Which tool measures signal strength in coaxial cables?

The digital signal level meter is specifically designed to measure the strength of signals transmitted through coaxial cables. This tool provides accurate readings of signal levels and helps technicians assess the performance of the coaxial cable system. By measuring the strength and quality of the incoming signals, a digital signal level meter assists in troubleshooting potential issues such as signal degradation or interference. This makes it an essential instrument for ensuring the proper functioning of coaxial cable installations.

In contrast, the other tools mentioned serve different purposes. A bandwidth analyzer is used to assess the frequency bandwidth of signals rather than their strength. A signal generator creates signals for testing and does not measure existing signals. Lastly, an oscilloscope visualizes electrical signals to analyze their waveforms but does not specifically measure signal strength in coaxial cables. Therefore, the digital signal level meter stands out as the appropriate choice for measuring signal strength in this context.
