Advantest R3132 Series Spectrum Analyzers
2 models with full specifications from Advantest.
The Advantest R3132 Series of RF spectrum analyzers, featuring the Advantest R3132 and Advantest R3132N, is designed for signal analysis across a frequency range of 9 kHz to 3 GHz. Built around a direct digital synthesizer (DDS) local oscillator, these instruments are tailored for RF development, manufacturing, and service environments requiring consistent frequency span and level accuracy. The series is characterized by its high-speed sweep capabilities, achieving a trace update rate of up to 20 traces per second for efficient real-time monitoring.

Models in this series
Core Measurement Performance
Both models in the series deliver a frequency span accuracy of ±1% or less and an overall level accuracy of ±1.5 dB, supported by a built-in auto-calibration system. For demanding signal environments, the instruments offer a 1 dB gain compression point of >+105 dBµV for frequencies of 20 MHz or higher. They also feature a second-order harmonic distortion of <= -70 dBc and a third-order intermodulation distortion of <= -75 dBc, making them highly reliable for resolving low-level signals.
Impedance and Connectivity Configurations
The primary distinction between the models in this series is the RF input configuration. The Advantest R3132N is configured as a 75-ohm instrument, featuring a 75-ohm N-type female input connector and a 117 dB dynamic range, which is ideal for television, cable, and broadcast signal environments. The standard Advantest R3132 caters to applications requiring alternative impedance matching. Both instruments feature a 6.5-inch color TFT LCD with a resolution of 640 x 480 pixels for displaying detailed measurement traces.
Physical and Operating Specifications
Designed to fit into standard test benches, these analyzers measure 424 mm in width, 177 mm in height, and 420 mm in depth, weighing 14 kg or less without options. They operate within a temperature range of 0 °C to +50 °C. The resolution bandwidth (RBW) range spans from 300 Hz to 3 MHz in a 1-3 sequence, allowing for flexible selectivity during close-in signal analysis.
