Description: This attribute represents the RMS value of the group delay ripple expressed in units of 0.001 nsec. This attribute represents the group delay variation across the entire OFDM channel. The slope component calculated for the GroupDelaySlope is subtracted from the frequency domain data and the RMS ripple is calculated from the resultant data. This attribute is not stored in the data file.
What is docsPnmCmOfdmChEstCoefGrpDelayRippleRms?
The RMS group delay ripple, in thousandths of a nanosecond, across the whole downstream OFDM channel, after removing the linear group-delay slope; this value is not stored in the data file itself. A smoother statistical summary of group-delay variation than the peak-to-peak figure, used the same way to flag reflection/filter issues.
