The Marconi IFR Aeroflex 6204A is a 46 GHz microwave test set that combines signal generation, power measurement, and frequency analysis in a single portable instrument. It delivers calibrated power measurements, real-time fault location on transmission lines, and scalar network analysis across the 10 MHz to 46 GHz band. The integrated synthesized signal source operates as a CW generator or sweep instrument, while dedicated power meter and frequency counter channels handle independent measurement tasks with high accuracy and resolution.
