Test and Measurement

Acquire and Send Data from Test and Measurement Equipment

In a single environment, you can build flexible test systems, automate testing routines, perform design verification, and analyze and visualize live data as you collect it.

When working with one or more standalone instruments such as oscilloscopes, arbitrary waveform generators, and signal analyzers, you use Instrument Control Toolbox to control the instruments and acquire data from them. You can quickly establish communication with instruments via industry-standard communications protocols such as GPIB, VISA (incuding USB), TCP/IP, and UDP and via industry-standard instrument drivers such as IVI and VXIplug&play. Multiple instrument manufacturers are supported including Keysight, Rohde & Schwarz, and Tektronix. You can also build test systems based on LXI, PXI, and AXIe standards.

When working with plug-in data acquisition boards, you connect to supported boards from multiple vendors using Data Acquisition Toolbox. Because many boards provide both analog and digital input and output capabilities, you can control motors and sensors as well as collect and analyze live data.

Acquire Images and Video from Cameras and Frame Grabbers

With Image Acquisition Toolbox you can acquire images and video directly into MATLAB and Simulink from PC-compatible imaging hardware. With support for multiple hardware vendors, you have the choice of a range of imaging devices from inexpensive Web cameras or industrial frame grabbers to high-end scientific cameras that meet low-light, high-speed, and other challenging requirements. Once you have acquired images, you can extract features and perform further analysis using MathWorks image and video processing products.

Analyzing Your Test Data

Once you have acquired the data, you can use analysis and visualization tools in MATLAB and related data analysis products. Acquiring and analyzing the data in the same environment lets you quickly extract the information you need from your data. Using interactive tools and command-line functions, you can perform tasks such as signal and image processing, statistical analysis, digital filtering, curve fitting, and nonlinear optimization. In addition, you can build graphical interfaces for data acquisition and live analysis of your test data.

When working with acquired data, you can use digital filtering routines to focus on the signal or feature of interest and easily view time-domain data in the frequency domain. When working with image data, you can restore noisy or degraded images and analyze shapes and textures. For projects that involve acquiring data repeatedly, you can investigate the statistics of a phenomenon over time.
