Enable the radio’s PL/DPL squelch mode and fully open the squelch control (minimum setting or fully
counter-clockwise on many radios). In the RF Zone gradually raise the RF output level until the receiver
just breaks or opens the squelch. Refer to the radio’s service manual and determine if any adjustments
or repair are needed.
4.3 Cable Fault Testing
The R8100 Cable Fault Locator is used with the Cable Fault Option Kit to determine distance to a fault or
termination mismatch in RF cables. The kit contains a resistive RF power splitter, a 50 Ohm load, and
two male BNC cables for connecting the splitter to the R8100 analyzer. Figure 5.3-1 shows the
connections to the analyzer.
