What type of meter is used to measure signal levels in cable installations?

The correct choice is a cable meter, which is specifically designed for measuring signal levels in cable installations. Cable meters provide vital information about the quality and strength of the signal traveling through the cables, allowing technicians to troubleshoot issues and ensure optimal performance. These meters can also measure various frequencies and provide data on parameters such as signal strength, cable loss, and noise levels.

Using a cable meter is essential in the field because it directly addresses the needs of maintaining and installing coaxial and fiber optic cables, which are common in cable services. This specialized approach offers features that are tailored for RF (radio frequency) measurements, setting it apart from other types of general measurement tools. In contrast, other options like ohmmeters, multimeters, and voltmeters measure electrical properties such as resistance and voltage but lack the specific capabilities needed for assessing signal quality in cable networks.
