SENSe:MPOWer Subsystem
The commands of this subsystem are used to determine the mean burst power or peak burst power for
a given number of signal bursts, and for outputting the results in a list. Since all the settings required for
a measurement are combined in a single command, the measurement speed is considerably higher
than when using individual commands.
For measuring the signal bursts, the gated sweep function is used in zero span. The gate is controlled
either by an external trigger signal or by the video signal. An individual trigger event is required for each
burst to be measured. If an external trigger signal is used, the threshold is fixed to TTL level, while with
a video signal the threshold can be set as desired.

Depending on the settings made, the measurements are performed with the RMS detector for RMS
power or the PEAK detector for peak power. For all these measurements, trace 1 of the selected
system is used.
The setting parameters for this measurement are:
• analyzer frequency
• resolution bandwidth
• measurement time used for a single burst
