SIM: Gemini Systems Interference Monitor

This paper describes SIM (Systems Interference Monitor) which was developed to demonstrate compliance of the man-rated Gemini launch vehicle to the interference control requirements of MIL-E-6051C. The SIM incorporates simultaneous monitoring and remote control of many widely separated test points from a central location. The system includes a self-verification capability, two-wire high-input impedance signal conditioners, a plug-In capability for adapting to on-the-spot criteria changes, and data that are immediately presented in permanent record for a quick-look 'go-no-go' review and comprehensive analysis at a later date.
