4 Introduction
This Setup Guide is a systematically structured guideline to assist you with the set-up of your Meinberg product.
ADU/GPS-1-12 is an antenna splitter which distributes the intermediate frequency of 35.4 MHz coming from a
Meinberg GPS antenna to up to 12 Meinberg GPS reference clocks via individual coaxial antenna connections.
The ADU/GPS-1-12 must be mounted inside a building and connected to a Meinberg GPS antenna via a
coaxial cable (included when ordering a GPS antenna).
The ADU/GPS-1-12 system requires an externally supplied voltage to supply the connected antenna for op-
eration. The voltage is supplied via the master output, which must be connected to a running reference clock
(e.g. in an IMS system).
The system is suitable for retrofitting existing Meinberg GPS systems. The following GPS reference clocks are
suitable for use with ADU/GPS-1-12:
•IMS GPS reference clocks (e.g. IMS-GPS182, GNS181-UC)
•GPS slot cards (e.g. GPS180PEX)
•GPS top-hat rail systems (e.g. GPS180XHS)
Older reference clocks are also supported:
•GPS163
•GPS164
•GPS165
•GPS167
•GPS168
•GPS169
•GPS170
Information:
The GPS166 is not supported.
Manual Revisions
Meinberg products are subject to ongoing development even after their market release, with new features
and enhancements added on a regular basis. Meinberg also revises its product manuals to account for these
feature updates.
