Modulation Accuracy (EVM & Spectral Flatness)
This section provides the remote control SCPI commands for the WLAN Modulation Accuracy
measurement from within the List Sequencer. This measurement is available only if you have the
WLAN measurement application licensed on the test set.
For more detailed information about the Modulation Accuracy measurement, refer to the online help
associated with the WLAN 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 WLAN measurement application, which is
available on the Agilent website, www.agilent.com/find/mxa.
Modulation Accuracy measurement SCPI commands
There is a set of SCPI commands available to program the WLAN Modulation Accuracy (EVM &
Spectral Flatness) measurement when it is used in the WLAN mode. To set up the WLAN
measurements from within the Sequence Analyzer mode you need to prefix the SCPI commands with
LSEQuencer:WLAN.
For example, the [:SENSe]:EVM part of the EVM SCPI commands is replaced with:
[:SENSe]:LSEQuencer:WLAN:EVM.
Also, the [:SENSe]:FLATness part of the Spectral Flatness SCPI commands is replaced with:
[:SENSe]:LSEQuencer:WLAN:FLATness.
The following commands are used to set up the modulation accuracy measurement.
[:SENSe]:LSEQuencer:WLAN:EVM:TIME:INTerval <integer>
[:SENSe]:LSEQuencer:WLAN:EVM:TIME:OFFSet <integer>
[:SENSe]:LSEQuencer:WLAN:EVM:TIME:RESult[:STATe]:AUTO OFF|ON|0|1
