9 Instructions for use
9.1 Output pulse length and maximum counting rate
On the one hand, the duration of an output pulse must be long enough so that the customer’s control
system can process it. On the other hand, the length of the output pulse limits the maximum counting
rate. Because output pulses must not overlap, the interval between edges must be at least as long as
one output pulse length. If the interval is shorter, then this edge will be suppressed meaning that the
edge will not initiate an output pulse.
The following figure illustrates how every other edge is suppressed because of a too long of an output
pulse length.
