The Marconi IFR Aeroflex 2382 is a 100 Hz to 400 MHz spectrum analyzer engineered for signal analysis, characterization, and response measurement across audio, ultrasonics, HF, VHF, and UHF bands. Built on advanced RF design with microprocessor control, it delivers ±1 dB level accuracy and ±0.4 dB frequency response. The instrument operates as a standalone unit or integrates into Automatic Test Equipment systems via GPIB programmability.
