:MEASure:EGPRs[:CONTinuous]:RFTX:ERMS
Syntax
:MEASure:EGPRs[:CONTinuous]:RFTX:ERMS
Parameters
There are no parameters.
Description
Starts a continuous measurement of the error vector magnitude rms-averaged over a burst. EVM is a relative value
and shown as a percentage. To read out the measurement results, use the :FETCh:EGPRs:RFTX:ERMS command.
Query
The query form of this command starts the measurement and returns a measurement result value as soon as the first
measurement has been completed. The string delivered back contains one floating point real number with the
physical dimension of %.
Example
:MEAS:EGPRs:RFTX:ERMS
:FETC:EGPRs:RFTX:ERMS?
The error vector magnitude rms-averaged measurement is performed. The measurement result is stored internally
and read by the FETC command. An example of the string returned is: "2.33".
:MEASure:EGPRs[:CONTinuous]:RFTX:EPEAk
Syntax
:MEASure:EGPRs[:CONTinuous]:RFTX:EPEAk
Parameters
There are no parameters.
Description
Starts a continuous measurement of the maximum error vector magnitude within a burst. EVM is indicated per cent.
To read out the measurement results, use the :FETCh:EGPRs:RFTX:EPEAk command.
Query
The query form of this command starts the measurement and returns a measurement result value as soon as the first
measurement has been completed. The string delivered back contains one floating point real number with the
physical dimension of %.
Example
:MEAS:EGPRs:RFTX:EPEAk?
The maximum error vector magnitude measurement is performed and the result is returned. Example of the returned
string: "6.33".
