How are the signals from the 6602 different when you connect the clock signal to the PCI-MIO-16E-1 card? It does actually sound like a problem with the source current of the device you are using for the clocking signals.
Will the card aquire analog signals when it alone is connected to the clocking pulses?
How much current can the function generator provide?
If you could come back to me with that information I might be able to hgelp you further
Hi again edavide,
Any luck with this issue?
Sorry for updating my problem. Yes, I solved this problem, although I am not sure how I did it. I think it is due to the function generator that I have been using. Now I replaced it with a new one, and it does the job. But still the old function generator works fine when I tested it. So I am a bit confused. Anyway, it does not seems that it is a problem generated by NI card. Many thanks for your kind help.
