[:SENSe]:SEMask:OFFSet[n][:OUTer]:LIST:STATe
When sending the command, missing values are not permitted; that is, if you want
to change values 2 and 6, you must send all values up to 6. Subsequent values
remain unchanged. The query returns 14 values for WLAN Mode, or 12 values for
other Modes.

Offset Freq Define
Enables you to select offset frequency definition. Each standard defines each offset
frequency from Carrier.
For example, 3GPP2 requires the “Carrier Center to Meas BW Edge” definition, and
LTE conformance test requires “Carrier Edge to Meas BW Center” and/or “Carrier
Edge to Meas BW Edge” definition. MSR standard requires “RF BW Edge to Meas
BW Center” and/or “RF BW Edge to Meas Edge” definition.
“Meas BW Edge” means the edge frequency of resolution bandwidth closer to the
carrier that is represented by Meas BW and Res BW settings. Actual center
frequency of Meas BW and the limit line have ½ Meas BW offset when the Meas BW
Edge is selected.
