scope waveform post-processing

Hi,

I have a waveform file from an oscilloscope, i was able to plot it with this command. i would like to post process the waveform, measure, rise/fall time, voltage peak to peak, jitter...

Can someone please give some reference, guiadance to do the post processing,

load SQ8.mat

w=double(Channel_1.Data)/(sqrt(var(double(Channel_1.Data))));

plot(w)

Thanks and regards,

Hey Roberto!

I’m assuming that the oscilloscope data has been captured and saved appropriately into the variable w.

You may use the following functions and links to get your desired outputs –

There is no built-in function to evaluate the jitter value of a signal. However, you can use other available functions to write an algorithm that would get you the expected results. Also, consider using the Signal Analyzer App in MATLAB to quickly find delays, latency, and other parameters. The functions mean and finddelay could also be of help to you.
