The Marconi IFR Aeroflex 6201B is a portable microwave test set for signal generation, frequency measurement, and power analysis across 10 MHz to 8 GHz. It delivers synthesized CW and swept signals with 1 Hz resolution, optional step attenuation down to −90 dBm, and a 90 dB dynamic range scalar analyzer. Built-in frequency counter, power meter, and real-time fault location with 0.1% accuracy enable field and benchtop characterization of microwave components and transmission line systems.
