The Advantest R3132N is a high-performance 75-ohm spectrum analyzer covering a frequency range from 9 kHz to 3 GHz. Designed with a Direct Digital Synthesizer (DDS) local oscillator, it offers excellent level accuracy, rapid sweep times of up to 20 traces per second, and a wide 117 dB dynamic range. It is ideal for RF testing, telecommunications, and cable TV (CATV) applications where 75-ohm characteristic impedance is required.
