Keysight Technologies Inc. Optical Modulation Analysis Software
The Keysight N4391SALC is an Optical Modulation Analysis (OMA) software license for the N4391A OMA solution. This software enables advanced analysis of complex modulated optical signals, supporting formats such as QPSK and QAM. It provides comprehensive measurement capabilities including constellation diagrams, eye diagrams, error vector magnitude (EVM), and bit error ratio (BER) analysis. The N4391SALC software is designed for use in research, development, and manufacturing environments, offering automated test sequences, flexible data export, and compatibility with Keysights high-speed oscilloscopes and optical front-ends. It is essential for characterizing coherent optical transmitters and receivers.
