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 is intended for sound, waves and AC practicals in school and college physics laboratories. The unit is manufactured by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and sold directly to schools, colleges, tender contractors and distributors.
Specifications
The generator offers three waveforms, a switched frequency range with continuously variable fine adjustment, and an LED frequency readout. Every connection is made through a pair of labelled 4 mm sockets, one of each pair earthed, and the unit sits in a powder-coated metal case with a fused mains inlet.

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. Its three waveforms also let teachers compare wave shapes on an oscilloscope in school physics and college electronics classes.
- Class 9 sound: linking displayed frequency to pitch.
- Class 11 waves: resonant frequencies of strings and springs.
- Comparing sine, square and triangular waves on an 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).

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?
Science Lab Supplies is a science apparatus manufacturer in India. This unit is produced in the company's own factory at Saha, Ambala, so your quotation is issued by the maker rather than passed through an agent.
What output power does the amplifier give?
The product description does not state the output power or frequency limits. Tell us the load you plan to drive through the contact page, and the figures will be confirmed with the quotation.
Related Signal Sources and Transducers
The unit produces the signal, but most experiments also need a device that responds to it and an instrument that displays it. The four items below cover an alternative source, a vibrator, a display and a pick-up coil, and can all share one quotation.
- Bench Signal Generator — sine and square source, 5 Hz to 50 kHz.
- Vibration Generator — fuse-protected coil-and-magnet vibrator.
- Oscilloscope — colour-screen instrument for viewing waveforms.
- Search Coil — 3300-turn coil for detecting alternating magnetic fields.
