Hartley’s oscillator is intended for generation of high frequency signals like carrier wave signals in a communication system. This consists of a Tank circuit made up of an inductor and a fixed capacitor shunted by a voltage-variable capacitor network. Using this trainer the student experiments how variable frequency is generated. An external Oscilloscope of 15MHz is required for observation of the generated sine wave signals.

1. To connect a Hartley oscillator and observe and compare the collector and base Wave forms.

2. To check the frequency of the oscillator.
