The Marconi IFR Aeroflex 6203 is a microwave test set that integrates signal generation, power measurement, frequency counting, and scalar network analysis into a single portable instrument. Operating from 10 MHz to 26.5 GHz, it delivers fast synthesized signal generation with 1 Hz resolution, capable of executing 400-point sweeps in under 200 ms. The instrument combines analog sweeper speed with synthesizer precision across Start/Stop, Center/Span, and CW sweep modes. Built-in power measurement, frequency counter, scalar analyzer, and real-time fault location with 0.1% accuracy make it suitable for laboratory and field characterization of microwave components and transmission line systems.
