Filter Type (Filter Type)
The following digital filter types are available: Gauss, Sharp, IIR, and Mean. The features of each filter are listed
below.
Filter Type Features Operation Type
Gauss Frequency characteristics with a smooth attenuation slope FIR
Linear phase and constant group delay
No ripples present in the passband
No overshoot in the step response
Low order and short delay
Sharp Frequency characteristics with a sharp attenuation slope
(−40 dB at 1 oct)
FIR
Linear phase and constant group delay
Ripples present in the passband
Comb-shaped stopband
IIR Attenuation slope steepness between those of the SHARP and
GAUSS filters
IIR
Non-linear phase and non-constant group delay
No ripples present in the passband and stopband
Characteristics similar to those of analog filters
Compared to Sharp and Gauss filters, lower cutoff frequency
possible
Mean
Comb-shaped frequency characteristics FIR
Linear phase and constant group delay
No overshoot in the step response
IIR-LowPass Computes at 10 MS/s regardless of the setting. IIR
Filter Band (Filter Band)
When the filter type is set to Gauss, Sharp, or IIR, you can select the filter band. The type of filter band that you
can select depends on the filter type.
Filter Type Filter Band
Gauss Low-Pass
Sharp Low-Pass, High-Pass, Band-Pass
IIR Low-Pass, High-Pass, Band-Pass
Cutoff Frequency (CutOff)
When the filter type is set to Sharp, Gauss, or IIR and the filter band is set to Low-Pass or High-Pass, you can
set the cutoff frequency. The ranges and resolutions are indicated below.
