I am using a 6023E card and need to input 2 similiar channels into Labview and see the amplitude and phase differences. I have the program working for simulated inputs but the problem (according to NI) seems to be that the time delay in switching between channels causes the phase numbers to be wrong.
Has anyone used a sample and hold vi or something like it that will allow both signals to be read with respect to the same reference? I realize that there are better cards that will do this but this is a student lab and we need 16 of them so cost is a big problem. Any suggestions would be appreciated. Thanks Dave
