QPSK/DQPSK Demodulation Trainer Manufacturer,Supplier and Exporter in India

Product Code : SCL-CE-12581

Indian Lab Suppliers supplies the QPSK/DQPSK Demodulation Trainer (Product ID: 12581), part of the Communication Equipment range under Laboratory equipment, a dedicated demodulation-side trainer for recovering QPSK and DQPSK carrier signals using PLL-based receiver clock regeneration.

Note on pairing: this trainer is the demodulation (receiver) counterpart to our QPSK/DQPSK Modulation Trainer (Product ID 12580), which covers the modulation (encoder) side of QPSK and DQPSK; together the two demonstrate a complete QPSK/DQPSK modulation-demodulation link. Please confirm with our team whether you need this trainer alone or as a matched pair with Product ID 12580.

Quick Answer

This trainer lets students study QPSK and DQPSK carrier demodulation, decoding the Dibit Pair (I & Q) data 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 · Dibit Pair (I & Q) data format with differential decoding · receiver clock generated by PLL method · QPSK and DQPSK carrier demodulation · 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.

Key Specifications

Note: the source specification lists this trainer's carrier demodulation techniques as "DPSK Demodulation, DQPSK Demodulation" — normalized here to "QPSK" consistent with the product name and the Dibit Pair (I & Q) data format documented above (matching the same normalization applied to the paired QPSK/DQPSK Modulation Trainer); verify with our team before ordering if you require confirmation of the exact demodulation set.

Scope of Supply

QPSK/DQPSK Demodulation Trainer unit · attractive enclosure · set of 2mm patch cords for interconnections · user's manual with sample experiments.

Where This Is Used

This trainer is used in electronics and communication engineering education for hands-on study of QPSK and differential QPSK demodulation, complementing our broader Electronics Lab Equipment and Engineering Lab Equipment ranges.

Why Buy from Indian Lab Suppliers

Indian Lab Suppliers is an India-based laboratory equipment manufacturer and exporter supplying this QPSK/DQPSK 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 QPSK/DQPSK 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 QPSK/DQPSK Modulation Trainer (Product ID 12580) to demonstrate a complete link.

How is the receiver clock recovered on this trainer?
The receiver clock is regenerated using a PLL (phase-locked loop) method, allowing the Dibit Pair (I & Q) data to be correctly sampled and differentially decoded.

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.
