This letsyo u immediately see each statistic in its proper context. For example ,
anerror rate of 50% is insignificant if Observer has only analyzed two
packets,but quite significant if thousands of packets have been analyzed.
Thebar g raphs to the right of the dial show current bandwidth ut ilization (U),
theaverage strength (S), and the average quality (Q) of the signal. These
metersalso indicate (with watermark“floats”) the minimum and maximum
values that Observer has seen since the last polling peri od.
