When
eyeline
mode
is
active
,the
HP
83480-series
digital
communications
analyzer
controls
the
triggering
from
the pattern
generator
(
HP
71603B
,
71604B
,
70841B
,
71612A,
or
70843A).
One
data
point
is
taken
for
each valid
trigger
.
The
entire
data
pattern
is
transmitted
from
the
pattern
generator
before
the
next
trigger
.
Through
control
of
the
position
of
the
trigger
,
relative
to
the
data
pattern,
a
continuous
or
\eyeline"
trace
can
be
produced.
However
,
because
only
one
data
point
is
measured
for
each
repetition of
a
data pattern,
a
waveform
takes
longer
to
be
measured
than
a
normal
\dot"
eye diagram, triggering on a true clock signal.
