Bench Testing
To aid system commissioning or to check the integrity of the equipment, the
Plessey
EasyReach link may be bench tested by bypassing the antennas, as
shown in Figure 6.
Units may only be connected with an attenuator exceeding 50 dB in the path
between antenna ports.
CAUTION
Do not connect the antenna ports of two units directly together. Damage of
both units will result.
