3.2.4.1  Active Divider Unit (ADU)

The Active Divider Unit (ADU) is used for amplifying the received Rx signals. The Rx sig-

nals are distributed by the ADU and forwarded to the respective Channel Units (CHU).
The number of ADUs depends on the number of receiving antennas (Rx antennas). One

ADU is required for every Rx antenna.
This component features an antenna connection at the front side with which an external

antenna coupling system can be connected, refer to 

Ä

 Chapter 3.2.1 “Connection and

control panel” on page 31

.

The following figure shows the front view of the ADU. The following table describes it in

detail.
