Hello everyone , I need a quickly help that as below : I am trying use PCI-6220 to acquired six signals from one rotation encoder (channel A, channel B,channel Z ,and their non-signals) .The encoder out signals will be square wave and 4000pulses per revolution. I set it rotation at 300rpm speed. I need show every square wave of six out channels in waveform and measure the A-B phase difference to check if the value is correct (designed value should be 90deg) . I have no idea how to measure or calculate the phase difference of two square wave base on synchronizate to acquire these two square wave from two channel on the PCI-6620.... Anyone can give a idea how to calculate the phase difference with two square wave ? Thank a lot and Thanks again... Tim

Hi U_TTT,

see message #2 of this thread for a solution.

(Instead of bringing such an old thread back to live you should start your own thread with your own specific problem!)
