Filter Type
This parameter allows you to select the type of IF filter (post ADC, digital filter) that is used. This is an
advanced control that normally does not need to be changed.

Digital IF BW
Allows you to select the type of IF filter (post ADC, digital filter) that is used. This is an advanced
control that normally does not need to be changed.
The Digital IF bandwidth is determined from the Span. The Digital IF BW and Span relation is
determined by the following formula.
Digital IF BW = Span x 1.5
This equation holds except for the case when only the value is clipped to the max value. Furthermore,

Gaussian and Flattop are available in all DIF configurations. For the other
filter types, the filters are only available with PXA or when Option B40 is
installed.
