Issue
Need to know if the counter input on a xPDI8 meets the 140 hz specification that is called out in the Project Specification.
Environment
- xPDI8
- xPBD4
- Counter input
Cause
Need to know if the high resolution counter input on a xPDI8 or an xPBD4
Resolution
 While the xPDI8 counter input is rated for 140 Hz. this spec is based on a 50% duty cycle rate. 
 
 In any case, the minimum pulse width we can read on a high resolution counter input is 3.57 ms.  Anything less than 3.57 ms cannot be read reliably by the XPDI8.
