VCO & PLL Trainer

A phase-locked loop (PLL) circuit is a feedback system that combines a voltage controlled oscillator (VCO) and a phase detector in such a way that the oscillator signal tracks an applied frequency or phase modulated signal with the correct frequency and phase.

  • The single board trainer helps to studies the following :
    1. To adjust center frequency of a PLL.
    2. To observe the lock range.
    3. To observe the maximum and minimum capture frequencies.
  • The trainer contains :
    1. Dual channel IC regulated power supply.
    2. Components on board.
  • Additional Accessories Required :
    • Dual trace oscilloscope
    • Sine wave generator
