XK-GP1 Analog communication trainer constitutes by signal source module, frequency meter module and 8 pcs training modules. It adopts modular structure, each experiment module can be put flexibly. Each module can realize the fixed functional experiment, and by combining several modules, can realize the system experiment, such as the AM modulation and demodulation, FM modulation and demodulation. The design of the modules is not only focus on measuring the experiment input signal and output signal, but also lay emphasis on measuring and analyzing the experiment intermediate process and intermediate variables. It is suitable for the college students to carry out the high frequency electronic circuit learning and experiment.
