QPSK EVM
This section provides the remote control SCPI commands for the TD-SCDMA Code Domain Power
(CDP) measurement from within the List Sequencer. This measurement is available only if you have the
TD-SCDMA measurement application licensed on the test set.
For more detailed information about the QPSK EVM measurement, refer to the online help associated
with the TD-SCDMA measurement application, which is also available in PDF format (“User’s and
Programmer’s Reference”) on the Agilent website, www.agilent.com/find/e6640a.
You can also refer to the measurement guide for the X-series TD-SCDMA measurement application,
which is available on the Agilent website, www.agilent.com/find/mxa.
QPSK EVM measurement SCPI commands
There is a set of SCPI commands available to program the TD-SCDMA QPSK EVM measurement when
it is used in the TD-SCDMA mode. To set up the TD-SCDMA measurements from within the Sequence
Analyzer mode you need to prefix the SCPI commands with LSEQuencer:WCDMa. For example, the
[:SENSe]:EVMQpsk part of the QPSK EVM SCPI commands are replaced with
[:SENSe]:LSEQuencer:WCDMa:EVMQpsk.
The following commands are used to set up the QPSK EVM measurement.
[:SENSe]:LSEQuencer:WCDMa:EVMQpsk:BANDwidth[:RESolution]
[:SENSe]:LSEQuencer:WCDMa:EVMQpsk:BANDwidth:SHAPe
:CALCulate:LSEQuencer:WCDMa:EVMQpsk:LIMit:RMS
:CALCulate:LSEQuencer:WCDMa:EVMQpsk:LIMit:FERRor
[:SENSe]:LSEQuencer:WCDMa:EVMQpsk:MEAS:OFFSet
[:SENSe]:LSEQuencer:WCDMa:EVMQpsk:MEAS:LENGth
[:SENSe]:LSEQuencer:WCDMa:EVMQpsk:SPECtrum
[:SENSe]:LSEQuencer:WCDMa:EVMQpsk:FILTer[:RRC][:STATe]
[:SENSe]:LSEQuencer:WCDMa:EVMQpsk:FILTER:ALPHa
[:SENSe]:LSEQuencer:WCDMa:EVMQpsk:CRATe
