Signal Generator
Product Code : LSK-PL-10277
Signal Generator (SKU LSK-PL-10277) is a function generator with a built-in 10 W power amplifier that drives a loudspeaker or vibration generator directly. Physics teachers use it for sound, waves and resonance lessons in schools and oscillation practicals in colleges. For basic use it needs only two controls: frequency and amplitude. Science Lab Supplies supplies this instrument from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The generator pairs a digital display with a speed-sensitive frequency control: turn it slowly to change the last digit, faster to move in larger steps. Its amplifier delivers more than 1 A at every frequency between 0.001 Hz and 100 kHz, and a USB port links it to a computer.

Applications and Experiments for the Signal Generator
The generator supplies a controlled alternating signal with enough power to move something: a vibration generator for standing waves, a loudspeaker for sound experiments, or any system being swept for resonance. It suits secondary school physics labs and college oscillation practicals equally well.
- Class 9 and 11 physics: frequency and pitch with a loudspeaker.
- Standing waves, using step mode to jump to harmonics.
- Resonance searches with linear or logarithmic sweeps.
- College labs: custom waveforms loaded over USB.
Standard Scope of Supply
The Signal Generator is supplied as a single instrument as described above, ready to drive a load directly. It connects to a computer through a standard USB cable; any leads, cables or accessories you want with it are listed item by item on the quotation.
Packing, MOQ and Lead Time
Quotations can cover one generator for a single lab or several for a school group or tender, and each one states the packing, delivery time and price for that quantity. A vibration generator or demonstration loudspeaker can go on the same quotation from this physics instruments supplier in India.
Science Lab Supplies holds an Importer-Exporter Code as a registered exporter and can ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman. Enquire through the contact page or the enquiry cart, or see the lab tender page for tenders.
Frequently Asked Questions
Does it need a separate amplifier?
No. The built-in 10 W amplifier drives loudspeakers and vibration generators directly, delivering more than 1 A at every frequency between 0.001 Hz and 100 kHz.
What do the sweep and step modes do?
Sweep mode runs through a range and speed you set, linearly or logarithmically, to find resonances. Step mode jumps to successive multiples of a fundamental frequency, useful for showing harmonics.
Who supplies the Signal Generator?
Science Lab Supplies supplies it from Ambala, India, with the rest of its physics range, and handles the quotation, packing and dispatch for single laboratories and larger orders alike.
Can it be connected to a computer?
Yes. Over USB it appears as a flash drive. Custom waveforms, such as ones built in a spreadsheet, can be saved to it, and sequences of settings programmed to run automatically.
Related Waves and Sound Equipment
Most wave experiments need a transducer to turn the signal into motion or sound, and an instrument to display it. These four Physics Lab items complete that chain alongside the generator and can share one quotation for a waves and sound bench.
