Counters
When multiple sample clocks on my buffered counter measurement
occur before consecutive edges on my source, I see weird behavior.
Why?
Duplicate count prevention ensures that the counter returns correct data for
counter measurement in some applications where a slow or non-periodic
external source is used.
Refer to the Duplicate Count Prevention section of Chapter 7, Counters ,
for more information.
How do I connect counter signals to my M Series device?
The Default Counter Terminals section of Chapter 7, Counters , has
information on counter signal connections.
