Each channel is equipped with a passive low-pass filter, an anti-
aliasing filter and a 16-bit A/D converter. All channels are sampled
synchronously with a common quartz-controlled clock pulse.
The filters protect against voltage transients and limit the signal rise
rate, reduce high frequency components and especially the noise
voltage above half the sampling rate of the A/D converter by 80 dB,
thus achieving very small measuring errors in an exceptionally large
amplitude range. This is also valid under extreme operating
conditions like transient voltages at the output of converters.
