Bench Signal Generator
Product Code : LSK-PL-10279
Bench Signal Generator (SKU LSK-PL-10279) produces sine and square waves from 5 Hz to 50 kHz, at up to 8 V peak to peak and 1 W into 8 ohms. It suits sound lessons in schools and waves and electronics practicals in colleges and polytechnics. Science Lab Supplies makes the generator at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and its quotations go out from there to schools, colleges, contractors and distributors.
Specifications
Every rating of this sine and square wave generator has a row of its own in the table. In short, four switched ranges plus a fine control cover 5 Hz to 50 kHz, the amplitude runs from zero to 8 V peak to peak, and the signal leaves through two front-panel 4 mm sockets.

Applications and Experiments for the Bench Signal Generator
The generator can drive a small loudspeaker or a vibrator and feed test signals into circuits viewed on an oscilloscope. Its 5 Hz to 50 kHz span covers the audible range, making it a practical signal generator in the electronics lab as well as for sound, resonance and AC circuit work in schools and B.Sc. labs.
- Class 9 physics: pitch and frequency of sound through a loudspeaker.
- Class 11 waves: resonance and standing waves at a chosen frequency.
- B.Sc. and diploma labs: frequency response of RC circuits set up with a Resistance Substitution Box and a Capacitance Substitution Box.
- Comparing sine and square waves on an oscilloscope.
Standard Scope of Supply
The Bench Signal Generator is supplied as a single unit as described above, in its powder-coated metal case with front-panel 4 mm output sockets, an illuminated rear switch and a fused mains inlet. Loudspeakers, oscilloscopes and connecting leads are separate items that can be added to the quotation.
Packing, MOQ and Lead Time
Send the number required, whether one generator for a demonstration bench or several for student groups; the quotation sets out packing, delivery time and price for that quantity. Matching loudspeakers and vibration generators can be quoted alongside it on the same document.
Science Lab Supplies is registered as an exporter with an Importer-Exporter Code and can ship to buyers in Uganda, the UAE, Saudi Arabia, Oman, the Philippines and Nepal. A price for the generator can be requested by writing through the contact page, by saving it in the enquiry cart, or, for institutional purchasing, via the lab tender page.
Frequently Asked Questions
What waveforms and frequencies does it produce?
Sine and square waves from 5 Hz to 50 kHz, chosen with a four-position range switch and a fine control. Frequency accuracy is typically ±10%, adequate for teaching use.
Can it drive a loudspeaker?
Yes, for classroom use. The output delivers up to 1 W into an 8 ohm load, with the amplitude adjustable from zero to 8 V peak to peak, suitable for a small demonstration loudspeaker.
Is Science Lab Supplies the manufacturer or a trader?
The generator is assembled at the Science Lab Supplies works in Saha, Ambala, which makes the company its manufacturer, not a trading house. Your quotation, packing and dispatch all come from that same factory.
How is it powered?
It runs from the mains through a fused inlet on the rear panel, beside an illuminated on/off switch, leaving the front panel for the controls and output sockets.
