rising edge phase shift

[JWinstanley]

Hi

I am using a CDAQ 9178 and have a 9229 analogue card. I have two 28V square waves that are aroudn 90 degrees sperated. The frequency is around 10-20hz. I am sampling at 10000 samples per second and recording 20000 samples of data. so two seconds. 

How can i measure phase shift between the two rising edges for every pulse. 

I am using the 9229 analogue card as it can handle the higher voltage plus all channels are sampled simultaneous 

I have attahced my programme.

Hi JWinstanley,

You can measure the phase shift by measuring the time difference between rising edges of each signal.

I have attached a document which may be of use to you: http://www.ni.com/white-paper/4529/en/

Best of luck!
