Dependencies Gaussian and Flattop are available in all DIF configurations. For the other filter types, the filters are
only available when Option DP2, B40, or a wider IF Bandwidth option is installed
When you select a filter type other than Gaussian or Flattop when using Option B40, B85, B1A, or B1X
WBDIF, but then you either explicitly select an IF Path Selection of 10 MHz or 25 MHz (B10M/B25M),
or set a Digital IF BW equal to or narrower than 25 MHz with IF Path Selection Auto ON, the default
filter type (FLATtop) is automatically selected. If you then again set the IF Path Selection to 85 MHz
(B85), 125 MHz (B125M), or 140 MHz (B140M), the filter type remains as FLATtop
