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

Product Code : SCL-CE-12583

Indian Lab Suppliers supplies the QAM/DQAM Modulation Trainer (Product ID: 12583), part of the Communication Equipment range under Laboratory equipment, a dedicated modulation-side trainer for studying Quadrature Amplitude Modulation and Differential QAM using a four-phase 500 kHz carrier generator and Tribit (3-bit) data encoding.

Note on naming and scope: this trainer covers the modulation (encoder) side only, with no demodulation section onboard, and uses a simple discrete four-carrier design with Tribit (I, Q & C) encoding. It differs from our QAM Trainer (Product ID 12549), a comprehensive DDS-based platform covering QAM modulation and demodulation together with constellation-diagram viewing and digitally-selectable noise. Please confirm the exact model with our team if in doubt.

Note on pairing: this trainer is the modulation (encoder) counterpart to our QAM/DQAM Demodulation Trainer (Product ID 12584); 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 12584.

Quick Answer

This trainer lets students study QAM and DQAM carrier modulation using a synchronized four-phase 500 kHz carrier generator (0°, 90°, 180°, 270°), Tribit (I, Q & C) data encoding with differential encoding of the I and Q bits, a 24-bit variable NRZ-L data simulator (three 8-bit switch banks) clocked at 250 kHz, and switch-selectable faults for studying circuit-fault effects.

Frequently Asked Questions

Does this trainer include a demodulator?
No, this trainer covers only the modulation (encoder) side of QAM and DQAM. For a comprehensive platform covering both modulation and demodulation, see our QAM Trainer (Product ID 12549).

What is Tribit encoding on this trainer?
Tribit encoding groups three data bits (I, Q and C) per symbol, which the trainer maps onto one of the QAM/DQAM carrier states using the four-phase 500 kHz carrier generator.

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.
