long time storage

Post by Gunther Zielosko »

Hello,
is there any possibility to save an oscillogram over a long time? I want save an long time ECG on the PC. By the way how can I make a walking oscillogram like an mechanical ECG?

Hi

What kind of time scale are you wanting to save?
What sampling rate do you need over that time?
What scope do you have?

Be aware of the file format you save to and the sampling rate. Image files aren't a problem, but if you want the actual data in .csv, .txt, .mat formats the files will get huge over a large time base with high sample rates. .csv, .txt can take forever to save while the matlab (.mat) save time is far better. But there is a glitch in the software when the matlab file size gets up to around 350 MB and above, the picoscope software does something to the file and it won't load into matlab at that point. I just went through all of this myself.
