The Advantest R3465 is a modulation spectrum analyzer covering 9 kHz to 8 GHz, engineered for detailed waveform and modulation characteristic analysis across radio systems development, production adjustment, and field testing. The instrument delivers 90 dBc dynamic range (100 dBc with preselector), exceptional frequency stability at 2 × 10⁻⁸ / day, and residual FM below 3 Hz peak-to-peak. It combines spectrum analyzer and digital transmission tester modes in a single platform.
