QPSK EVM
This section provides the remote control SCPI commands for the cdma2000 QPSK EVM measurement
from within the List Sequencer. This measurement is available only if you have the cdma2000
measurement application licensed on the test set.
For more detailed information about the cdma2000 QPSK EVM measurement, refer to the online help
associated with the cdma2000 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 cdma2000 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 cdma2000 QPSK EVM measurement when it
is used in the cdma2000 mode. To set up the cdma2000 measurements from within the Sequence
Analyzer mode you need to prefix the SCPI commands with LSEQuencer:C2K. For example, the
[:SENSe]:EVMQpsk part of the QPSK EVM SCPI commands are replaced with
[:SENSe]:LSEQuencer:C2K:EVMQpsk.
The following commands are used to set up the QPSK EVM measurement.
[:SENSe]:LSEQuencer:C2K:EVMQpsk:BANDwidth[:RESolution]
[:SENSe]:LSEQuencer:C2K:EVMQpsk:BANDwidth:SHAPe
:CALCulate:LSEQuencer:C2K:EVMQpsk:LIMit:RMS
:CALCulate:LSEQuencer:C2K:EVMQpsk:LIMit:FERRor
[:SENSe]:LSEQuencer:C2K:EVMQpsk:MEAS:OFFSet
[:SENSe]:LSEQuencer:C2K:EVMQpsk:MEAS:LENGth
[:SENSe]:LSEQuencer:C2K:EVMQpsk:SPECtrum
[:SENSe]:LSEQuencer:C2K:EVMQpsk:FILTer[:RRC][:STATe]
[:SENSe]:LSEQuencer:C2K:EVMQpsk:FILTER:ALPHa
[:SENSe]:LSEQuencer:C2K:EVMQpsk:CRATe
