Techniques for Accurate Measurement of Cable TV Network Downstream RF Signal Levels

Proper cable network operation relies upon RF signal levels being within specification. RF signals are just about everywhere in modern cable systems: antenna sites, headends, hub sites, nodes, coax distribution networks, and subscriber drops. While ensuring that signal levels are what they’re supposed to be won’t fix or avoid every problem, correct signal levels are an important part of optimizing overall RF performance.
