5.1.4 Rise Time Gadget



Summary

The Rise Time Gadget can be used to analyze the rising and falling stages of a step-like signal in a graph. With this gadget, you can intuitively select an area on the graph with a rectangle, and then calculate the rise time or fall time within that area.

Minimum Origin Version Required: OriginPro 2015 SR0

What you will learn

  • How to select a specific region of the signal by moving and resizing a region of interest (ROI).
  • How to mark Rise Time (Fall Time) and Rise Range (Fall Range ) in the graph.
  • How to switch the tool between Rise Time and Fall Time.
  • How to output analysis results of Rise Time (Fall Time).

    In the graph, you can see the Rise Time and Rise Range values are shown at the top of the rectangle.
    The two blue vertical lines go through the two indicators marking the Rise Time.
    The two blue horizontal lines that display the Low Reference Level and High Reference Level go through the two indicators marking the Rise Range.
    The two red horizontal lines display Low State Level and High State Level.
  7. Click the triangle button Triangle button.png at the top right corner of the rectangle. Then select New Output. The results will be output to the Script Window.
