DQPSK and DP-QPSK
Typical DQPSK Test Configuration with PatternPro Instruments
DQPSK (Dual Quadrature Phase Shift Keying) and DP-QPSK (Dual-Polarization QPSK) testing requires programmable multi-channel signals that may be phase aligned according to the requirements of the application. In addition, flexible test systems that accommodate drive signal requirements for components such as Mach-Zehnder LN modulator drivers help enable a wide range of testing that covers components, modules, and systems.
The Picosecond Pulse Lab PatternPro line of instruments offers efficient and simple control of all of the parameters needed for QPSK testing, including channel-independent data patterns (user data or built-in PRBS), programmable data rate, adjustable signal parameters (amplitude, offset), and programmable phase/delay for pattern and bit alignment adjustments.
