Agilent N7785B Synchronous Scrambler Data Sheet Figure 1. N7785B-001 bench-top mainframe 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. www.DataSheet4U.com 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. An electrical trigger input can be used to synchronize the scrambler with external events.
