Optical Complex Spectrum Analyzer

APEX Technologies starts to deliver its AP264XB Optical Complex Spectrum Analyzer (OCSA), which can be used as an optical modulation analyzer (OMA) and as an optical spectrum analyzer (OSA).  
As an OMA, it can measure chirp, phase, alpha parameter or pulse shape as a function of time. 
Furthermore, it can display constellation, phase eye diagram, intensity eye diagram, EVM.  
It is also capable of measuring any modulation format and any baud rate cycling signal modulated with a PRBS pattern or long pattern. Its measurement speed is ~1 Hz. It can separately and simultaneously measure two polarization axes and analyze Pol-Mux modulated formats.
As an OSA, the equipment combines high wavelength bandwidth resolution filter 0.04 pm (5 MHz), high wavelength accuracy +/- 3 pm and high dynamic range 83 dB.
