AS4000 Survey Tool TAD-002 605-0000-429 Issue 1.6. Date 1/9/99 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 following factors should be taken into account to determine the installation position for the CRU: a) The CRU should be installed as high as possible on the wall facing in the direction of the CT. Mounting height should normally be 5-7 metres above ground level. b) Inspect the suitability of the wall structure for the installation position of the CRU mounting.

AS4000 Survey Tool 605-0000-429 DLP-004 Issue 1.6. Date 1/9/99 PANNING THE CRU The following procedure will have to be completed before placing the AS4000 system into service. All results must be entered on the Survey Test Result form, see DLP-005. STEP 1. PROCEDURE CRU Characterisation The CRU has a characterisation label fixed to the CRU back plate. This label records factory measured readings of TX PC and RX AGC Volts for different set levels. 2.
PAGE 39
AS4000 Survey Tool 605-0000-429 DLP-004 Issue 1.6. Date 1/9/99 3. Power Control Recording 1. The voltage measured is a relative indication of the transmit power level: The lower the voltage the higher the output power level. This is only valid when the link LED is lit - only possible with TX enabled. 2. Check the label on the CRU to get an indication of the transmit signal strength from the characterised readings to ensure that the margins are consistent with the receive fade margins.
PAGE 40
AS4000 Survey Tool 605-0000-429 DLP-004 Issue 1.6. Date 1/9/99 7. If the PC value indicates a fade margin of less than 10dB. Use a second pan to accurately find the maximum for both AGC and PC. Pan slowly and limit the panning to approximately ± 15°from the initial position to prevent losing the link. If the link drops restore to an approximate maximum and repeat the panning process. Record the AGC and PV values again if different form first pan.
