The Rigol RSA3045N is a real-time spectrum analyzer designed for RF signal analysis across 9 kHz to 4.5 GHz, with integrated Vector Network Analysis (VNA) capabilities from 100 kHz to 4.5 GHz. Built on a quad-core processor running embedded Linux, the instrument captures and characterizes transient and complex signal behaviors through seven real-time visualization modes including Normal, Density, Spectrogram, and Power vs. Time.
