Display
When you set the display to on, the softkey menu displayed depends on
which math operator you select. When magnify, versus, or FFT magnitude is
the operator, the Function Scaling softkey replaces the Vertical softkey.You
can then manually manipulate the scale and oset settings used to display the
new waveform.
The Display softkey turns on the display of the function, and it allows you
to adjust the size and position of the newly generated waveform (function)
for easily
viewing the
waveform
and
for
easily
making
measurements
.
Y
ou
can use
the knob
,
arrow
keys
,
or
keypad
to
size
and
position
the
function.
Software expansion
is
used
to
resize
the
function
when
you
change
the
display controls
.
It
does
not
change
the
way
the
hardware
acquires
the
data.
When display
is
set
to
on,
the
function
is
calculated
and
displayed.
Turning
the
display
to
o
ends
function
computation
and
erases the
function
from
the
display
.

1
is
displayed
in
the

that is
used
to
display
signals
from
slot
1,
and
function
2
is
displayed
in
the same

Scale
This function is only available when FFT magnitude is selected.
Scale changes the vertical size of the function, so that it is not clipped or too
small on the display.
