You pick the mode when you create a project, and switch whenever you want from Menu → Switch to digital / analog mode.

Digital

Pulses that are high or low on a grid of steps.For clocks, data, enables, protocol frames and position-sensor signals.

Analog

Curves built from points and chords.For ramps, peaks, plateaus and any shape that needs intermediate heights.

​
What each one has

When a feature only exists in one mode, the button is still there but disabled, and the tooltip tells you why: “Templates are only available in digital mode”.

​
They are two separate projects

This matters and surprises people the first time: digital and analog are not two views of the same thing. Each mode keeps on its own:
  • Its channels and its signal.
  • Its own undo history (undoing in digital does not touch the analog work).
  • Its labels, dividers and marks.
  • Its document name — the header title changes when you switch modes.
  • Its zoom, its channel page and its view settings.
Switching modes converts nothing: it stores one project and opens the other, exactly as you left it. What is shared between both: the light/dark theme, the language, your session and the protocol settings.
The clipboard is shared too, but it is tagged: what you copy in digital cannot be pasted in analog, or the other way round. The Paste button only lights up when what you copied matches the mode you are in.

​
View mode

Beyond the two signal modes, the bottom bar has a view mode switch: it hides the grid and the cells, leaving only the waveform on a clean background. While it is on, nothing can be edited — the buttons tell you so with “Locked in view mode”. Use it to present or compare shapes without the noise of the grid.
