The Aeroflex 2399B is a portable spectrum analyzer for RF and microwave signal characterization across 9 kHz to 3 GHz. It delivers precise frequency measurements with 1 Hz resolution via a fully synthesized local oscillator, accepts input signals from +30 dBm to -110 dBm, and provides real-time amplitude and frequency analysis on a 6.4-inch TFT color LCD display (640 × 480 pixels). The instrument weighs 9.4 kg and operates in high ambient light conditions.
