COAX Cable Field Calibration and Testing<br />
TROUBLESHOOTING COAX CABLING<br />
Always use high quality connectors and tools to properly terminate COAX network. In<br />
case of a cable fail, look for the following cases:<br />
‣ FAULTY TERMINATION - Make sure you have properly separated the center<br />
conductor from the shield.<br />
‣ CABLE SHORT - This could occur from improper termination both at near-end<br />
and far-end. In case of a SHORT, look for the Resistance value on the tester. A<br />
zero (0) – Ohm resistance value will suggest the fault is at the near-end of the<br />
cable, while a ~ 20 – Ohm value will suggest the fault is at the far-end.<br />
‣ CABLE OPEN - A common case. To diagnose this situation, look at the cable<br />
length measurement. A zero (0) cable length will suggest a fault at the nearend.<br />
‣ USE of TDR to Diagnose Problem - The <strong>LANTEK</strong> build-in copper TDR is a good<br />
tool to identify the location of the fault and distance of the fault. Refer to the<br />
TDR operation in this manual for more details.<br />
