W-CDMA Programming Commands
Occupied Bandwidth (OBW)
This section provides the remote control SCPI commands for the Occupied Bandwidth (OBW)
measurement from within the List Sequencer. This measurement is available only if you have the
W-CDMA measurement application licensed on the test set.
For more detailed information about the OBW measurement, refer to the online help associated with the
W-CDMA 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 W-CDMA measurement application, which
is available on the Agilent website, www.agilent.com/find/mxa.
OBW measurement SCPI commands
There is a set of SCPI commands available to program the W-CDMA OBW measurement when it is used
in the W-CDMA mode. To set up the W-CDMA measurements from within the Sequence Analyzer
mode you need to prefix the SCPI commands with LSEQuencer:WCDMa. For example, the
[:SENSe]:OBWidth part of the OBW SCPI commands are replaced with
[:SENSe]:LSEQuencer:WCDMa:OBWidth.
The following commands are used to set up the OBW measurement.
[:SENSe]:LSEQuencer:LTETdd:OBWidth:BANDwidth[:RESolution]
[:SENSe]:LSEQuencer:LTETdd:OBWidth:BANDwidth:SHAPe
[:SENSe]:LSEQuencer:LTETdd:OBWidth:PERCent
[:SENSe]:LSEQuencer:LTETdd:OBWidth:XDB
CALCulate:[SENSe]:LSEQuencer:LTETdd:OBWidth:LIMit:FBLimit
CALCulate:[SENSe]:LSEQuencer:LTETdd:OBWidth:LIMit[:TEST]
[:SENSe]:LSEQuencer:LTETdd:OBWidth:FREQuency:SPAN
[:SENSe]:LSEQuencer:LTETdd:OBWidth:FREQuency:SPAN:FULL
[:SENSe]:LSEQuencer:LTETdd:OBWidth:FREQuency:SPAN:PREVious
