Hello everyone,
I am working on PWM measurement using NI 9425 Digital Input module to measure PWM on its 24 Digital I/O channels. I want to use this card in FPGA mode. Is it possible to use the NI 9425 card for measuring PWM without using single-timed loop. Is it recommended to use this NI 9425 card. since it is mentioned that it does not supports single timed loop measurement for digital signals.

You can use the DI module in the FPGA also in a "default" loop instead of the SCTL.
And you can implement your algorithm to determine PWM parameters…

The SCTL does NOT define the usability of your DI module.
Your measurement requirements are much more important…
