MATLAB oscilloscope application - example

A user interface developed in MATLAB for collecting data from a scope and passing the measured data

Description

This example demonstrates how you can use MATLAB to develop an application that both collects data from an oscilloscope and performs mathematical calculations and visualization on the data. Combining MATLAB with your oscilloscope transforms the scope into a complete test bench station for data collection and data analysis. In one application, you now have direct access to reliable scope measurements as well as advanced data analysis and report generation capabilities.

MATLAB provides a lot of functions for signal processing including signal filtering. In this example, we created several analysis routines using these functions to show you how to use MATLAB to analyze your data including making measurements unique to your application.

You may use this application with your oscilloscope using the built-in analysis routines. You are also welcome to modify the application (free-of-charge) for other instruments or to write your own analysis routines providing you also post your modified version of this MATLAB oscilloscope application on MATLAB Central for others to use.

Are the two windows swapped in the example screen capture? The first one looks filtered & the second looks raw. I may just be looking at it wrong.

The code is user friendly and easy to modify, although there is not enough examples; along with the examples in the "Tektronix TDS 2024 MATLAB instrument driver", users can do most of the things they want to do.
