Such a Jitter File must be a 7-bit ASCII compatible text file; the Byte Order Mark
(BOM) that is common with UTF encodings is not allowed. The file must consist of
floating point values (in parsable format), separated by any whitespace and/or line end-
ings.
Each value describes the jitter for a symbol transition (even when the current and the
previous symbols are the same). The jitter value is implicitly given in the unit [s] and
denotes the delta between the time of the ideally expected transition (given by the data
rate) and the actual one. Positive values describe a transition that is occurring after the
ideally expected transition. The values are limited to the range -1.0e-3 to +1.0e-3. Any
values outside this range are limited to this range.
After the values in the file have been exhausted, the jitter values are taken starting
from the beginning of the file.
