Introduction
The Agilent N7785B is a high-speed synchronous
scrambler. It contains a polarization controller plus
microcontroller- based driving circuitry. This unit can
operate in various modes:
As a synchronous scrambler, the device switches the
SOP of the output signal in a random (pseudo) way.
Switching of the SOP occurs within a few microseconds.
The SOP is stable for a predefined time until it again
switches to a new SOP.
An electrical trigger input can be used to synchronize
the scrambler with external events.
As an SOP switch the N7785B allows switching the
internal waveplates to user definable angles with very
high speed and repeatability.
As a traditional scrambler, the Agilent N7785B varies the
output SOP smoothly in a random/pseudo random way.
The unit does not contain any moving parts, and
therefore is robust and withstands even rough
environmental conditions.
All above-mentioned applications of the N7785B are
supported by Agilent’s PC software package which
comes with this instrument.
