Frequency Shift Keying Modulation and Demodulation Manufacturer,Supplier and Exporter in India
Product Code : EL-CT-1500
Jlab Export is a leading Frequency Shift Keying Modulation and Demodulation Manufacturer,and suppliers in India
Frequency Shift Keying Modulation and Demodulation (code EL-CT-1500) is a digital communication trainer for generating a frequency shift keyed (FSK) output and demodulating it again. Its built-in IC regulated ±12 V and 5 V supplies are connected internally, so the board works directly from the mains. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the FSK Modulation and Demodulation Trainer Used For?
Frequency shift keying sends binary data by switching the carrier between two frequencies, one standing for a binary one and the other for a zero. Because the information is carried in frequency rather than amplitude, FSK copes well with amplitude noise, which is why it was used in early dial-up modems, radioteletype and caller-ID signalling. The receiver’s job is to decide which of the two frequencies is present at each moment and turn that decision back into a data stream, and the trainer lets students follow both halves of the process on an oscilloscope.
JLab’s ASK and PSK trainers, linked below, cover the other two basic keying methods. The operating instructions give the object, theory, design procedure, report suggestions and book references for the FSK experiments.
What to Specify When Ordering
- Quantity — the number of FSK trainers for the digital communication lab.
- Mains supply — the board is built for 230 V ±10%, 50 Hz AC; check this against the supply where it will be used.
- Other keying trainers — the ASK, PSK and DPSK boards below are separate items that can be added to the same enquiry.
Frequently Asked Questions
Which ICs make up the circuit?
A quad op-amp IC, a decade counter IC, a timer IC, a 4-bit binary counter IC and a quad 2-input NAND gate IC, together with other electronic components on the board.
What do the two potentiometers adjust?
One varies the FSK input and the other is the demodulator adjustment, so the modulator input and the receiving side can be set up independently during the experiment.
How does FSK compare with ASK and PSK?
All three key a carrier with binary data. ASK switches its amplitude, FSK its frequency and PSK its phase. ASK is the simplest but the most affected by amplitude noise; FSK is more robust at the cost of extra bandwidth; PSK gives the lowest error rate of the three for a given signal-to-noise ratio but needs a phase reference at the receiver.
What else does the experiment need?
A 20 MHz cathode ray oscilloscope, which is a separate item, for viewing the waveforms; patch cords are provided with the trainer. JLab’s Dual Trace Oscilloscope, linked below, can be quoted with it.
What should an export enquiry include?
The number of trainers, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling requirements, and the tender reference if there is one.
Who manufactures this FSK trainer?
JLab, the trading name of Jain Laboratory Instruments Pvt Ltd, makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of electronics and communication trainers and other laboratory equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The FSK trainer is built in JLab’s own works instead of being bought from a trader, so institutions, dealers and importers order it directly from the maker, with repeat orders and spares handled the same way. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise. JLab exports worldwide and ships to buyers in every region — for example the UAE in the Middle East, Sri Lanka in South Asia, Ethiopia in East Africa, Mexico in North America and Brazil in South America. Details for tender buyers are on the JLab lab tenders page.
