The
standard
delay
measurement occurs
when
in
the
standard
mode
(not
user-defined)
and
is
not
a
jitter
measurement.
standard
delay
=
mid-threshold of
the
first
edge
of
second
parameter
minus
mid-threshold
of
the
first
edge
of
the
first
parameter
Note
Negative
delay
is
possible
User
defined
delay
=
second channel
edge
minus
first
channel
edge
+
width The
+
width
algorithm
has
standard and
user-defined considerations.
if
first
edge
is
rising
then
+
width
=
mid-threshold
crossing
of
first
falling
edge
•
mid-threshold
crossing of
first
rising
edge
else
+
width
=
mid-threshold
crossing
of second
falling
edge-
mid-threshold crossing
of first
rising
edge
User-defined
is
the
same
as
Standard
definition
except
user-defined
threshold.
