:MEASure:WCDMa[:CONTinuous]:RFTX:MODQuality:ERMS
:MEASure:WCDMa[:CONTinuous]:RFTX:MODQuality:EPEAk
:MEASure:WCDMa[:CONTinuous]:RFTX:MODQuality:MRMS
:MEASure:WCDMa[:CONTinuous]:RFTX:MODQuality:MPEAk
Example
:MEAS:WCDM:RFTX:MODQ:ALL?
In this case, all relevant RFTX measurements will be performed in a sequence, e.g.
21.624,72.8,15.335,72.736,6.738,27.512,-6.378,0.961,-
28.251,-43.743
.
Syntax
:MEASure:WCDMa[:CONTinuous]:RFTX:MODQuality:ERMS
Parameters
There are no parameters.
Description

Query
The query form of this command will return a floating point value; the unit is percent.
Example
:MEAS:WCDM:RFTX:MODQ:ERMS?
Returns the measured EVM RMS vector error, e.g. 21.624
.
Syntax
:MEASure:WCDMa[:CONTinuous]:RFTX:MODQuality:EPEAk
Parameters
There are no parameters.
Description
Starts a continuous peak vector error magnitude measurement.
Query
The query form of this command will return a floating point value in percent.
Example
:MEAS:WCDM:RFTX:MODQ:EPEA?
Returns the measured EVM peak vector error, e.g.
72.8.
