Hi There and welcome to the forum.
You can find the Waveform Library under the File
menu in the PicoScope software. You sign-in to the library using the same credentials as you use for this forum, and must have a PicoScope connected and an internet connection.
Once you are signed in, you can actually close the library itself and perform your tests as normal. When you then choose File
, you can choose Save and Share
This will save a local copy to your PC and will upload the waveform to the library.
Any problems, just drop me a message here
