What Is the Hartley Oscillator Trainer Used For?
A Hartley oscillator is an LC oscillator whose tank circuit uses a tapped inductor — in effect two coils in series — with one capacitor across them. The tap feeds part of the signal back to the amplifier, which keeps the circuit oscillating and produces a sine wave whose frequency falls as the inductance or capacitance is increased. Students measure the frequency generated and compare it with the value worked out from L and C — a standard practical in B.Sc. physics and electronics, diploma and ITI/TVET courses. A tuned wave meter is typically coupled loosely to the oscillator coil and adjusted for maximum response, and its setting at resonance gives the frequency.
What to Specify When Ordering
- Quantity — the minimum order is 10 trainers, often one per bench or student group.
- Companion trainers — Colpitts, phase shift and Wien bridge models for a complete oscillator practical.
Frequently Asked Questions
What does the Hartley oscillator trainer demonstrate?
How an LC circuit with a tapped inductor sustains oscillation. It is used to study the frequency generated and relate it to the inductance and capacitance of the tank circuit.
How is it different from the Colpitts oscillator trainer?
The Hartley circuit splits the inductance and uses one capacitor; the Colpitts circuit splits the capacitance and uses one inductor. Both give a sine wave. Only this listing mentions a variable L & C wave meter.
What details are given for the wave meter?
The listing calls it a variable L & C wave meter and gives no range, so ask JLab for the details if your practical depends on them.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics and electronics lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The trainer is built at JLab’s own works, not bought from a trader, so colleges, dealers and importers buy direct from the maker, and repeat orders and replacement parts are handled at the works. JLab exports worldwide and ships to buyers in every region — for example Norway in Northern Europe, Morocco in North Africa, Afghanistan in South Asia, Ghana in West Africa and Thailand in Southeast Asia. Tender information is on the JLab lab tenders page.
