Abs Stop
Sets the absolute power level limit at the stop frequency for the selected inner
offset, ranging from –200 to +50 dBm. You can also toggle this function between
Couple (COUPle = ON) and Manual (COUPle = OFF). If set to Couple, the Abs Stop
power level limit is coupled to Abs Start to result in a flat limit line. If set to Man, Abs
Start and Abs Stop take different values to result in a sloped limit line.
The query returns values currently set to the inner offset stop absolute 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.
