6.23.6 Sampling interval, filter
For imc µ-CANSAS-B1, sampling rates can be set in steps of 1, 2, and 5. The available sampling interval for
the imc µ-CANSAS-B1 extends from 60s to 0,5 ms.
µ-CANSAS-B1 Filter settings
Off: Output of the last value sampled at the output clock rate set
Mean value: The output value is the mean value over (output clock rate [ms] / 500µs) values. For
temperature measurement, only averaging filtering is available.
Anti-Aliasing-Filter: Low-pass filtering of the input signal with critical damping characteristics, 3rd order.
Cutoff frequency = 1/6 of the output frequency (1/7 at the 0,5 ms output clock rate)
Butterworth: Filtering of the input signal with Butterworth characteristics
Default setting: 3rd order. Cutoff frequency = 1/6 of the output frequency (1/7 at 0,5 ms output rate). At
output intervals >= 2s, an averaging filter is automatically used.
Bessel: Filtering of the input signal with Bessel characteristics
Default setting: 3rd order. Cutoff frequency = 1/6 of the output frequency (1/7 at 0,5 ms output rate). At
output intervals >= 2s, an averaging filter is automatically used.
