Parameters:
<Offset> Range: -200 dB to 200 dB
*RST: 0dB
Example:
DISP:TRAC:Y:RLEV:OFFS -10dB
Manual operation: See "Shifting the Display (Offset)" on page 87

INPut: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:EATT:STATe on page 237).
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.
This function is not available if the Digital Baseband Interface (R&S FSW-B17) is
active.
Parameters:
<Attenuation> Range: see data sheet
Increment: 5 dB
*RST: 10 dB (AUTO is set to ON)
Example:
INP:ATT 30dB
Defines a 30 dB attenuation and decouples the attenuation from
the reference level.
Usage: SCPI confirmed
Manual operation: See "Attenuation Mode / Value" on page 88
INPut:ATTenuation:AUTO <State>
This command couples or decouples the attenuation to the reference level. Thus, when
the reference level is changed, the R&S FSW determines the signal level for optimal
internal data processing and sets the required attenuation accordingly.
