How to compare input analog signals?

[Azim]

Hi All,

I am using DAQ PCIe6363 to collect  analog input signals. Input signal mode is in continuous adn single channel multiple sample. The sampling frequency is 2MS/s, number of sample is 100KS or less. That means DAQ collect 100KS and plot a line/curve. I want to compare the two curves. The problem is DAQ continuously collecting data and plot also in continuous. Would you please suggest is there any way to compare the curves in this continuous operations. The main purpose is to justify whether the incomeing signal maintain uniformity or not.

Many thanks

You could store one waveform in a shift register.  Then you have it in memory to compare to the new waveform.

Thanks.
