This graph describes the low frequency stability of the VFC110:
the ratio of the 1
σ
point of the distribution of 100 runs (where
each mean frequency came from 1000 readings for each gate
time) to the overall mean frequency.
Jitter is the ratio of the 1
σ
value of the distribution of the period
(1/f
OUT
, max) to the mean of the period.
