Experimental Training Equipments-> Phase Lock Loops

[1]   Click to Enlarge PHASE DETECTION & MEASUREMENT, USING PLL Objectives of this experiment: The phase locked loop contains 1. Low pass filter. 2. Phase detector & Comparator. 3 VCO. the frequency generated by VCO is determined by the different values of capacitors & resistors. The phase detector compares the difference VCO frequency with the incoming signal frequency. It then develops an error voltage, which is proportional to the phase & frequency difference between the two signals. To verify the phase lock state when the VCO frequency are equal. Built in regulated power supply: +15V/300mA Input Supply: 230 VAC/50Hz mains operated. Dimension: 27cms x 17cms x 10cms. Weight: 500gms See Enlarge Click to Enlarge VOLTAGE CONTROLLED OSCILLATOR (VCO) USING PLL Objectives of this experiment: To determine the frequency of the voltage controlled oscillator determined by Resistors & Capacitors. By varying the input voltage the output frequency can be varied. Built in regulated power supply: +5V/300mA Input Supply: 230 VAC/50Hz mains operated. Dimension: 27cms x 17cms x 10cms. Weight: 500gms See Enlarge Click to Enlarge PHASE LOCK LOOP FREQUENCY MULTIPLIER & SYNTHESIZER To construct PLL multiplier & synthesizer. The input frequency can be generated b clock generator provided on the trainer. The PLL locks the input signal with the VCO and the locked frequency is multiplied by X1 to X9.
