LeCroy Oscilloscopes: MATLAB PC Oscilloscope Software

Making Custom Measurements on LeCroy Oscilloscopes using MATLAB

MATLAB® is a software environment used by over 1,000,000 users to make measurements, analyze data, control instruments, and build test systems. MATLAB handles a range of computing tasks from data acquisition and analysis to application development. MATLAB integrates mathematical computing, visualization, and a powerful technical language.

Read the summary brief called Using MATLAB with LeCroy Oscilloscopes to learn the value of using MATLAB with digital oscilloscopes and how MATLAB enables custom measurements to be made directly on LeCroy oscilloscopes.

MATLAB includes tools for:

Data acquisition

Data analysis and visualization

Instrument Control

Algorithm prototyping and development

Modeling and simulation

Programming and application development

Test system development

XDEV Advanced Customization package for LeCroy Oscilloscopes

Only LeCroy oscilloscopes completely integrate MATLAB into the scope�s processing stream by allowing you to create and deploy a new measurement or math algorithm directly into the WaveShape Analysis Engine and display the result on the DSO in real-time! There is no need to establish remote communication between the scope and another program, create a new reference waveform or transfer large data files between the analyzer and another program. With the XDEV Advanced Customization Package, you extend LeCroy oscilloscopes to include your most recent new technology algorithms the same day they are created. The XDEV Advanced Customization Package is available for these LeCroy oscilloscopes:

WaveMaster & SDA Series

WavePro Series

WaveRunner Series

The following presentation shows in four easy steps how to use MATLAB to make custom measurements on LeCroy oscilloscopes such as the LeCroy WaveMaster:

Configuring and Controlling LeCroy oscilloscopes in MATLAB

MATLAB can configure and control LeCroy oscilloscopes remotely over TCP/IP or directly on the oscilloscope using the MATLAB Instrument Control Toolbox. MATLAB provides a graphical tool, called Test & Measurement Tool, which allows you to interactively communicate with your instrument without writing code.

Being able to configure and control your oscilloscope from MATLAB is essential if you need to develop interactive or automated test applications that consist of changing the setup of the oscilloscope multiple times. MATLAB can also be used to develop hybrid test systems consisting of a LeCroy oscilloscope and other instruments from LeCroy or other manufacturers.

Once data is in MATLAB, you can analyze and visualize it using interactive tools and command-line functions for data analysis tasks such as signal processing, statistical analysis, digital filtering, curve fitting, and nonlinear optimization. Data acquisition and analysis work can also be incorporated into GUI-based applications. MATLAB can automatically generate reports in HTML or other formats so that you can share your results with others.

To configure and control your oscilloscope, you will need MATLAB, Instrument Control Toolbox, and a MATLAB instrument driver built for your oscilloscope. Ask your LeCroy account manager or visit the LeCroy MATLAB resource page for obtaining MATLAB, Instrument Control Toolbox, and the appropriate MATLAB instrument driver for your instrument.
