How To Use A Coax Cable Tester

Coaxial cables are widely used in today’s communication systems. They are used to transmit signals from one device to another and provide high-quality visuals and sounds. A coax cable tester is a tool used to test the continuity and quality of a coaxial cable.

A coax cable tester has a transmitter and a receiver. The transmitter generates a signal that is sent through the coaxial cable under test, and the receiver detects the signal at the other end. The results of the test will indicate whether the cable is functioning correctly or if there are any defects.

So, let's take a look at how to use a coax cable tester step by step:

Step 1: Identify the type of connector

Before testing a coaxial cable, you need to determine the type of connector that is used for the cable. The most common types of connectors are F-type connectors, BNC connectors, and N-type connectors. Different testers may require different types of connectors, so make sure that you have the right adapter.

Step 2: Connect the transmitter

Connect the transmitter to one end of the coaxial cable to be tested. Make sure that the connector is attached correctly to avoid any damage to the cable. Turn on the transmitter.

Step 3: Connect the receiver

At the other end of the cable, connect the receiver and attach it to the correct adapter that corresponds with your connector type. Turn on the receiver.

Step 4: Check the signal

Verify that a good signal is being transmitted through the cable. Ensure that the transmitter and the receiver lights are working correctly. A good signal will show consistent light patterns across both devices.

Step 5: Test for continuity

Test for continuity by checking for a solid light on the receiver. A solid light indicates that the cable has continuity and is not damaged. If no light comes on, the cable has a break or short.

Step 6: Test for shielding

Test for continuity between the shield part of both connectors. Both the transmitter and the receiver should indicate the continuity of the shield.

Step 7: Test for impedance

Test for impedance by measuring the resistance of the cable. This value should match the specifications of the cable.

Step 8: Interpret the results

Interpret the results of the tests. If all tests passed, the cable is in good condition. If any of the tests failed, the cable needs to be repaired or replaced.

In conclusion, a coax cable tester is a valuable tool when working with coaxial cables. It ensures that the cable is functioning correctly and can help detect any issues that need to be addressed. When using the tester, make sure to follow the instructions carefully and use the right adapter for your specific connectors. By doing so, you can save time, money, and prevent unnecessary headaches.
