These examples guides
you
through the creation
of
three Arbitrary waveforms. One
waveform, "gray," demonstrates how to create and output an Arb waveform.
The
other
two
Arb
waveforms,
"synel"
and
"syne2" will demonstrate waveform sequencing
(paragraph 3.8).
Example 2 Creating an Arbitrary Waveform Using Line Draw
This
example
creates
waveform
that simulates a nine-step gray scale
video
signal.
Paragraph 5.5.2, example 2 eontains the remote SCPI programming equivalent
of
this
example. You will use this waveform with example 3.
If
you want to view
the
signal on an oscilloscope, connect the
Madel
395
ta
the seope
as describedin paragraph 3.5. First setup the Model395 as described in example
l,
steps
1,2,
and 3.
Step 1 Naming and Sizing the Waveform
The fust step in creating the waveform is ta name it and define its size. Start by pressing
the
CREAlE
key under
WA
VEFORM EDIT which displays the Create New Waveform
screen.

there are additional screens.
If
you pressed F4, "create from copy

an existing waveform and modify the copy.
Give the waveform a name using the knob and right cursor key. Rotate
the
knob until
thefust character displays "g" and press the right cursor. Again rotate the knob
Ulltil
the
second character displays "r" and press the right cursor. Continue until you have entered
"a" and "y." Both letters and numbers can
be
used in names, but the [rrstcharacter must
always
