• Manufacturer: ETC [List of Unclassifed Manufacturers]

Clock Frequency Examples
4.5
In order to avoid permanent toggling of the downstream counters as a result of analogue noise of the input
signals while the measuring system is in standstill, a digital filter can be optionally activated for the square-
wave outputs (pin / bit GFE).
automatically set at 2048 / f

Note that in the switching range to the automatic activation / deactivation of this filter, the A/B output signals
are not speed-proportional in each case!
