As anyone an example of an acquisition controlled with the a scan clock property set to one of the GPCTR counter output?

[DITA]

I tried various alternatives like:
CWAI1.ScanClock.ClockSourceType = cwaiGPCTRLoToHiCS
CWAI1.ScanClock.ClockSourceSignal = "0"
but it appears that I can't get a scanning frequency higher than 100scans/sec.
Anyone any clue ?

Hello;

What you can do to solve the issue is to route the Counter output to one of the RTSI lines, and use the same RTSI line as the Scan clock of your Analog Input acquisition.

Hope this helps.

I tried that too, unsuccessfully. The thing is that it always scan at the same frequency (50Hz) whatever the pulse train frequency coupled to the CWAI scan clock and I don't know where this 50 Hz comes from (could that be interference from the main power supply?!).
Thanks for trying to help anyway!
