4.1.4 Rise Time Gadget

RiseTime-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).

Analyze Rise Time

1. Start with a new workbook and click the button to import the Step Signal with Random Noise.dat file under the <Origin EXE Folder>\Samples\Signal Processing path.
2. Highlight Column B and select Plot: Line: Line in the menu to create a graph.
   
   
   
   
3. Double-click the X axis to open the Axis dialog box. Go to the Scale tab and set the axis range and major ticks as shown in the image below.
   
   
   
   
4. Click the OK button and the graph will be updated as shown below:
   
   
   
   
5. Select Gadgets: Rise Time from the Origin menu to open the Rise Time: addtool_rise_time dialog box. Go to the Display on Graph tab, and click the Rise Time and Rise Range check boxes.
   
   
   
   
6. Click OK button, and you will see that a yellow rectangle is added to the plot. Move the rectangle horizontally on the rise signal step.
   
   
   
   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 at the top right corner of the rectangle. Then select New Output. The results will be output to the Script Window.
   
   
   
   

Analyze Fall Time

1. This gadget also allows you to get the fall time and fall range in a graph. Move the rectangle horizontally on the fall signal step.
   
   
   
   
2. Click the triangle button and select Preferences in the fly-out menu to open the Rise Time Preferences dialog. Go to the ROI Box tab and select Fall Time in the Tool drop-down list.
   
   
   
   
3. Click the OK button, the Fall Time and Fall Range values are shown at the top of the rectangle.
   
   
   
   
4. Click the triangle button and select New Output. The results will be output to the Script Window.
