Counting a Pulse

[Sam P.]

Hello, my name is Sam and I'm 17 and working on a project at Texas Tech University. I'm a bit confused as to how to make a program that will wait for 1 millisecond and take the high end reading of a pulse then at 1.1 milliseconds it will read the low pulse then loop it back to the beginning again. I'm using an NI-DAQmx Base 6008 unit and using LabVIEW 7.1. Help would be much appreciated.

Hello Sam,

I'm not quite sure what you are trying to measure. If you are trying to measure an analog signal could you use a 1ms delay using the delay function in LabVIEW and then start an acquisition that acquires data at the upper rate (10kS/s) for 2 samples? If you are trying to measure a digital signal, it will have to be entirely timed in the software. If you are trying to use the counter to do a timing measurement, this is not supported by the hardware. Tell us a little bit more of your application and what you are trying to do and we can offer you some more advice!
