Before you begin
- You have a Run with ingested telemetry data.
- You know which Channels you want to compare.
How signal comparison works
Plotting multiple Channels together lets you see how signals behave relative to each other over the same time range. There are two ways to compare signals, each suited to a different kind of analysis:- Overlay in the same Panel to directly compare signals on a shared axis. Use this when you want to spot correlations, timing differences, or dependencies between signals with similar scales.
- Split into adjacent Panels to compare signals with different scales or units side by side without overlapping them. Use this when visual separation makes the comparison clearer.
Compare signals
- In Sift’s homepage, enter the Run name in the Search box.
- In the Runs table, click the Run you want to analyze.
- Click Explore.
- Select a Panel type to add to the workspace.
- In the Channels tab, click or drag a Channel onto the Panel to plot it.
- Add additional Channels depending on how you want to compare them:
- To overlay signals, add one or more related Channels to the same Panel.
- To compare side by side, split the Panel or click to add a new Panel, then plot a related Channel in it.
- Optional: Use range controls to zoom into a time range and focus on a specific period of interest.
