113User Manual 1177.5856.02 ─ 07
Manual operation: See " Shifting the Display ( Offset )" on page 49
[SENSe:]POWer:NCORrection <State>
This command turns noise cancellation on and off.
If noise cancellation is on, the R&S FSWP performs a reference measurement to
determine its inherent noise and subtracts the result from the channel power measure-
ment result (first active trace only).
For more information see " Noise Cancellation " on page 50.
Parameters:
<State> ON | OFF | 1 | 0
*RST: 0
Example:
POW:NCOR ON

INPut<ip>:ATTenuation <Attenuation>
This command defines the total attenuation for RF input.
If you set the attenuation manually, it is no longer coupled to the reference level, but
the reference level is coupled to the attenuation. Thus, if the current reference level is
not compatible with an attenuation that has been set manually, the command also
adjusts the reference level.

Parameters:
<Attenuation> Range: see data sheet
Increment: 5 dB (with optional electr. attenuator: 1 dB)
*RST: 10 dB (AUTO is set to ON)
Default unit: DB
Example:
INP:ATT 30dB
Defines a 30 dB attenuation and decouples the attenuation from
the reference level.
Manual operation: See " Attenuation Mode / Value " on page 50
