Checking signal strength is crucial in troubleshooting video services because it directly impacts the quality of the video feed a customer receives. Poor signal quality can lead to various issues, including pixelation, freezing, or complete loss of service. When a technician measures the signal strength, they can determine whether the problems being experienced are caused by inadequate signal levels, which may stem from several factors such as environmental interferences, issues with the provisioning of the service, or faults in the physical connections.

By establishing if signal quality is poor, technicians can take appropriate corrective actions, such as adjusting antennas, repositioning equipment, or checking for line impairments. This is fundamental to ensuring a reliable video service for customers, as adequate signal strength is essential for delivering high-quality audiovisual content.
