Product Code : SCL-CE-12520
Indian Lab Suppliers supplies the QPSK, OQPSK, DQPSK Modulator and Demodulator (Product ID: 12520), part of the Communication Equipment range under Laboratory equipment, an extensive hands-on trainer covering Quadrature Phase Shift Keying, Offset Quadrature Phase Shift Keying and Differential Quadrature Phase Shift Keying, with the modulator and demodulator built on the same board.
Note on naming and scope: our catalog also includes the QPSK Modulation/Demodulation Trainer (Product ID 12571); please confirm the exact model with our team. That trainer is a simpler, dedicated QPSK-only board built on discrete ICs (555/7490/74165) with a fixed 200 kHz clock; this trainer is a comprehensive, DDS-based platform covering QPSK, OQPSK and DQPSK with variable line-speed rates, 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 lets students study QPSK, OQPSK and DQPSK modulation and demodulation with variable bit pattern and frequency, including 2-bit I-channel/Q-channel encoding and decoding, offset encoding and decoding for OQPSK, differential encoding and decoding for DQPSK, and the integrator and comparator block used at the demodulator end, using an on-board DDS-based carrier generator.
Key Features
Personalized learning platform · on-board four variable line-speed rates and single-bit data pattern · on-board DDS-based carrier generator · SMD LED indicators · compact, book-like form factor for hands-on learning.
