:READ<ch>[:POWer]?
Triggers power measurement and displays the results. The sensor returns the result in
the unit set with command
Certain power sensors, such as the R&S NRP-Z81, return two values, first the value of
the average level and - separated by a comma - the peak value.
Note:
This command does not affect the local state, i.e. you can get results with local
state on or off. For long measurement times, we recommend that you use an SRQ for
command synchronization (MAV bit).
