The Marconi IFR Aeroflex 2399C is a portable spectrum analyzer delivering signal analysis from 300 Hz to 3 GHz with 1 Hz frequency resolution across a fully synthesized local oscillator architecture. The instrument measures amplitude from +30 dBm to −110 dBm and features nine simultaneously displayed markers, semi-automated measurement functions, and AM/FM demodulation. Input protection to ±50 Vdc, variable resolution bandwidth from 30 Hz to 3 MHz, and video bandwidth control from 1 Hz to 1 MHz enable precise spectral characterization in telecommunications, broadcasting, research, and field service environments.
