a scan system for each channel.
In the following figures, the digital filter is Off, recording interval is 20 ms (with 2

When the digital filter is off, the scan widths and dead times between channels are
fixed to the values shown in the figure above regardless of the recording intervals.
When the digital filter is on, the scan widths and dead times between channels vary
in accordance with the recording intervals.
