Upstream Equalizer
 
The upstream equalizer data can indicate impedance mismatches or other cable impairments. High power levels in this chart, other than the main tap, indicate points of micro-reflection in the nearby cabling.
(Adaptive Equalization must be enabled on the CMTS for the active upstream channel in order for this page to display valid data.)
