AGILENT N4391A Optical Modulation Analyzer


General description of the used AGILENT N4391A for sale.
The Keysight N4391A Optical Modulation Analyzer offers most sophisticated signal processing algorithms with highest flexibility. The analysis software is based on the industry standard Keysight Vector Signal Analysis (VSA) software with extensions for the optical requirements like dual polarization data processing. This analysis software is the work horse in RF and mobile engineering labs and offers all tools needed to analyze complex modulated (or vector modulated) optical signals. It provides a number of parameters that qualifies the signal integrity of your measured signal. The most common one is the normalized geometric error of the Error Vector Magnitude (EVM) of up to 4096 symbols.
