Analog Communications Training System (8080)
The system consists of six instructional modules supported by six system instruments and courseware that provides hands-on exercises in the generation, transmission, and reception of amplitude, double sideband, single sideband, frequency, and phase modulated signals (AM, DSB, SSB, FM, and PM).
A door on the top of each instructional module provides access to circuit boards, test points, and fault insertion switches.
