View multiple signals together in Explore to understand how they relate to each other over time.

​
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

  1. In Sift’s homepage, enter the Run name in the Search box.
  2. In the Runs table, click the Run you want to analyze.
  3. Click Explore.
  4. Select a Panel type to add to the workspace.
  5. In the Channels tab, click or drag a Channel onto the Panel to plot it.
  6. 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 by right-clicking its tab and selecting a split direction.
    • The split duplicates the Panel and creates an independent Panel that can be configured separately. Alternatively, click to add a new Panel from scratch.
  7. Optional: To move a Channel to a different axis, click and drag the Channel entry in the Timeseries Panel legend and select the target axis.
  8. Optional: To apply axis and style settings to all Channels at once, open the Panel settings, click the Channel tab, select All Channels from the Group by list, and configure the settings. Available in Timeseries and FFT Panels.
  9. Optional: Click Time Range in the toolbar to align all Panels to the same time range.
    • In the Synced Panel Time dialog, select Absolute to set a specific time range or Relative to align to T-0, then click Sync All.
  10. Optional: To analyze Channels with different scales independently, open the Timeseries Panel settings, go to the General tab, and turn on the Split by Y-Axis toggle.
  11. Optional: Use range controls to zoom into a time range and focus on a specific period of interest.
