Signal Generator and Amplifier
Signal Generator and Amplifier (Product Code: SLE/PHY/130) is a combined function generator and power amplifier used to drive loudspeakers, vibrators and other wave apparatus in school and college physics and electronics laboratories. It produces sine, rectangular and triangular waves from 0.1 Hz to 99.9 kHz, shown on a digital display with 0.01% frequency accuracy, and delivers up to 4.5W into a 4 Ω load. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Signal Generator and Amplifier Used For?
One instrument covers two jobs. As a signal generator it supplies clean test waveforms for oscilloscope and circuit work, and as an amplifier it has enough power to drive a loudspeaker, vibration generator or resonance apparatus directly, which makes it a natural choice for standing waves on strings, air-column resonance, sound demonstrations and frequency-response measurements.
Use the 600 Ω output with its x1, x0.1 and x0.01 attenuator for low-level signals into electronic circuits, and the low-impedance output for loads around 4 Ω, where maximum power transfer occurs. The output withstands prolonged short circuits, which suits student benches, but it is still good practice to turn the amplitude to zero before connecting a new load. It works equally well as a signal generator for the electronics lab and as a driver for physics wave practicals.
Supplier
This Signal Generator and Amplifier is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab and is based in Ambala, Haryana.
