The DSB / SSB AM Transmitter Trainer is a versatile self contained stand alone unit useful in the study and demonstration of carrier generation, amplitude modulation, DSB, SSB, and AM transmitter. The unit consists of audio generator, AM modulator, carrier generator, and transmitter antenna. The unit is housed in an elegant cabinet with a well spread intelligently designed circuit layout on front panel. Multi-coloured test points are provided at various stages in the circuit to observe the waveforms and voltages. It is strongly supported by a comprehensive instruction manual complete with theory and operating details.
