What Is the Voltage Controlled Oscillator Used For?
A VCO is an oscillator whose output frequency changes with a DC control voltage; the slope of frequency against voltage is called the VCO gain. Together with a phase detector and an amplifier it forms a phase-locked loop: the detector compares the VCO output with an incoming signal, and the amplified error voltage steers the VCO until the two are locked. Varying the DC voltage and recording the output frequency gives the voltage-to-frequency characteristic of this section in communication and analog electronics practicals.
Frequently Asked Questions
What supplies and components are on the trainer?
A fixed +10 V and a variable 0–10 V DC regulated supply, a 0–10 kΩ potentiometer, a 3 kΩ resistance and a capacitor rated 400 V; the circuit diagram is printed on the front panel.
What comes with it?
The standard accessories are a power cord, patch cords and an instruction manual. Oscilloscopes and frequency counters are not among them; JLab lists those as separate items.
Does JLab also list a phase-locked loop trainer?
Yes. The Phase Locked Loop Circuit (PLL) trainer is a separate item for studying a phase-locked loop and calculating its lock range and capture range.
Who manufactures this VCO trainer?
Jain Laboratory Instruments Pvt Ltd (JLab) builds it at its works in Ambala, Haryana, and supplies it direct.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a communication and electronics lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The trainer comes from JLab’s own works, not a reseller, so colleges, dealers and importers order from the maker. JLab exports worldwide and ships to buyers in every region — for example Liberia in West Africa, South Africa in Southern Africa, Brazil in South America, Switzerland in Western Europe and Canada in North America. Tender details are on the JLab lab tenders page.
