SDR-B: Software Defined Radio

About Product

The SDR-B platform introduces students to modern communication systems using real-time hardware and GNU Radio–based software processing, enabling hands-on learning in both analog and digital modulation. With zero-installation capability and an RF agile transceiver up to 6 GHz, it delivers a seamless experience from signal generation to wireless experimentation.
