When disabled, no compensation is performed even if an external preamplifier remains
connected.

Adjust Ref Level
Activates or deactivates the automatic adjustment of the reference level to the active
filter calculation configuration. The offset is the mean of the filter calculation. The refer-
ence level offset is calculated individually for each channel the frequency response
correction settings apply to (see
"Apply to" on page 730).
Note the following prerequisites and restrictions concerning the automatic reference
level adjustment:
●
The reference level offset is only applied if frequency response correction is
enabled (see
"State" on page 729). If you disable frequency response correction,
"Adjust Ref Level" is automatically set to "Manual".
●
The reference level offset is only applied if the center frequency is within the cur-
rently covered filter frequency range.
●
The reference level offset is applied independently of a transducer reference level
offset (see
"Adjust Ref Level" on page 716).
"Auto" Activates the automatic adjustment. The original dynamic range of
the reference level is shifted by the filter calculation offset.
"Manual" Deactivates the automatic adjustment. Adjust the reference level in
the "Amplitude" settings (see
"Reference Level" on page 456).
Remote command:
[SENSe:]CORRection:FRESponse<si>:USER:ADJust:RLEVel:STATe
on page 1303
Apply to
Determines which channels the correction settings are applied to.
"All Input Src" The frequency response correction settings are applied to all active
measurement channels with the same input source. A new filter is
calculated for each measurement channel as soon as you switch to it,
or when a measurement is performed (e.g. by the Sequencer).
"Channel" The frequency response correction settings are applied to the cur-
rently selected channel only.

Load Settings
Loads a stored saveset for a user-defined frequency response correction scenario.
Existing settings in the dialog box are overwritten. The settings apply to the currently
selected channel or all channels, depending on the
Apply to setting.
