Quadrature Error - Common impairments in coherent transmission systems

Engineers often face with challenges when analyzing the constellation diagrams of the coherent test signal. In this tutorial, we dive into the quadrature errors and learn a possible root cause. The main reasons behind these faults will also be mentioned for you to adjust the measurement setup and get the expected constellation diagrams.
