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 454
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
FSW determines the signal level for optimal
internal data processing and sets the required attenuation accordingly.
