3.4 PRE-INSTALLATION NOTES
It may be useful to gain familiarity with the MDS Digital Radio Series via back-to-back bench
testing prior to final installation. We highly recommend installation of lightning protectors on the
ODU/SDIDU
TM
Interconnect Cable to prevent line surges from damaging expensive components.
Back-to-back bench testing prior to final installation is highly recommended in order to gain
familiarity with the product. The following additional equipment is required for back-to-back
testing:
•
Low-loss cables, N-male connectors on ODU interfaces.
•
Two inline RF attenuators, 30 dB each, rated for ODU frequency.
The SDIDU
TM
and ODUs must be configured in an operational configuration and set-up as shown
in
175H 172H
Figure 3-2. When equipment is connected in operational configuration, no errors should be
reported on the front panel.
