Pulse Length
0.3ms – 99.9ms in increments of 0.1ms
to set the duration of an output pulse
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.
