Signal Generator & Amplifier
Product Code : LSK-PL-10280
Signal Generator & Amplifier (SKU LSK-PL-10280) combines a sine, square and triangular wave source with an amplifier in one bench unit and shows the set frequency on an LED display. It suits sound, waves and AC practicals in school and college physics laboratories. Production takes place at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, where Science Lab Supplies manufactures the unit and prices it for schools, colleges, contractors and distributors.

Applications and Experiments for the Signal Generator & Amplifier
Because it reads out the frequency directly, the unit suits experiments where students record frequency against a measured result, such as resonance or pitch, and its three waveforms can be compared on an oscilloscope. That makes it a versatile signal generator in the electronics lab as well as in school physics classes.
- Class 9 sound: linking displayed frequency to pitch.
- Class 11 waves: resonant frequencies of strings and springs.
- Showing a voice waveform beside a generated one, picked up with a Microphone.
- Comparing sine, square and triangular waves on a PC Oscilloscope.
- B.Sc. and polytechnic AC circuit practicals.
Standard Scope of Supply
One Signal Generator & Amplifier is supplied as a single mains-powered bench unit, as described above, with its LED frequency display and labelled 4 mm socket pairs. Loudspeakers, vibration generators, oscilloscopes and leads are separate products that can go on the same quotation.
Packing, MOQ and Lead Time
A quotation can be prepared for a single unit or a set for every student bench; it states the packing, delivery time and price for exactly that quantity. A vibration generator and an oscilloscope for a waves bench can be added to the same quotation.
With an Importer-Exporter Code, Science Lab Supplies is a registered exporter that can ship to buyers in the UAE, Saudi Arabia, Oman, the Philippines, Nepal and Bangladesh. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU). Pricing for one unit or a class set starts with a message on the contact page, an entry in the enquiry cart, or a bid through the lab tender page.
Frequently Asked Questions
Which waveforms does it provide?
Sine, square and triangular waves. The frequency is set with a range switch and a continuously variable fine control, and the LED display shows the value so students can record it directly.
Why is one socket of each pair earthed?
Each connection is a labelled pair of 4 mm sockets with one side earthed, giving a common reference so signals can be taken to a loudspeaker, vibrator or oscilloscope with standard 4 mm leads.
Is Science Lab Supplies the manufacturer or a trader?
Its maker is Science Lab Supplies itself: the unit is produced in the company’s own factory at Saha, Ambala, India, so each quotation is issued by the manufacturer rather than passed through an agent.
How is the unit switched on and protected?
An illuminated on/off switch on the rear panel sits next to a fused mains inlet, keeping the front panel clear for the frequency controls, the LED display and the 4 mm socket pairs.
