The filter parameter offered ("Roll Off Factor" or "B x T") depends on the currently selected
filter type.

Cut Off Frequency Factor - Digital Modulation
(available for filter parameter Lowpass and APCO25 (LSM) only)
Sets the value for the cut off frequency factor. The cut off frequency of the filter can be
adjusted to reach spectrum mask requirements.
Remote command:

​[:​SOURce]:​BB:​DM:​FILTer:​PARameter:​APCO25Lsm:​LOWPass​ on page 243
Bandwidth - Digital Modulation
Determines the bandwidth of the cosine filter, so that the function H(f) = 0 is fulfilled for
f >= (1+RollOff)*Bandwidth/2.
Remote command:
​[:​SOURce]:​BB:​DM:​FILTer:​PARameter:​COSine:​BANDwidth​ on page 243
Impulse Length - Digital Modulation
Displays the number of filter tabs. If the check box is activated, the most sensible parameter
values are selected. The value depends on the coherence check. If the check box
is deactivated, the values can be changed manually.
Remote command:
​[:​SOURce]:​BB:​DM:​FILTer:​ILENgth:​AUTO​ on page 241
​[:​SOURce]:​BB:​DM:​FILTer:​ILENgth​ on page 241
Oversampling - Digital Modulation
Determines the upsampling factor. If the check box is activated, the most sensible parameter
values are selected. The value depends on the coherence check. If the check box
is deactivated, the values can be changed manually.
Remote command:
​[:​SOURce]:​BB:​DM:​FILTer:​OSAMpling:​AUTO​ on page 241
​[:​SOURce]:​BB:​DM:​FILTer:​OSAMpling​ on page 241
More - Filter - Digital Modulation
Calls the menu for displaying the filter characteristic of the currently selected filter.
