Agilent N7781BD
Introduction
The Agilent N7781B is a compact high-speed polarization
analyzer that provides comprehensive capabilities for analyz-
ing polarization properties of optical signals. This includes
representation of the state of polarization (SOP) on the
Poincaré sphere (Stokes parameter). The on-board algorithms
together with the on-board calibration data ensure highly
accurate operation across a broad wavelength range. The Agi-
lent N7781BD also contains a windows based computer unit
which allows operation independent from external PCs.
Due to its real time measurement capability (1 MSamples/s),
the instrument is well suited for analyzing disturbed and fluc-
tuating signals as well as for control applications requiring
real time feedback of polarization information.
Analog data output ports are provided, for example for
support of control loops in automated manufacturing test
systems.
The provided analysis software allows a comprehensive
analysis of the obtained measurement data.
