Spectrum Monitoring

Capture and analyze IQ data from the air using preamble or energy detection

Configure your NI™ USRP™ radio as a preamble detector or energy detector to detect and capture specific signals from the air. You can specify standard-based or custom waveforms for detection. Use the captured data to analyze, simulate, test, and validate wireless systems.
