<edge_num

::
=
an integer,
-127 to
127
(excluding 0) specifying a displayed
edge

Example:
OUTPUT
707;":MEAS:DEFINE
DELAY,POS1TIVE,1,UPPER,NEGATIVE,2,MIDDLE"
This example will
set
the
parameters
for
a
time
measurement
from
the
first
positive
edge
at
the
upper
threshold
level
to
the
second
negative
edge
at
the
middle
threshold.
If
one
source
is
specifed,
both
parameters
apply
to
that
signal.
If
two
sources
are
specified
the
measurement
is
from
the
first
positive
edge
on
source
1
to
the
second
negative edge
on source
2.
