When you enable the internal editor, the screen
splits into
a smaller top window and a larger
bottom window.
The smaller, top part of the screen becomes
an overvie
w, which shows the entire waveform
memory. A box shows the zoomed-in portion of
the waveform.
The large
r, lower part becomes the zoomed-in
view of the overview, as defined by the box in the
top part of the screen. This lower part shows up
to 500 poi
nts of the record.
Turn the Multipurpose a knob to select a point
to edit.
Turn the
Multipurpose b knob to set the voltage
level of that point. The voltage level is a function
of the current amplitude and offset settings for
the wav
eform.
Use the side menu items to add or remove points
from the waveform.
6. Push Create New from the lower-menu to
make a fresh arbitrary waveform.
On the
resulting side menu, turn
Multipurpose a or use the keypad to defi ne
the number of points in the waveform. Your
wave
form can have up to 131,072 points.
Turn Multipurpose b to choose the basic
function. Choose between square, sine,
ramp
, pulse, and noise.
Push OK Create to build the new waveform.
