Supporting single- or multi-carrier systems as well as 100G and 400G communications standards, 45 GHz optical modulation analyzer (OMA) tightly integrates with DPO70000SX 70 GHz ATI Performance Oscilloscope. This enables multi-channel digitization of complex modulation signaling for testing coherent optical transmitters, transmission systems, and receivers. Capable of dual-polarization coherent optical analysis up to 80 GBaud, OMA offers narrow linewidth lasers and supports OM-Series UI.
