INPut<ip>:ATTenuation <Attenuation>
This command defines the total attenuation for RF input.
If an electronic attenuator is available and active, the command defines a mechanical
attenuation (see INPut<ip>:EATT:STATe on page 903).
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 371
INPut<ip>:ATTenuation:AUTO <State>
This command couples or decouples the attenuation to the reference level. Thus, when
the reference level is changed, the R&S FSV/A determines the signal level for optimal
internal data processing and sets the required attenuation accordingly.

Parameters:

*RST: 1
Example:
INP:ATT:AUTO ON
Couples the attenuation to the reference level.
Manual operation: See " Attenuation Mode / Value " on page 371
INPut<ip>:ATTenuation:AUTO:MODE <OptMode>
Selects the priority for signal processing after the RF attenuation has been applied.
