The Advantest R3361B is a synthesized spectrum analyzer spanning 9 kHz to 3.6 GHz, engineered for signal analysis, component testing, and EMC measurements. It delivers ±1 dB total level accuracy across a -130 dBm to +25 dBm measurement range, with exceptional frequency stability from an internal reference oscillator (±2 × 10⁻⁷/day). The instrument features a 70 dB QP dynamic range for EMC applications—nearly double conventional spectrum analyzers—and includes an internal tracking generator (0 dBm to -50 dBm output) for S-parameter and insertion-loss characterization. Resolution bandwidth spans 30 Hz to 1 MHz with selectable video filtering to 1 MHz. The unit weighs 15 kg and operates from 90–250 VAC (selectable), consuming less than 220 VA.
