Loopback Bit Error Rate (BER)
This section provides the remote control SCPI commands for the TD-SCDMA Loopback Bit Error Rate
(BER) 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 BER 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.
Loopback Bit Error Rate (BER) measurement SCPI commands
There is a set of SCPI commands available to program the TD-SCDMA BER 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:TDSCDMA. For example, the
[:SENSe]:CDPower part of the BER SCPI commands are replaced with
[:SENSe]:LSEQuencer:TDSCdma:CDPower.
The following commands are used to set up the BER measurement.
[:SENSe]:LSEQuencer:TDSCdma:CDPower:RINTerval
[:SENSe]:LSEQuencer:TDSCdma:CDPower:ANALysis:SUBFrame
[:SENSe]:LSEQuencer:TDSCdma:CDPower:SCLength
[:SENSe]:LSEQuencer:TDSCdma:CDPower:CDCHannel
