to 100s
