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.
