rising edge phase shift



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:


Best of luck!
