Save to disk on trigger in PicoScope 5

PicoScope, our oscilloscope software has the useful ability to save a waveform to disk (complete with a time / date stamp) each time a trigger event occurs. This can prove invaluable when tracking down intermittent faults, especially those that happen infrequently over a period of hours or days.

The trigger mode can be enabled by selecting Settings | Trigger. By default a maximum of 100 waveforms will be recorded to disk (to avoid filling your hard drive). This default can be overridden by editing the settings in the psw.ini file as shown below:

  1. Close PicoScope if you currently have it running
  2. Using a text editor such as notepad, open psw.ini in the PicoScope working directory (C:Program FilesPico TechnologyPico Full in a default installation)
  3. Under the heading [PicoScope for Windows], add a line MaxSOTFiles=200 (where 200 is the maximum number of files you wish to save)
  4. Save psw.ini and start PicoScope
