Offset
Reduces the transition range between the measurement paths, 0 -> 1 and 1 -> 2, by
the set value, the so-called cross-over level. Thus, you can improve the measurement
accuracy for signals with a high peak-to-average ratio, since the headroom for modula-
tion peaks becomes larger. However, the S/N ratio is reduced at the lower limits of the
transition ranges.

Attenuator Mode
Requires an R&S frequency selective power sensor.
"User" Disables the automatic setting of the input attenuation.
"Auto" Enables the automatic setting of the input attenuation.
"Once" Adjusts the input attenuation one time, then disables the automatic
setting.
Remote command:
CALCulate<Measurement>[:CHANnel<Channel>]:INPut:ATTenuation:AUTO

Attenuation
Requires an R&S frequency selective power sensor.
Available if Attenuator Mode is set to "User".
Sets the input attenuation. Only two values are possible, 0.0 dB and 30.0 dB. The
entered value is rounded to the next value.
