Tools Required
You need a flat screw driver and a TORX No. 362 screw driver. A TORX screw driver is attached to
the shipment.

Each of the mainframes is equipped with an Agilent E4805A Central Clock Module. Use the delivered
clock distribution cables (p/n E4805-61601, the cables are already connected to the clock module in
the Extender mainframes) to connect from one Agilent E4805A module in one mainframe to the other
Agilent E4805A module in the other mainframe. Up to two additional mainframes can be connected.
It is necessary to unplug the Agilent E4805A Central Clock Module from the Master mainframe, open
the side panel and connect the flat cable from Extender 1 and Extender 2 into the connectors on the
main board of the module.
1. In the Master mainframe, disconnect all clock distribution cables to the Agilent E4841A or
E4861A modules going from the Central Clock module of the Master mainframe.
