Hello, I am using the Lock-In amplifier start-up kit. I generate an output waveform and get 2 inputs back - reference and measured signal. I connected the output with a coax wire to the 2 input channels (using BNC-2120) in order to test the program and the results aren't good. When I increase the frequency of the waveform the results even get worse (up to 1000 Hz needed). I am using PCI MIO-16E-1 (PCI 6070), max reading rate 1.25MSa/s, and I understand that the start-up kit was written to much lower rates. I have another DAQ card PCI-6143 which has A/D converter for each channel (I think) but do not have analog output. I thought about using this one as input only and the first one as output, but I don't know how to do it (need RTSI cable?) I have 3 questions: 1. What is the best configuration for my purpose, 1 card or 2 different ones? (also available to me PCI-6154) 2. How do I synchronize 2 different cards? 3. How can I find the optimum input and output rates? What are the limitations (min/max requierments) of the Lock-In amplifier? Is it possible to see the censored parts? I am using LabView8.0 thank you, Noam.

Lock-In amplifier capabilities

Unfortunately, the example program was written using TDMS file I/O functions, which were not available for LabVIEW 8.0. I've rewritten the code using some basic file I/O functions in LabVIEW and attached it below.
