What is a signal level meter primarily used for?

A signal level meter is primarily utilized to assess the quality and strength of a signal in telecommunications and broadcasting. Its main functions include measuring various parameters such as signal level, Modulation Error Ratio (MER), Bit Error Rate (BER), and noise level.

This capability allows technicians to evaluate the performance of a transmission system, ensuring that the signal strength is adequate for reliable communication and that the overall quality is maintained. Properly measuring these metrics helps in troubleshooting and optimizing signal distribution systems, which is essential for achieving high-quality service delivery in cable, satellite, and other communication technologies.

In contrast, options that mention boosting signal strength or calculating system latency do not align with the primary function of a signal level meter, which does not actively alter or enhance a signal but rather provides critical data for analysis and adjustment by technicians. Similarly, measuring electrical resistance is outside the scope of the functions associated with a signal level meter.
