Wireless Testbench

Explore and test wireless reference applications in real time on SDR hardware

Wireless Testbench™ provides reference applications that are ready to run on off-the-shelf software-defined radio (SDR) hardware such as USRP™ using over-the-air signals for high-speed data transmit, capture, and spectrum monitoring.

Using MATLAB^® command line instructions, you can connect to supported SDR hardware, configure and execute prebuilt FPGA bitstreams as reference applications, and perform real-time measurements.

Using the configurable preamble detector, you can define a trigger to capture only the signal of interest for offline analysis in MATLAB.

High-Speed Transmit and Capture

Perform full-rate (up to 250 Msps) data transmission and reception on supported SDR hardware using onboard memory. Analyze baseband signals in real time using optimized data I/O between MATLAB and SDR hardware.
