The Marconi IFR Aeroflex 2395 is a portable spectrum analyzer covering 9 kHz to 26.5 GHz, engineered for RF and microwave signal analysis across modern communication systems. Weighing 12 kg with a rugged construction, it delivers laboratory-grade performance in field-deployable form. The 6.4-inch TFT color LCD display (640 x 480 pixels) renders signals clearly in high ambient light conditions.
Technical Specifications
Frequency range spans 9 kHz to 26.5 GHz with 1 Hz resolution. Input impedance is 50 Ohm, accepting signal levels from +30 dBm to -110 dBm with ±50 VDC protection. The 1 dB compression point exceeds -10 dBm across 100 kHz to 26.5 GHz at 0 dB attenuation. Phase noise measures -90 dBc at 10 kHz offset. Displayed Average Noise Level (DANL) improves by typically 5 dB between 1 MHz and 13 GHz relative to 300 Hz resolution bandwidth baseline values.
Resolution bandwidth ranges from 10 Hz minimum to 3 MHz maximum, with digital RBW filters (Option 05) achieving <5:1 selectivity at -60 dB/-3 dB points. Sweep times for a 10 kHz span measure <0.9 seconds at 100 Hz RBW, <3 seconds at 30 Hz RBW, and <4.5 seconds at 10 Hz RBW.
