The Advantest R3463 is a modulation spectrum analyzer engineered for digital mobile communication system analysis across 9 kHz to 3 GHz. It combines spectrum analyzer and digital transmission tester modes to deliver signal analysis, component characterization, and EMC measurements in a single instrument.
– Technical Specifications
Frequency Range: 9 kHz to 3 GHz
