with

keystroke
.
Sweep values
are not
aected, only
scale and
reference
values
.
The
analyzer
determines
the
smallest
possible
scale factor
that will
put all
displayed data
onto
the
vertical
graticule.

SCALE/DIV Changes
the
response
value
scale
per
division
of the
displayed trace
.In
Smith, polar
,
and
admittance
chart
formats
,
this refers
to the
full scale
value at
the
outer
circumference
and
is
identical to
the reference
value.

REFERENCE
POSITION
Sets
the
position
of the
reference line
on the
graticule of
a
Cartesian
display
(with
0
at
the
bottom line
of the
graticule and
10 at
the
top
line).
It
has
no
eect
on
a
Smith,
polar
or admittancechart
format. The
reference position
is
indicated
with
a
small
triangle
just
outside
the graticule
,on
the left.

REFERENCE
V
ALUE
Changes
the
value
of
the
reference
line
, moving
the measurement
trace
correspondingly
.
In
Smith,
polar
and admittance
chart formats
, the
reference
value
is
the
same
as
the
scale
and
is
the value
of the
outer circle
.

REFERENCE
Makes
the
reference
value
equal
to the
marker's absolute
value(regardless
of
the
delta
marker
value).
The
marker
is
eectively
moved
to
the reference
line
position.
In
Smith,
polar
and
admittance
chart
formats
this
function
makes
the
full
scale value
at
the
outer
circle
equal
to
the
marker
response
value
.
