Transistor Bias Stability with power supply 1KHz Oscillator and 2 meters Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12173
Indian Lab Suppliers supplies the Transistor Bias Stability with power supply 1KHz Oscillator and 2 meters (Product ID: 12173) as part of its electronics engineering lab equipment range. It is a board for studying how temperature shifts the operating point of a transistor amplifier and how that affects stability and distortion.
Quick Answer
A PNP transistor amplifier runs from a −12 V DC, 20 mA regulated supply, with a fixed 1 kHz oscillator (amplitude control) as the signal source. The transistor is heated in an electric oven read by a 0–110 °C thermometer, while a 65 mm 0–15 V DC voltmeter and a 65 mm two-range DC current meter track the operating point. Students measure leakage current against temperature, see the Q point shift, check its effect on amplifier stability, and watch distortion appear on an oscilloscope. The current meter ranges are listed as 500 and 10 with unclear units; please confirm them at quotation.

Frequently Asked Questions
Why does the Q point move with temperature?
Leakage current and base-emitter voltage change as the transistor heats up.
How is the transistor heated?
In a built-in electrically heated oven.
What else is needed?
A 20 MHz oscilloscope to view distortion.
