The Advantest R3132 is a spectrum analyzer spanning 9 kHz to 3 GHz, purpose-built for wideband signal analysis and electromagnetic compliance testing. It delivers amplitude measurement capability from +30 dBm down to noise floor, with total level accuracy of ±1.5 dB maximum. The instrument features a 6.5-inch TFT color LCD display with VGA output support, enabling real-time signal visualization on external monitors. A built-in frequency counter provides 1 Hz to 1 kHz resolution with marker-based accuracy tied to frequency reference stability of ±2 × 10⁻⁶/year (±1 × 10⁻⁷/year with option). Resolution bandwidth ranges from 1 kHz to 3 MHz in 1-3-10 sequence, with optional narrow-band filters down to 30 Hz.
