Shielding Effectiveness measurements can be performed with or without the affixing coaxial connectors removed from the measurement.
Why and when is important to carry out this test?
The shielding attributes of components in a CATV system are critical to system performance. Ingress and egress issues can have detrimental effects on the overall performance of the system from both regulatory and quality perspectives.
Ingress issues can cause problems with television picture quality, and the effective transfer of data by allowing spurious signal into the system.
Egress issues can allow signals captured in the system to leak out and possibly interfere with wireless
communications which utilize the same frequencies as those signals being leaked from the system.
It is the goal of this standard to address the coaxial cables and connectors in the system, and how to properly gauge their performance in this critical area.
After the configuration as in the picture, we perform a full sweep of the system and store the data for later use in calculating dynamic range.
