Description: This attribute represents the slope in 0.001 nsec per MHz in the group delay of the equalizer coefficients. 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 DOCSIS 3.1 CM OSSI Specification.
What is docsPnmCmOfdmChEstCoefGrpDelaySlope?
The linear group-delay slope, in thousandths of a nanosecond per MHz, fitted across the downstream equalizer coefficients for the whole OFDM channel. A significant slope here indicates systematic delay distortion (e.g. from filter roll-off) across the channel bandwidth.
