Measurement computing USB-QUAD08

[martzak]

Hi,

Does anyone out there have any experience with Measurement Computing USB-QUAD08 board? I normally stick with NI DAQ only, but I was looking for a USB DAQ with 8 timer/counter channels and that's the only one I could find.

I'm trying to measure the period of a digital PWM signal. Specifically I want to capture 50-500 consecutive pulse periods into an array (measure period between falling edges) which are 100-10000us in duration.

At any rate, the example from their website (attached) utilizes .net references, which I am not familiar with, does not seem to do what I need.

If anyone out there has worked with this device and would like to modify the attached VI to accomplish what's needed, I would greatly appreciate your help.

I don't have any experience with the module you listed, but I do use USB-1208 quite a bit.  Have you tried using the labview vi's that come with the device?

MoReese,

Thanks for chiming in. The normal ULx VIs from MC do not work with QUAD08 device, I've verified it through trial and error and by talking with one of their applications engineer, Jeff. I'm going to try to work with him to get the attached VI to work. If I'm successful, I'll post it in this thread for others to use it, should they ever need it.
