DELAY
adjusts
the
electrical
delay
to
balance the
phase of
the DUT
.
This
is
performed
automatically
,
regardless
of
the
format and
the
measurement
being
made
.
Enough
line
length
is added
to or
subtracted
from
the
receiver
input
to
compensate
for
the
phase
slope
at
the active
marker position.
This
eectively
attens
the
phase
trace around
the active
marker
,
and
can
be
used
to
measure
electrical
length
or deviation
from
linear
phase
.
A
dditional
electrical
delay
adjustments are
required
on
DUT
s
without
constant
group
delay
over
the measured
frequency
span.
Since
this
feature
adds
phase
to a
variation
in
phase
versus
frequency
,
it
is
applicable
only
for
ratioed
inputs
.
