:MEASure:EGPRs[:CONTinuous]:RFTX:ENFTh
Syntax
:MEASure:EGPRs[:CONTinuous]:RFTX:ENFTh
Parameters
There are no parameters.
Description
Starts a continuous measurement of the error vector magnitude that is not exceeded by 95% of the symbols of a
burst. The 95% EVM is shown in %. To read out the measurement results, use the :FETCh:EGPRs:RFTX:ENFTh
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:ENFTh
:FETC:EGPRs:RFTX:ENFTh?
The maximum error vector magnitude measurement is performed. The measurement result is stored internally and
read by the FETC command. An example of the string returned is: "4.33".
:MEASure:EGPRs[:CONTinuous]:RFTX:EOFFset
Syntax
:MEASure:EGPRs[:CONTinuous]:RFTX:EOFFset
Parameters
There are no parameters.
Description
Starts a continuous measurement of the origin offset. The origin offset indicates the accuracy of the i/Q modulators
DC setup; it is usually an undesired leakage produced due to a DC offset in the phones I/Q modulator. It is measured
in dBc. To read out the measurement results, use the :FETCh:EGPRs:RFTX:ENFTh 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 dBc.
Example
:MEAS:EGPRs:FTX:EOFFset?
The maximum error vector magnitude measurement is performed and the result is returned, for example: "1.97".
