Abstract
A downstream bandwidth output level and/or output level tilt compensation device that can be inserted into a signal transmission line of a CATV system on a premise of a user. The device includes a tuner that identifies low and high band signal channels, and a channel analyzer that determines a format of each of those channels. A signal measurement measures low and high band signal strengths. An offset circuit adds or subtracts an offset value to the low and/or high band channel signal strengths depending on whether the respective channel is analog or digital. A microprocessor compares the low and high band signal strengths, including any offset values, to a predetermined signal strength loss curve. A variable output level compensation device and a variable slope adjusting circuit are provided to amplify and adjust the gain slope of the downstream bandwidth.
