The ETB-203 Voltage Controlled Oscillator (VCO) Trainer is a dedicated training module designed to study the working principle and behavior of a voltage-controlled oscillator circuit. This trainer enables students to explore how the output frequency of an oscillator can be varied by changing the input voltage, a fundamental concept in analog modulation, frequency synthesis, and phase-locked loop (PLL) systems.
The ETB-203 includes:
An integrated VCO circuit
Onboard regulated power supply
Frequency and voltage test points
Circuit block diagram on the panel for visual aid
High-quality components and sturdy build for repeated academic use
Ideal for analog and communication electronics labs, this trainer helps learners analyze the V-F (voltage-to-frequency) relationship, waveform characteristics, and practical applications of VCOs in signal processing and control systems.
