Hartley and Colpitts Oscillator Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12098
Indian Lab Suppliers supplies the Hartley and Colpitts Oscillator Trainer (Product ID: 12098) as part of its electronics engineering lab equipment range. It is a patch-cord trainer for building and studying Hartley and Colpitts LC oscillators with NPN transistors.
Quick Answer
Both oscillators use an NPN transistor with an LC tank: the Hartley circuit takes its feedback from a tapped (split) inductance, the Colpitts circuit from a split capacitance, and in each the frequency is set by f = 1/(2π√LC). Students complete every circuit with patch cords, so each design is built step by step before the sine output is viewed on an oscilloscope. The trainer runs on +12 V DC from the supplied SMPS adaptor. Output frequencies are not stated, so please confirm them at quotation.
