Quadrature Oscillator with Power Supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12302
Indian Lab Suppliers supplies the Quadrature Oscillator with Power Supply (Product ID: 12302) as part of its electronics engineering lab equipment range. It is an op-amp oscillator that produces a sine wave and a cosine wave 90° apart.
Quick Answer
In a quadrature oscillator the signal passes round a loop of integrating stages, so the two outputs sit exactly 90° apart; in X-Y mode on a CRO the two outputs trace a circle, which confirms the 90° difference. A selector switch gives three frequencies by changing component values, and two potentiometers (coarse and fine) set the feedback for a steady, undistorted output. Frequencies are checked on a digital frequency counter; the counter and 20 MHz CRO are not included. An internal ±15 V DC, 50 mA supply powers the op-amp.
