external sample clock with pulse width measurement

[UliK]

Dear all,

I am using a NI 6220 board (programming with ANSI C) and would like to perform a "single pulse-width measurement" using an external gate signal and an external signal as source.

Using the  "DAQmxCreateCIPulseWidthChan" command the program and card works only partly as intended. Namely, the external gate did work, but the card uses the internal 80 MHz time base signal instead of the external source connected to the default source pin (PFI 8).

I tried to route another PFI pin to the default source pin using the "DAQmxConnectTerms" command but this did not help either.

Obviously, I am missing something...

Best, Uli
