We have a linear sensor that gives out two sinusoidal signals 90 degrees apart, these are put through an interpolator (which we cannot play with the electronics inside) and then into a PC for Transmission Error Measurement. The problem we are facing is a large error on the PC, which is caused by the two signals not being exactly 90 degrees apart. There is approximately 2-3 degrees of error.
hi,
Thanks for the explanation, I'm still kicking myself for misreading your posted limits.
