BB:MEAS:POW:RMS
Queries the rms level of the baseband signal.
Example:
Query onlyUsage:
[:SOURce<hw>]:BB:MEASurement:RTIMe?
This command indicates the remaining time until the measurement of the digital I/Q
baseband signal is completed. The time is displayed in format "hh:mm:ss".
Return values:
string
hh:mm:ss
<Rtime>
Default unit:
BB:MEAS:RTIM
Queries the remaining measurement duration.
Example:
Query onlyUsage:
[:SOURce<hw>]:BB:MEASurement:SOURce <Source>
This command selects the signal source for the measurement. The signal level and crest
factor can be retrieved either from the interference-free digital I/Q baseband signal or the
signal superimposed by the noise generator AWGN.
Parameters:
BB|BAWGn
