Transmit and Capture Waveforms with Wireless Testbench

Generate, transmit, and capture RF waveforms using NI USRP radios in MATLAB.

When to Use

• Transmitting a waveform (test tone, standard-compliant signal, custom IQ) over the air
• Capturing IQ data from a frequency band
• Loopback testing (transmit and capture on the same radio)
• Multi-antenna transmit or capture
• Continuous transmission for prolonged testing
• Background capture for long-duration acquisition

When NOT to Use

• Setting up or connecting a USRP radio for the first time — use the matlab-set-up-usrp-radio skill
• FPGA targeting workflows — see Target NI USRP Radios
• Intelligent capture with preamble/energy detection — see Spectrum Monitoring
• Multi-device synchronization — see Radio Management
