–
ABSolute and RELative both check the results against the respective limit
–
OR checks against both limits, failing if either of the limits is broken
–
AND only displays a fail if both of the limits are broken
The absolute or relative power limit value for each inner offset channel can be set
remotely with [:SENSe]:SEMask:OFFSet[n]:INNer:LIST:ABSolute or
[:SENSe]:SEMask:OFFSet[n]:INNer:LIST:RCARrier.
You can turn off (not use) specific inner offset channels remotely with
[:SENSe]:SEMask:OFFSet[n]:INNer:LIST:STATe.
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.

Abs2 Start
Sets the 2nd absolute power level limit at the start frequency for the selected inner
offset, ranging from –200 to +50 dBm.
The fail condition for each inner offset channel is set remotely using:
[:SENSe]:SEMask:OFFSet[n]:INNer:LIST:TEST:SABSolute
You can turn off (not use) specific inner offset channels remotely using:
[:SENSe]:SEMask:OFFSet[n]:INNer:LIST:STATe
The query returns values currently set to the 2nd absolute power test limits.
