Description

Comprises an experiment board, housed within a board carrier, for use in conjunction with, and powered by the Master Unit (700020, supplied separately) teaching a practical course on the fundamentals and applications of shift keyed signals and modems, experiments being wired using 2 mm safety cables (700022, supplied separately). Course content, experiment instructions and tasks are taught via course-specific software.
