pulse width measurement

[rothmans]

Is there anyone can give the help?

 Currently I'm doing the project to measure pusle width of a generator. The pulse width level HIGH = 100uSec and level LOW = 300uSec. It will generate 5 pulse and low for 8.3mS and continue 5 pulse and so on.

Now I'm use hardware M series Multifunction DAQ NI 6221, so how to use this hardware to capture the data pulse timing?

Thanks for your advise.

If these pulses are TTL/CMOS compatable the easiest is to use a counter and look at the pulse width measurement examples.  If this is not a standard voltage or has varying pusle widths (not a pulse train/oscillator) then you can sample it using an analog collection (use sampling of 10+ times the durration of the smallest pulse) and there are waveform analysis functions to find just about any parameter of the waveform you might be interesten in,
