How To Test Coaxial Cable Signal

Coaxial cable is widely used to transmit audio, video, and data signals over a long distance. It is important to test the coaxial cable signal to ensure that the transmission is of high quality and that there is no interruption in the signal. This article will guide you on how to test the coaxial cable signal.

Equipment required

- Coaxial cable tester

- Connectors

- Coaxial cable stripping tool

Steps to test coaxial cable signal

1. Disconnect the coaxial cable from the device or equipment it is connected to.

2. Inspect the cable and connectors for any damage or wear and tear. It is important to fix any issues before proceeding with the testing.

3. Strip the coaxial cable at both ends, exposing the inner conductor and shielding. Use the coaxial cable stripping tool for an exact cut.

4. Attach one end of the cable to the coaxial cable tester. Make sure it is securely attached to the connector.

5. Switch on the cable tester and follow the instructions on the screen to adjust the settings for the cable type you are testing.

6. Check the reading on the tester. A good signal reading should be between -10 dB to +10 dB. If the reading is outside of this range, then there may be an issue with the cable.

7. Next, test the other end of the coaxial cable by attaching it to the tester.

8. If the reading is still out of range, then check the connectors. Undo the connections and reattach them ensuring they are tightly secured.

9. If the reading is still out of range, then you may need to replace the cable or the connectors.

10. Once you have completed testing the cable, reattach it to the device and ensure that it is working properly.

Conclusion

In conclusion, testing the coaxial cable signal is important to ensure that you have a good quality transmission. By following the steps outlined above, you can easily test your coaxial cable and identify any issues that need to be fixed. Regular testing of coaxial cables can help to prevent signal loss and other issues that may occur during transmission.
