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

Product Code : SCL-CE-12580

Indian Lab Suppliers supplies the QPSK/DQPSK Modulation Trainer (Product ID: 12580), part of the Communication Equipment range under Laboratory equipment, a dedicated modulation-side trainer for studying QPSK and DQPSK carrier modulation using a four-phase 500 kHz carrier generator.

Note on naming and scope: this trainer covers the modulation (encoder) side only, with no demodulation/receiver section onboard. It differs from our QPSK Modulation/Demodulation Trainer (Product ID 12571, simple discrete-IC QPSK-only board with both modulator and demodulator) and from our QPSK, OQPSK, DQPSK Modulator & Demodulator (Product ID 12520, comprehensive DDS-based platform covering QPSK, OQPSK and DQPSK with both modulator and demodulator). Please confirm the exact model with our team if you need a full modulator/demodulator pair.

Note on pairing: this trainer is the modulation (encoder) counterpart to our QPSK/DQPSK Demodulation Trainer (Product ID 12581); 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 12581.

Quick Answer

This trainer lets students study QPSK and DQPSK carrier modulation using a synchronized four-phase 500 kHz carrier generator (0°, 90°, 180°, 270°), a Dibit Pair (I & Q) data format with differential encoding of the I and Q bits, an 8-bit variable NRZ-L data simulator clocked at 250 kHz, and switch-selectable faults for studying circuit-fault effects; it does not include a demodulation section.

Key Features

Advanced digital communication trainer for understanding digital modulation techniques · functional block diagrams provided onboard for teaching and training · test points provided to visualize signals on an oscilloscope · onboard synchronized four-phase 500 kHz sine wave generator with amplitude adjustment · Dibit Pair (I & Q) data format with differential encoding · onboard crystal-controlled pulse generator (BIT, BIT Clock, Word Clock) · onboard 8-bit variable NRZ-L pattern data simulator · QPSK and DQPSK carrier modulation · 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 modulation techniques as "QPSK modulation, DQPSK modulation" — consistent with the product name and the Dibit Pair (I & Q) data format documented above; verify with our team before ordering if you require confirmation of the exact modulation set.

Scope of Supply

QPSK/DQPSK Modulation 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 modulation, 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 Modulation 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 include a demodulator?
No, this trainer covers only the modulation (encoder) side of QPSK and DQPSK. For a board that includes both modulator and demodulator, see our QPSK Modulation/Demodulation Trainer (Product ID 12571) or our QPSK, OQPSK, DQPSK Modulator & Demodulator (Product ID 12520).

What is the difference between QPSK and DQPSK on this trainer?
QPSK encodes each dibit (2 bits) directly as one of four carrier phases, while DQPSK differentially encodes the I and Q bits so phase changes, rather than absolute phase, carry the data.

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.
