3.9 SEM Measurement
Abs2 Stop
Sets the 2nd 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 and Manual. If set to Couple = ON, the Abs2 Stop power level limit is coupled
to "Abs2 Start" on page 1683, resulting in a flat limit line. If set to Man (Couple =
OFF), Abs2 Start and Abs2 Stop take different values, resulting in a sloped limit line.
The query returns values currently set to the offset stop 2nd absolute power limits.
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 always returns 12 values.
