.
If
the
through-path
optical
insertion

output
amplitude
test
have
just
been
performed,
initializing
the
test
equipment
is
not
necessary
.
Otherwise
,
set
the
test
equipment
to
the

Procedure
P
erform
this
procedure
rst
with
a
1310
nm
source
and
then
with
a
1550
nm
laser
source
.
1.
Make
sure
the
analyzer
delay
is
set
to
<50
nsec
for
all
jitter
measurements
,
and
the
electrical
channel
is
switched
on.
2.
Set
the
analyzer
electrical
channel
oset
to
0.0
VDC.
3.
Set
the
optical
power
into
the
HP
83447A
to
015
dBm.
4.
A
djust

position
(do
not
exceed
100
nsec)
until
one
of
the

transition
crossings
is
in
the
center
of
the
display
.
5.
Select
jitter
measurement
from
the
Measure
Eye
menu.
6.
Increase
the
vertical
sensitivity
to
20
mV/div
and
the
time/div
to
20
psec/div
.
7.
Switch
to
the
time
histogram
mode
.
8.
A
djust
the
horizontal
cursors
to
sample
the
narrowest
portion
of
the
transition
crossings
(the
\waist").
K
eep
the
cursors
within
2.5
mV
of
each
other
