Despite the source description being a copy of the Min object's text, this object's name indicates it reports the average Eb/No across the sample period, in tenths of a dB, with 999 meaning the demod lost lock during the interval. Comparing this average against cdm570StatisticMinEbNo from the same row is how an admin distinguishes a link with a brief dip from one that is consistently running with marginal margin. An average of 90 (9.0 dB) alongside a minimum of 65 (6.5 dB) in the same sample would indicate a short fade event rather than sustained degradation.
