Filter
The filter is set in the Filter section.
Filter - Digital Modulation
Selects the baseband filter (see chapter 5.8.3.4, "Baseband Filter - Custom Digital
Mod", on page 290).
SCPI command:
[:SOURce<hw>]:BB:DM:FILTer:TYPE on page 565
Filter Parameter - Digital Modulation
Sets the filter parameter.
The filter parameter offered ("Roll Off Factor" or "B x T") depends on the currently selected
filter type.
SCPI command:
[:SOURce<hw>]:BB:DM:FILTer:PARameter:APCO25 on page 564
[:SOURce<hw>]:BB:DM:FILTer:PARameter:COSine[:ROLLoff] on page 564

[:SOURce<hw>]:BB:DM:FILTer:PARameter:PGAuss on page 564
[:SOURce<hw>]:BB:DM:FILTer:PARameter:RCOSine on page 564
[:SOURce<hw>]:BB:DM:FILTer:PARameter:SPHase on page 564
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.
SCPI command:
[:SOURce<hw>]:BB:DM:FILTer:PARameter:LPASs on page 564
[:SOURce<hw>]:BB:DM:FILTer:PARameter:LPASSEVM on page 564
[:SOURce<hw>]:BB:DM:FILTer:PARameter:APCO25Lsm:GAUSs on page 565
[:SOURce<hw>]:BB:DM:FILTer:PARameter:APCO25Lsm:LOWPass on page 565
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.
SCPI command:
[:SOURce<hw>]:BB:DM:FILTer:PARameter:COSine:BANDwidth on page 565
Oversampling - Digital Modulation
Determines the upsampling factor. If the check box is activated, the most sensible param-
eter values are selected. The value depends on the coherence check. If the check box
is deactivated, the values can be changed manually.
SCPI command:
[:SOURce<hw>]:BB:DM:FILTer:OSAMpling:AUTO on page 563
[:SOURce<hw>]:BB:DM:FILTer:OSAMpling on page 563
