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

Product Code : SCL-CE-12571

Indian Lab Suppliers supplies the QPSK Modulation/Demodulation Trainer (Product ID: 12571), part of the Communication Equipment range under Laboratory equipment, a compact discrete-IC trainer dedicated to Quadrature Phase Shift Keying, with the modulator and demodulator built on a single glass-epoxy PCB.

Note on naming and scope: our catalog also includes the QPSK, OQPSK, DQPSK Modulator & Demodulator (Product ID 12520); please confirm the exact model with our team. That trainer is a comprehensive, DDS-based platform covering three techniques (QPSK, OQPSK and DQPSK) with variable line-speed rates, 25 SMD LED indicators and 57 test points. This trainer is a simpler, dedicated QPSK-only board built on discrete ICs (a 555 clock generator, 7490 carrier generator and 74165 data generator) with a fixed 200 kHz clock and 100 kHz quadri-phase carrier, so the two differ mainly in scope and underlying technology.

Note on scope: for a modulation-only board (no demodulator) covering QPSK and DQPSK, see our QPSK/DQPSK Modulation Trainer (Product ID 12580).

Quick Answer

This trainer demonstrates QPSK modulation and demodulation using an onboard 555-based clock generator (200 kHz), a 7490-based carrier generator producing four quadri-phase 100 kHz outputs (0°, 90°, 180°, 270°), and a 74165-based data generator producing a switch-selectable simulated data stream at approximately 1 kb/s, feeding dedicated onboard QPSK modulator and demodulator circuit blocks.
