Keysight (Agilent) N4391A Optical Modulation Analyzer

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.

Bit Error Ratio (BER)
Bit Error Ratio (BER) is the ratio of errors caused by the number of bits in a data stream that have been altered due to noise, interference, distoriton or bit synchronization errors.

Flatness
Variation of insertion loss on the passband of an optical device.

Polarization Dependent Loss (PDL)
Polarization Dependent Loss is the difference between the maximum and minimum values of loss due to the variation of the polarization states of light propagating through a device. PDL is expressed in decibels. Calculated by; PDL = 10 log10 (Ep/Es), where EP and ES are the measured diffraction efficiencies for P- and S-plane polarized incident light, respectively.

Return Loss (RL)
Return Loss (RL) is the ratio of the incident power to the reflected power expressed in dB. RL = 10log (Pin/Pback)

Wavelength Resolution
Wavelength Resolution is the smallest possible displayed wavelength increment/decrement.
