Df2/Df1 Ratio (Bluetooth)
is the ratio of Δf2avg to Δf1avg. The Core Specification requires the ratio to be at least 0.8, which verifies that the transmitter's Gaussian filter is not narrower than allowed (an overly narrow filter suppresses the deviation of alternating bit patterns).
A single burst carries either the Δf1 payload or the Δf2 payload, never both, so this is the one result in the table that is not computed from the selected burst: it is computed across all the bursts detected in the acquisition. Its cell reads until bursts of both payload families have been measured.
