:MEAS:WCDMA[:CONTinuous]:RFSPectrum:ACLR
Syntax
:MEASure:WCDMa[:CONTinuous]:RFSPectrum:MSPectrum[:DATa]
Parameters
There are no parameters.
Description
Starts a continuous measurement of the RF modulation spectrum. To read out the
latest measurement result, use the FETC:WCDM:RFSP:MSP[:DATA] command.
Query
This query command will start the measurement and return a result value as soon as
the first measurement has been completed. The result delivered will contain an array
of 501 floating point numbers.
Example
:MEAS:WCDM:RFSP:MSP?
Syntax
:MEASure:WCDMa[:CONTinuous]:RFSPectrum:MSPectrum:AVG
<Int1>
Parameters
There are no parameters.
Description
Starts a continuous measurement of the RF modulation spectrum averaged over
<Int1> measurements. To read out the latest measurement result use the
FETC:WCDM:RFSP:MSP:AVG command.
Query
This query command will start the measurement and return a result value as soon as
<Int1> measurements have been completed. The result delivered will contain an
array of 501 floating point numbers.
Example
:MEAS:WCDM:RFSP:MSP:AVG 10?
Syntax
:MEASure:WCDMa[:CONTinuous]:RFSPectrum:MSPectrum:OBW
Parameters
There are no parameters.
Description
Starts a continuous measurement of the occupied bandwidth. To read out the latest
measurement result use the FETC:WCDM:RFSP:MSP:OBW command.
Query
This query command will start the measurement and return a result value as soon as
the first measurement have been completed. The result delivered will contain one
floating point number.
Example
:MEAS:WCDM:RFSP:OBW?
Syntax
:MEAS:WCDMA[:CONTinuous]:RFSPectrum:ACLR
Parameters
There are no parameters.
