The Rigol RSA3045 is a real-time spectrum analyzer delivering RF signal analysis from 9 kHz to 4.5 GHz with guaranteed signal capture of 7.45 µs or shorter. It combines traditional spectrum analysis with real-time processing across up to seven visualization modes—including Density, Spectrogram, and Power vs. Time—enabling detection of transient and intermittent signals that conventional analyzers miss.
