A maintenance method and system is provided. The method includes providing a device comprising a thru state switch and condition circuits. The device is permanently connected between a feed system and an antenna. The device receives a first control signal and disables a connection between the analyzer and the antenna. The device receives additional control signals and enables conditions. The device generates altered responses of the feed system. The altered responses are associated with the conditions. The altered responses are used to normalize an analyzer and the feed system or troubleshoot a communication system.
