NI usb 6008 DAQ / Frequency measurement

[thoalfukar]

Hello Everybody,

I am working on a project using NI USB 6008 DAQ, I am mearing square signal pulses from a generator using that DAQ. everything working fine but I need to measure the frequency of that pulses in addition to the measurements I do with that DAQ. 

the attached picture shows you an example of what kind of signal I measuring.

Any of you have an idea about how to measure the frequency, I have tried to use some examples but they did not work with me. I will be really appreciated your help. 

Many thanks

Hi @thoalfukar

There are built in functions for waveform analysis that you could use to find out the frequency of a waveform. 

For example, you can use a 'single tone measurement.vi' to determine the frequency (see attached)

There are also an express vi called 'tone measurement' which would help you step by step if you are not sure what to do.

This should help you determine your waveform.

Thanks,

HR
