Processing sequential .psdata files

Postby Elecmuso » Mon Sep 18, 2017 6:11 am

I am running my picoscope in a slow sampling mode which acquires data for 10 seconds at 100kS, saves the file to disk, then repeats until stopped. Each file is between 200kB and 500kB (I guess the size depends on the signal activity though the variations surprised me). The test (that I am having someone run remotely for me) occurs over several hours and there are hundreds of files produced.

I am looking for events where the AC voltage exceeds some value. Can I automatically process each of these output files with the resulting output being a list of files that have the exceedance? Thereby saving me form loading each file, and visually scanning the output manually.

As an example, lets say they have the names abc.psdata, abc(2).psdata, abc(3).psdata, ... , abc(499).psdata

The output of this macro (or whatever it would be) is a list of 1 or more filenames eg. 'abc(27).psdata'

Hi Elecmuso,

You would be better off setting a mask for the maximum voltage level, and then using Alarms to save a file on mask failure. That way you wouldn't need to do any processing. I have attached an example data file, which uses the internal Signal Generator and will stop autosaving when you reduce the voltage level to, say 1V in the Sig Gen.

Regarding the file variations how many buffers are you saving?
