.
Move
the cursor
down
into
the
Edge
field
anduse
the
NEXT[]
key
to
enter
a
positive-going
transition
requirement
(up
arrow)
for
channel
B2
(third
from
right-hand
side) of
the timing
pod
.
14
.
Press
the
RUN
key
.
The
state
measurement
in
the
analyzer
will
becompleted
asbefore
.
After
the
state
trigger
has
been
found,thetiming
function
will
search
for
thetiming
trigger
.
If
itfindsthetiming
trigger,
it
will
complete
its
trace
and
show
awaveform
display
.
If it
does
not
find
its
trigger,
the
analyzer
will
show
the
message
"Waiting
for
Timing
Trigger"
on screen
.
In
this
case,
press
the
STOP
key
.
The
message
on
screen
will
show
"Trace
Aborted"
.
There
will
be
waveforms
displayed
.

.
Press
the
LIST
keytwo
times
.
The
trace
list
that
was
completedby
the
state
measurement
function
will
be
displayed
.
It
will
show
the
state
trigger
on
screen,
along
with
other
states
it
captured
.
16
.
Press
the
TRACE
key
two
times
.
This
will
place
the
trace
specification
for
thetiming
function
on
screen
.

.
Move
the cursor
down
into
the
Pattern
field
and
press
and
hold
the
DON'T
CARE
key

.
This
can
also
be
done
by
pressing

.
Now
thetiming
analyzer
trigger
will
be
satisfied
when
the
first

edge
is
found
on
channel
2
in
pod

.
18
.
Press
the
RUN
key
.
The
analyzer
will
search
through
the
incoming
states
until
it
finds
the
state
trigger
.
When
it
finds
the
state
trigger,
it
will
begin
capturing
states
into
memory,
and
at
the
same
time,
it
will
arm
thetiming
analyzer
to
search
for
its
trigger
.
The
timing
analyzerwill
monitorthe
incoming
activity
until
it
finds
a
rising
edgeon
bit
B2
.
Then
it
will
store
a series
of
samples
of
activity
to
complete
its
timing
measurement
.
It
will
show
"Trace
Complete"on
thetop
of
the
screen,
and
waveforms
of
timing
information
across
the
display
.

"Master"
field
and
press
the

change
[State] to
[Timing]
.
This
makes
the

recognize
its
timing trigger
before
it
can
arm
the
state
function
to
recognize
the
state
trigger
.
21
.
Press
the
RUN
key
.
The
analyzer
will
begin
its
measurement
by
looking
for
the
condition
that
satisfies
its
timing trigger
.
When
it
finds
this
condition
(rising
edge
on
B2),
it
starts
collecting
timing
information,
and
arms
the
state
measurement
function
to
look
for
its
trigger
.
The
timing
analyzer
displays
its
waveform
information
on
screen
while
the
state
function
completes
its
measurement
.
22
.
Press
the
LIST
key
