3 Due to the integrated filters, a minimum sampling rate of 1 kHz is recommended for the correct operation
of this module, even if an even lower sampling rate (time base) can be set in the ibaPDA configuration.

AI-24 V DC R/C low-pass, 1st order, 25 kHz
AI-24 V AC Like AI-24 V DC, in addition R/C high-pass, 1st order, 1 Hz
IEPE R/C high-pass, 1st order, 1 Hz or 0.1 Hz, can be adjusted
Analog anti-aliasing filter (Butterworth), 4th order
Sampling rate ≤ 8 kHz: cutoff frequency = 4 kHz
Sampling rate > 8 kHz: cutoff frequency = 20 kHz
Analog anti-aliasing filter (delta-sigma)
Oversampling = 16 * sampling rate
Cutoff frequency = 0.49 * sampling rate
