Product Code : SCL-EELE-12238
Indian Lab Suppliers supplies the Study of Complementary-Symmetry Transistor Power Amplifier with power supply and 1 meter (Product ID: 12238) as part of its electronics engineering lab equipment range. It is a training board for studying a complementary-symmetry transistor power amplifier, its DC conditions and its signal performance.
Quick Answer
Students measure DC voltages at set test points with and without signal, the DC bias current with and without signal, and the idling (quiescent) current of the output pair. They then measure input and output impedances and power gain. The circuit uses three on-board transistors and a 9 V DC, 100 mA IC-regulated supply connected internally; bias current is read on a DC milliammeter with 5 mA and 50 mA ranges. A decade audio generator, AC millivoltmeter, AF output power meter, decade resistance box, 3¾-digit multimeter and 20 MHz oscilloscope are required.
