Rel Start
Sets a relative power level limit at the start frequency for the selected offset. The
relative power level limit ranges from –200 to +50 dBc.
The fail condition is set remotely by [:SENSe]:SEMask:OFFSet[n]
[:OUTer]:LIST:TEST for each offset channel test.
You can turn off (not use) specific offset channels remotely with
[:SENSe]:SEMask:OFFSet[n][:OUTer]:LIST:STATe.
The query returns values currently set to the relative power test 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 returns 14 values for WLAN Mode, or12 values for
other Modes.

Notes Comma-separated list of values
OFFSet 1 is for BTS, 2 for MS. Default is BTS
Note that Offset sub op code 2 is supported only in Modes other than SA. In SA mode, Offset sub op
code 1 is used for both BTS and MS
