Stand-alone Software for Analysis of Complex Modulated Optical Signals

The analysis software from the N4391A optical modulation analyzer can be used on your PC without any instrumentation. It offers all the analysis capabilities of the N4391A including its advanced signal processing algorithms for complex modulated optical signals. Use this software to process and analyze raw data stored as .sdf, .mat or .csv files from N4391A or N4392A measurements. This capability allows you to work with the data as if you would work directly in front of the instrument. It is an excellent tool for developing your own signal processing algorithms and testing them off-line, together with your MATLAB compiler. In addition, this software is an effective tool for learning basic and advanced concepts of complex optical modulation, based on stored files.

The software can be extended with an additional license to provide control of one or two Keysight Infiniium oscilloscopes.
