Channel History

Channel History

The Channel History provides an oscilloscope-style waveform display for detailed DMX channel analysis.

Opening Channel History

Click any channel cell in the Universe Monitor grid to open the waveform view for that channel.

Features

• Step-style DMX trace with gradient fill, matching the discrete nature of DMX values (0–255)
• Selectable time windows — 5s, 10s, 30s, or 60s of visible history
• Pause / Resume — freeze the view for inspection without losing incoming data
• Hover crosshair — shows exact value and timestamp at any point on the waveform
• Min / Max band — dashed indicators show the value range over the visible window
• 60 FPS rendering with smooth continuous scrolling

Use Cases

• Verify that a dimmer channel is fading smoothly
• Check that a strobe channel is triggering at the expected rate
• Diagnose timing issues between sources
• Monitor a control channel for remote triggering
