This ebook introduces real-time spectrum analysis (RTSA) and Full Band Capture technologies that enable broadband operators to remotely identify and resolve downstream RF impairments before customers experience service issues. It explains ten of the most common spectral impairments—including adjacency/alignment problems, missing channels, resonant peaking, roll-off, wideband noise, off-air ingress, foreign carriers, standing waves, tilt, notch, and suck-outs—while detailing the visual characteristics, root causes, and service impacts of each impairment. The guide connects faults such as faulty shielding, impedance mismatches, damaged connectors, poor headend combining, attenuation, equipment failures, and improperly configured plant components with downstream effects including degraded MER
