Who's familiar with lockin amplifier startup kit?

Solved!
Go to solution

Dear all:

   I have downloaded the lockin startup kit and then using its subvi to develop a lockin amplifier. Base on the instruction on lockinpll.vi, the data column can identify which data column is reference signal. However, in my vi, if I choose 0 column for reference signal, no amplitude of the signal will outcome and a wrong phase (theta) will outcome. If I choose 1 column for reference signal, the amplitude of the signal will outcome correctly (R) but the phase (theta) is always 0. How can I solve the problem?

My VI is modified from the demo provided by the startup kit, why it isn't work?
