The final design of a field portable microprocessor-based, microwave measuring and analysis instrument to be used for S-band transmitter fourth-harmonic power analysis and its impact on X-band reception in a dual S-X-band system is described.
Device provides 12 outputs isolated from each other by 70 dB at 100 MHz, frequency range of 0.1 to 100 MHz, less than 2 deg phase shift over temperature change of 0 to 50 C, and computer level output to monitor module signal quality.
