3 VMA Mode
3.9 SEM Measurement
Rel Stop
Sets a relative power level limit at the stop frequency for the selected inner offset,
ranging from –200 to +50 dBc.
The fail condition is set remotely by [:SENSe]:SEMask:OFFSet
[n]:INNer:LIST:TEST for each inner offset channel.
You can turn off (not use) specific inner offset channels remotely with
[:SENSe]:SEMask:OFFSet[n]:INNer:LIST:STATe.
The query returns values currently set to the inner offset stop relative power limits.
When sending the remote 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 for this parameter always returns 12 values.
