Data gathered using the 2 kHz packet/frame rate is measured over 0.5 seconds. The ADAS1000-3/ADAS1000-4 internal programmable low-pass filter is configured for
either 40 Hz or 150 Hz bandwidth. The data is gathered and post processed using a digital filter of either 0.05 Hz or 0.5 Hz to provide data over noted frequency bands.
