2.2 Run Sweep Test
Before installing the Repeater, check mechanical assembly of all RF
connectors, run a sweep test of the RF cables and record the cables loss.
Perform the sweep test using a Site Master analyzer or a Network Analyzer.
•
Perform open/short tests on the distribution RF cables.
• Record the following parameters for each RF cable:
o
Insertion loss of the cable
o
Return loss (VSWR)
• If you detect a fault in any of the cables, repair it and re-check until all the
cables are good.
NOTE: Record the information for reference in Appendix D. This
information is used during the setup procedure.
