Marconi IFR Aeroflex 2022E 10KHz to 1.01GHz Synthesized Signal Generator

The Marconi IFR Aeroflex 2022E is a synthesized signal generator spanning 10 kHz to 1.01 GHz, engineered for RF development, production testing, and maintenance applications. It delivers precise frequency synthesis with configurable output levels from -127 dBm to +10 dBm, supporting amplitude, frequency, and phase modulation across internal and external sources. Electronic reverse power protection to 50 W safeguards the 50 Ω output against mismatched loads and faults.
