What is the maximum ingress level that can still pass on the meter?

The correct answer relates to the acceptable levels of ingress, which is the unwanted signal that enters a cable system. For a properly functioning cable system, maintaining optimal signal quality is essential, and excessive ingress levels can lead to interference that impacts service.

At -35 dBmV, the level represents a threshold that, while not optimal, can still allow for signal passage without severely degrading the quality of the output signals. This level indicates a balance where some interference is present, but it is within a range where the signal can still be processed effectively by the equipment.

It’s important to understand that levels lower than this, like -40 dBmV or -45 dBmV, would indicate a higher tolerance of ingress, but the goal is to minimize unnecessary signal degradation. Thus, -35 dBmV serves as a crucial benchmark in signal integrity for cable systems. Being trained to recognize and manage these ingress levels ensures technicians can maintain a high-quality service for users while effectively diagnosing and addressing potential issues in the field.
