Measuring the Output Power Level
Uplink and downlink output power test ports are found on the directional
couplers (DC) at the MS and BS antenna connectors. These test ports are
marked TEST –30dB (see Figure 4-1) and are intended for measuring
using e.g. a spectrum analyzer.
The coupling is –30dB approximately. There is no directivity in these test
ports, i.e. both uplink and downlink signal can be measured.
Voltage Supply Testpoints
A number of voltage supply testpoints are available in the repeater.
These testpoints are named U7A - U7F for the 7V supply voltages and
U26 for 26V, 13V or 10V supply voltage (depending on the repeater type).
A standard multi-meter can be used on these testpoints.
The testpoints are found on the DIA board in the repeater cabinet. The
testpoint positions on the DIA board is detailed in the Board and Unit
Descriptions section in Chapter 5.
If the repeater is equipped with a second PSU, e.g. for combined
channel/band selective operation, the same set of testpoints are also found
on the cover DIA board.
Repeater Configuration
The repeater is now ready to be configured in accordance with the site
conditions and system performance requirements. Pay especial attention
to the antenna isolation described in the OMT32, User’s Manual.
