Frequency Modulation/Demodulation Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-CE-12542
Indian Lab Suppliers supplies the Frequency Modulation/Demodulation Techniques Trainer (Product ID: 12542), part of the Communication Equipment range under Laboratory equipment, a block-wise modular training board covering three FM modulator circuits and six FM demodulator circuits for comparative study, requiring an external oscilloscope.
Note on naming: this board's name is very close to two other trainers in our range, so please confirm the exact model with our team. It is a comprehensive platform offering three modulator circuits (reactance, varactor, and VCO/IC-XR2206-based) and six demodulator circuits (detuned resonant, quadrature, Foster-Seeley, ratio, and two phase-locked-loop variants based on IC HEF4046 and IC LM565), across 40 test points and 12 switched faults. This differs from our Advanced Frequency Modulation and Demodulation Trainer (Product ID 12541, two modulators, five demodulators, 78 test points, 8 faults) and is a substantially more elaborate platform than our classic-era Frequency Modulation and Demodulation Trainer (Product ID 12524, single slope-detector scheme).
Quick Answer
This trainer lets students study frequency modulation using reactance, varactor and VCO-based (IC XR2206) modulator circuits, and compare six FM demodulation techniques — detuned resonant, quadrature, Foster-Seeley, ratio, and two phase-locked-loop detector variants (IC HEF4046 and IC LM565) — while investigating frequency deviation, modulation index, and the effect of noise on FM detection.
Key Features
Functional blocks with self-explanatory waveforms and technical details marked on the board · onboard audio oscillator, frequency modulators/demodulators, mixer/amplifier, amplitude limiter and filter circuits · LED indication for signal flow and selection · more than 35 test points · 12 switched faults for troubleshooting · optional interactive analog-communication curriculum software covering Fourier analysis, AM/DSB-SC/SSB, FDM, FM, pulse modulation, PLL and superheterodyne receivers · a digital storage oscilloscope is available as an optional accessory.

Frequently Asked Questions
How does this differ from your other FM trainers?
This is our most comprehensive FM platform, offering three modulator circuits and six demodulator circuits (including two different PLL-based designs) for direct comparison. Please confirm with our team which of our FM trainers best fits your curriculum requirement.
Does this trainer include the oscilloscope needed for the experiments?
No, an oscilloscope is required as separate apparatus; a digital storage oscilloscope is available as an optional accessory.
Do you supply this equipment for institutional or export orders outside India?
Yes. Indian Lab Suppliers quotes equipment for institutional and tender buyers across export markets — see the Tenders page for documentation requirements.
