The Marconi IFR Aeroflex 6203B is a microwave test set engineered for scalar network analysis, power measurement, and frequency characterization across 10 MHz to 26.5 GHz. The instrument delivers real-time fault location with 0.1% accuracy and return loss measurement against distance, enabling rapid transmission line diagnostics. A synthesized signal source with 1 Hz resolution operates as either a CW generator or swept source, completing 400-point sweeps in under 200 ms with high stability and fast step times.
