Installing the 87130A Attenuator/Switch Driver

Connecting Switch Drivers to Switches and Attenuators

Connect attenuator cables using a Viking connector and a ten pin connector. A typical connection of four section attenuators is shown below.

When connecting attenuators

•A CLOSE position should add attenuation.

•An OPEN position should remove attenuation.
