What software are you using? PicoScope 5.xx or 6.xx?
With 5.xx, you can set up a 'Save On Trigger' session. This will automatically write each triggered screen to the last working folder on your hard drive. Save one file into a empty folder and name it something to tag it as save on trigger files. You want to do this to prompt you that these are SOT files so you don't open one later and run with it making a mess on your hard drive somewhere because the file has SOT enabled.
Then go to your Settings/Trigger and select 'Save on trigger'. The default is 100 screens then it stops saving until you stop and start the scope again, then it does another 100.
PicoScope 6.xx is much more powerful and easier to record. While is does not write screens to your hard drive, it does save them in the buffer. These never stop because the buffer scrolls. You can set this for up to 1000 screens and the oldest fall off when the new screens are captured. Then you can save one screen or all screens in the buffer to your hard drive in a single file.
Using PicoScope 6, with long time bases, you can sample faster than any other automotive scope available. So, don't be afraid to turn up the power and capture long screen times.
