Technical data

In the "Bit Comparison without PCIe3 SKPOS" error ratio mode, this query returns
the "instantaneous" SKPOS Bit Ratio, calculated from the counts obtained in the
last deci-second. This value is available even when the accumulation is turned off.

This query is a contraction of the phrase Data Rate Ratio.
In the "8B/10B Symbol Comparison" error ratio mode, it returns the ratio of the
number of filler symbol count to the expected filler symbol count received in the
current (or last completed) accumulation period, specified by the gate period.
In the "Bit Comparison without PCIe3 SKPOS" error ratio mode, it returns the ratio
of the number of SKPOS bit count to the Expected SKPOS bit count received in the
current (or last completed) accumulation period, specified by the gate period.
