how to record and playback waveform?

[deswong]

Hi,

I would like to record the waveform of my signal and then playback again for analysis purposes.

My current VI can read the signals from 2 channels of my oscilloscope (as shown in the picture) using the waveform chart. How and what should I include in my VI so that I can playback the signal waveform so that I can trace back the place where I previously could not stop the signal in time to obtain the result i want?

Also, is my cross correlation connected properly in the VI? Because while running the signal, this is the waveform I got from the above 2channels waveform (which I think its wrong).

 

Thanks for much! Your help is greatly appreciated! 😃

To record (or to save) the acquired data on to disk use the TDMS vi's placed in Files I/O-> TDM streaming..

 There will be some example shipped along with the LV on how to use this files.

So once all the data have been stored to the disk read them back (u have to create another vi for reading them) and populate the same to the w/f chart (read small chunks of data = the sampling rate , so that you can exactly play back the data when u were acquiring. This also will not hog your CPU if the data stored is huge)
