Which tool is commonly used to test cable signal strength?

The use of a digital signal meter is essential in testing cable signal strength effectively. This tool measures various signals transmitted through cable systems, providing crucial information on signal quality, strength, and performance metrics. It can assess the amplitude of the signal at different frequencies, enabling technicians to determine if the signal is within acceptable limits for optimal service delivery.

In contrast, a voltmeter primarily measures electrical voltage, which may not directly correlate to the quality of a cable signal. A cable cutter and a coaxial stripper, while useful in the installation and maintenance of cables, do not serve the purpose of measuring signal strength; they are more focused on manipulating or preparing cables for connections rather than testing their performance. Therefore, the digital signal meter stands out as the specialized tool needed for the task of assessing cable signal strength in a field technician's toolkit.
