Which tool is used to measure the strength of a signal?

A signal strength meter is specifically designed to quantify the power of a signal received by a device. It provides a clear numerical value that indicates the strength of the signal, which is essential for determining whether it meets the required levels for optimal performance. This type of meter operates by measuring the amplitude of the signal and can be used across various communication technologies, including radio, television, and cellular networks.

While troubleshooting software is useful for diagnosing problems in a network and performing analyses, it does not directly measure signal strength. Similarly, a network analyzer primarily examines the performance and health of networks and captures traffic for analysis, rather than measuring signal strength directly. A cable tester is utilized to check the integrity of the cabling and its connections, but it does not provide a measurement of the signal strength itself. Therefore, using a signal strength meter is the most appropriate choice for the task of measuring signal strength.
