from device specification it is not clear which is the maximum frequency that can be applied as PXI-6289 counter source using PFI <0..15>.
Do someone know it?
Thanks a lot
I think the answer to your question is not unique, but depends on the situation.
If the counter source comes from the PXI-6289 itself and the chassis processes the code locally, the maximum frequency is the one set by the PXI clock itself, i.e. up to 10 MHz.
Instead, if the software doesn't run on the PXI but on a device connected via USB, one can go up to 1 MHz.
Hope this helps!
