:MEASure:WCDMa[:CONTinuous]:RFTX:MODQuality
:IQIMbalance
:MEASure:WCDMa[:CONTinuous]:RFTX:INNErloop
:MEASure:WCDMa:RFTX:OPENloop
:MEASure:WCDMa:RFTX:OPENloop
Example
:MEAS:WCDM:RFTX:MODQ:IQOF?
Returns the origin offset in dBc, e.g. -28.251
.
Syntax
:MEASure:WCDMa[:CONTinuous]:RFTX:MODQuality:IQIMbalance
Parameters
There are no parameters.
Description
Starts a continuous IQ imbalance vector error measurement.
Query
The query form of this command will return a floating point value with the result in
dB.
Example
:MEAS:WCDM:RFTX:MODQ:IQIM?
Returns the IQ imbalance in dBc, e.g.
-43.743.
Syntax
:MEASure:WCDMa[:CONTinuous]:RFTX:INNErloop
Parameters
There are no parameters.
Description
It starts a continuous inner loop power measurement.
Query
The query form of this command will start the measurement and return the results
values as soon as the first measurement has been completed as well the error values.
The result delivered will contain an array of floating point numbers.
Example
:MEASure:WCDMa[:CONTinuous]:RFTX:INNErloop?
Syntax
:MEASure:WCDMa:RFTX:OPENloop
Parameters
There are no parameters.
Description
It starts a single openloop power measurement.
Query
There is no query form of this command available.
Example
:MEASure:WCDMa:RFTX:OPENloop
Starts the open loop power measurement, then a loopback or speechcall has to be
established to measure the PRACH.
:FETC:WCDM:RFTX:OPEN? will deliver the measured value for open loop power.
Syntax
:MEASure:WCDMa:RFTX:OPENloop
Parameters
There are no parameters.
Description
It starts a single open loop power measurement.
