The Aeroflex 2399 is a portable spectrum analyzer covering 9 kHz to 2.9 GHz, engineered for RF and microwave signal analysis in laboratory and field environments. It delivers 1 Hz frequency resolution, amplitude measurements spanning +30 dBm to −110 dBm, and integrated AM/FM demodulation with audio output. The instrument combines a fully synthesized local oscillator with 0.1 dB amplitude resolution and low residual spurious (≤−85 dBm), making it suitable for component characterization, system validation, and signal monitoring across communications, defense, and aerospace applications.
