Limit

Concept
Saving
the
Limit
Line
T
able
Limit
line information
is lost
if the
LINE
switch
is
turned
o.
However
,
the
4
Save
5
and 4
Recall
5
keys
can save
limit line
information along
with
all
other
current
analyzer
settings
.
Limit
line
table
information can
be saved
on a
disk.
Osetting
the
Sweep
P
arameter
or
Amplitude of
the Limit
Lines
All
limit
line entries
can be
oset in
either sweep
parameter
or
amplitude
values
.
The
oset
aects
all
segments simultaneously
.
Supported
Display
F
ormats
Limit
lines
are
displayed
only
in
Cartesian
format.
In
polar
and
Smith
chart
formats
,
limit
testing
of
one
value
is
available
.
The
value
tested
depends
on
the
marker
mode
and
is the
magnitude
or
the
rst
value
in
a
complex
pair
.
The
message
\
NO
LIMIT
LINES
DISPLAYED "
is
shown
on
the
display
in
polar
and
Smith
formats
.
Use
a
Sucient
Number
of
P
oints
or
Errors
May
Occur
Limits
are
checked
only
at
the
actual
measured
data
points
.
If
you
do
not
select
a sucient
number
of
points
,
it
is
possible
for
a
device
to
be
out
of
specication
without
a limit
test failure
indication.
T
o
avoid
this
,
be
sure
to
specify
a
high
enough
number
of
points
.
In
addition,
if specic
sweep
parameter
points
must
be
checked,
use
the
list
sweep
features
described
in
\Reducing Sweep
Time
(Using
List
Sweep)"
in
Chapter
9
so
that
the
actual
measured
data points
are
checked.
Displaying,

Limit T
est
Data
The
\list
values"
feature
in
the
copy
menu
prints
or
displays
a
table
of
each
measured
sweep
parameter
value
.
The
table
includes
limit
line
and
limit
test
information
(if
these
functions
are
turned
on).
If
limit
testing
is
on
,
an
asterisk
\
3
"
is
listed
next
to
any
measured
value
that
is out
of limits
.
If
the
limit
lines
are
on
,
and
other
listed
data
allows
sucient
space,
the following
information
is
also
displayed:
Upper
limit
and
lower

The
margin
by
which
the
device
passes
or
fails
the
nearest
limit
Results of Plotting or Printing the Display with Limit Lines ON
If limit lines are on, they are shown when you print or plot the display
. If limit testing is
on ,
the P
ASS or F
AIL message is included as well.
