The ETB-024 trainer is designed to demonstrate the working principle of a phase shift audio oscillator, widely used in signal generation and analog electronics. This trainer enables students to understand how phase shift networks and amplifiers can be combined to produce stable sinusoidal waveforms at audio frequencies.
The built-in power supply and accessible test points allow direct observation of the oscillator’s performance using an oscilloscope or frequency counter. The model is ideal for studying RC phase shift networks, feedback principles, and oscillator circuit design in electronics labs.
Key Features:
Demonstrates the generation of audio-frequency sine waves
Uses RC phase shift network and amplifier configuration
Built-in regulated power supply for standalone operation
Output terminals for waveform observation and frequency measurement
Ideal for analog electronics, circuit theory, and signal generation training
Durable and compact educational setup for practical lab sessions
