Test preparation
Set up the equipment to perform the pre-power tests. Figure 81 is an example to show how
this is done. In this example, there is a short length of cable from the analyzer (in place of
the CMU) to the first LPU, a length of cable ‘y’ from the first LPU to the second LPU (at
the top of the tower) and a short length of cable from the second LPU to the ODU (0.7m
long supplied in the accessory kit).

Perform these tests in conjunction with the test equipment manufacturer’s instructions.
