QPSK/DQPSK Demodulation Kit Manufacturer,Supplier and Exporter in India
Product Code : EL-PET-10219
Jlab Export is a leading QPSK/DQPSK Demodulation Kit Manufacturer,and suppliers in India
QPSK/DQPSK Demodulation Kit (code EL-PET-10219) is a digital communication training kit for the receive side of a quadrature phase shift keying link. It demodulates QPSK and DQPSK signals, works with I and Q dibit pairs and differentially encoded bits, and decodes the result back to NRZ-L data. Jain Laboratory Instruments Pvt Ltd, trading as JLab, manufactures it in Ambala, India.

What Is the QPSK/DQPSK Demodulation Kit Used For?
Recovering data from a four-phase carrier means separating the in-phase and quadrature components and keeping the timing in step with the transmitter. This kit lets students study that receive chain for both QPSK and DQPSK.
Frequently Asked Questions
How is a QPSK signal demodulated?
The received signal is multiplied by in-phase and quadrature reference carriers, and each product is low-pass filtered to give the I and Q bit streams. Each I and Q pair is then put back together as two consecutive bits of the serial data.
Why is the clock generated with a PLL?
The I and Q streams must be sampled at the right instant in every symbol, which needs a bit clock locked to the incoming signal; a phase-locked loop derives that clock from the received data.
How does it relate to the QPSK/DQPSK Modulation Kit?
That kit is the transmit side, using the same NRZ-L format, I and Q dibit pairs and differential encoding. Both can be quoted on one enquiry.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of electronics and communication trainers, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The kit is made at JLab’s own works and not bought from a trader, so colleges, dealers and importers deal with the factory directly, including for repeat orders and spares. JLab exports worldwide and ships to buyers in every region — for example Slovakia in Eastern Europe, Iceland in Northern Europe, Jordan in the Middle East, Australia in Oceania and Angola in Central Africa.
