The aim of this analysis is to verify the electrical compatibility of the interfaces which exist between TWTA(Travelling Wave Tube Amplifier) which is equipment of the Ka-band payload in COMS (Communication, Ocean and Meteorological Satellite) and external equipments. For each interface, this study checked the compatibility between equipments for the power links, commands, digital telemetry, analog telemetry, and failure condition or AIT(Assembly, Integration and Test) errors. In addition with this interface compatibility verification, this study outputs electrical and manufacturing recommendations to be applied at harness level.
