Description: This attribute represents the slope in 0.001 dB per MHz in the magnitude of the equalizer coefficients. The slope is calculated as the slope of a linear least squares fit of the frequency domain data. This attribute represents the slope across the entire OFDM channel.
Note: An algorithm for calculating the ripple and slope for these measurements is provided in section D.3 of the the DOCSIS 3.1 CM OSSI Specification.
What is docsPnmCmOfdmChEstCoefAmpSlope?
The linear amplitude slope, in thousandths of a dB per MHz, fitted across the downstream equalizer coefficient magnitudes for the whole OFDM channel. A large slope indicates tilt in the plant's frequency response that the equalizer is having to compensate for.
