Emerging software can now scan a PDF of a waveform, digitize it, and compare it to your live signal in real-time. Tools like PicoDiagnostics’ AI Assistant are beginning to integrate with PDF libraries. You simply snap a photo of the PDF waveform from a manual, and the software aligns the timebase automatically.
