FETCh:WQUality
FETCh:WQUality[:ALL]?
Function Queries the waveform quality/code domain power measurements.
Measurement results are returned in the following order: integrity, rho, frequency error, time
error, carrier feedthrough, phase error, magnitude error, and error vector magnitude (EVM).
If the multi-measurement state is on, each result represents the average of a number of
waveform quality/code domain power measurements. Multi-measurement state, by default, is off.
To set up multi-measurements, see “SETup:WQUality:COUNt[:SNUMber]” .
