This object reports the minimum Eb/No observed during the sample period, in 0.1 dB units, returning 999 if the demodulator was unlocked at any point during that period. This captures the worst moment within each sample window rather than a smoothed average, making it the more sensitive indicator for catching brief fade events, like a passing cloud or a momentary obstruction, that an averaged value might dilute into an unremarkable-looking mean. A sample interval showing an average Eb/No of 8.5 dB but a minimum of only 3.0 dB reveals a brief but significant fade occurred within that window even though the overall average still looks acceptable.
