Oscilloscope Viewer (Web)

Browser-based waveform viewer for local oscilloscope data (.trc, .csv, .txt).

What It Does

• Loads local waveform files directly in the browser.
• Parses LeCroy .trc files in-browser (worker + fallback parser).
• Groups files by event using filename patterns like C1-00012.trc.
• Displays event waveforms per channel with pan/zoom and decimation.
• Supports SG-filter overlay for quick smoothing checks.
• Lets you show/hide channels with a channel visibility menu:
  • Show All
  • Hide All
  • Per-channel toggles

Notes

• This web app is now viewing-focused.
• Fit routines, fit/batch-fit tools, and fit result export/import workflows were removed.

Usage

1. Open index.html in a modern browser.
2. Click Select Folder and choose your data folder.
3. Pick an event from the dropdown.
4. Use:
   • Tool: Zoom to drag a zoom box
   • Tool: Pan to drag view (hold Shift for vertical pan)
   • mouse wheel to zoom (Shift/Ctrl for Y zoom)
   • double-click a plot to reset that channel view
5. Use Channels menu to hide/show channel plots.
6. Optional: run SG Filter on a selected channel.
