This is one of the functions available for measuring D-to-C jitter. D-to-C jitter is
measured, excluding the phase difference of data signals having pulse widths of two
times the clock signal period (2T) or less. When the pulse width of the data signal is 2T
or less, the phase difference before and after that data signal is not measured.
The method for determining the jitter σ, jitter ratio σ/T, and average value is the same as
that for normal D-to-C jitter.
D-to-C jitter excluding 2T cannot be measured by products with suffix code -BDS.
