QAM/DQAM Demodulation Trainer Manufacturer,Supplier and Exporter in India

Product Code : SCL-CE-12584

Indian Lab Suppliers supplies the QAM/DQAM Demodulation Trainer (Product ID: 12584), part of the Communication Equipment range under Laboratory equipment, a dedicated demodulation-side trainer for recovering QAM and DQAM carrier signals using PLL and envelope-detector demodulation.

Note on pairing: this trainer is the demodulation (receiver) counterpart to our QAM/DQAM Modulation Trainer (Product ID 12583), which covers the modulation (encoder) side of QAM and DQAM with Tribit encoding; together the two demonstrate a complete QAM/DQAM modulation-demodulation link. Please confirm with our team whether you need this trainer alone or as a matched pair with Product ID 12583.

Quick Answer

This trainer lets students study QAM and DQAM carrier demodulation using PLL and envelope-detector demodulation, decoding Tribit (I, Q & C) data back to NRZ-L format with differential decoding of the I and Q bits, regenerating the receiver clock using a PLL method, and using switch-selectable faults to study circuit-fault effects.

Key Features

Advanced digital communication trainer for understanding digital demodulation techniques · functional block diagrams provided onboard for teaching and training · test points provided to visualize signals on an oscilloscope · receiver clock generated by PLL method · QAM/DQAM demodulation using PLL and envelope detectors · Tribit (I, Q & C) decoded data with differential decoding of I & Q bits, output as NRZ-L · switch faults provided onboard to study different fault effects on the circuit · block description screen-printed on the glassy epoxy PCB for interconnections · all interconnections made using 2mm banana patch cords · all ICs mounted on IC sockets · bare-board-tested glass epoxy SMOBC PCB.

Indian Lab Suppliers is an India-based laboratory equipment manufacturer and exporter supplying this QAM/DQAM Demodulation Trainer alongside its broader Communication Equipment catalog, with documentation such as a Certificate of Origin available on request for institutional and export orders.

Frequently Asked Questions

Does this trainer need to be bought with the QAM/DQAM Modulation Trainer?
Not necessarily, but the two form a matched encoder/decoder pair; please confirm with our team whether you need this trainer alone or together with our QAM/DQAM Modulation Trainer (Product ID 12583) to demonstrate a complete link.

How is QAM/DQAM demodulated on this trainer?
The trainer uses a combination of PLL (phase-locked loop) and envelope-detector methods to recover the carrier and demodulate the Tribit-encoded I, Q and C data back to NRZ-L format.

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.
