How to synchronize the waveform acquired using two systems at two different points simultaneously?

[heahkl]

I am using two system with DAQCard-700 to acquire waveform at two different points. How can I time stamped the data so that I can match the waveform from both side point-to-point? I am using LabWindows/CVI for my application.

There's no real accurate way of doing this without using another signal to synchronize the acquisitions. You could use the same signal sent to each board to trigger the acquisitions, or you could use a reference signal and a counter to measure the offset between signals.
