:CALCulate:WCDMa:RFTX:MODQuality:ERMS:LIMit[:FAIL]
:CALCulate:WCDMa:RFTX:MODQuality:ERMS:LIMit:STATe
:CALCulate:WCDMa:RFTX:MODQuality:ERMS:LIMit:UPPer:[DATA]
Description
This command switches the check of the measurement result values of all modulation
quality measurement against their user-definable limits either ON or OFF.
Query
There is a query form which returns the stored settings.
Example
:CALC:WCDM:RFTX:MODQ:ALL:LIM:STAT ON
Switches the limit check for all modulation quality measurement on.
Syntax
:CALCulate:WCDMa:RFTX:MODQuality:ERMS:LIMit[:FAIL]?
Parameters
There are no parameters.
Description
There is solely a query form of this command available.
Query
This command delivers a boolean number in a string which indicates if the
:MEAS:WCDMA:ARR:RFTX:MODQ:ERMS measurement violated its limits.
Example
:MEAS:WCDMA:ARR:RFTX:MODQ:ERMS 20
:CALC:WCDM:RFTX:MODQ:ERMS:LIM?
Returns 1 if any of the EVM RMS vector error measurement results was out of limits,
or 0 if none of the results was out of limits.
Syntax
:CALCulate:WCDMa:RFTX:MODQuality:ERMS:LIMit:STATe
<PredefExp>
Parameters
PredefExp may take on one of the following predefined expressions:
ON|OFF.
The default is ON.
Description
This command switches the check of the measurement result values of the EVM RMS
vector error measurement against their user-definable limits either ON or OFF.
Query
There is a query form which returns the stored settings.
Example
:CALC:WCDM:RFTX:MODQ:ERMS:LIM:STAT ON
Switches the limit check for the EVM RMS-averaged vector error measurement on.
Syntax
:CALCulate:WCDMa:RFTX:MODQuality:ERMS:LIMit:UPPer
:[DATA] <Real1>
Parameters
Real1 is a floating point real number. The minimum value for the parameter is 0.0,
the maximum is 200.0, the resolution is 0.1, the default is value is 17.5.
Description
Sets the upper limit for the EVM RMS average vector error. The physical dimension of
the number stated is percentage.
Query
There is a query form which returns the stored settings.
Example
:CALC:WCDM:RFTX:MODQ:ERMS:LIM:UPP 200
:CALC:WCDM:RFTX:MODQ:ERMS:LIM:UPP?
The query returns the previously set value
200.0.
