AS4000 SURVEY TOOL.
4. 1. Introduction
The survey tool provides for the efficient planning of CRU location at the Subscriber Terminal
(RNU). It may also be used as a tool for surveying the signal coverage area of a given Central
Terminal (RLT) e.g. along existing pole routes. It consists of a telescopic mast attached to a
tripod base, CRU, Drop Cable, and a Test Box. The mast is erected as near to a probable CRU
location as possible and is raised to the mounting height of the CRU. The CRU is panned to
assess the signal strength at that location. The test box gives a readout of the values of AGC and
Power Control readings that can be related to the levels recorded on the CRU calibration label.
Details of the position, height, and panning angle can then be recorded for use by the installer.
