Seamless Software Integration
Optical-LinQ is an intuitive and fully integrated software package for analysis of optically modulated signals. It runs entirely within the user interface of the LabMaster 10Zi-A. No other OMA on the market offers such integrated control of both oscilloscope and coherent receiver.
Optical-LinQ provides fully automated control of the IQS receiver, phase recovery algorithms, polarization demultiplexing, as well as an exhaustive number of modulation analysis displays and parameters.
Custom DSP Algorithm Validation
Test and validation of digital signal processing (DSP) algorithms is a vital part of the transceiver development. OpticalLinQ is equipped with built-in DSP algorithms such as CMA, MMA, Viterbi & Viterbi for you to use as tested reference algorithms. And the custom code integration feature lets you use and validate your own algorithms in MATLAB format.
