plete length of this memory. The Model 8024 permits
partition of the arbitrary memory to smaller memory
segments. It is possible to divide the memory from 1
to 99 memory segments and assign different size to
each segment. Minimum segment size is 10 points.
3-15-3. Partitioning The Memory
As discussed above, the arbitrary memory may be divided
into smaller segments. So, up to 99 different
arbitrary waveforms can be generated with the Model
8024. The length of each segment is left totally to the
user’s discretion. The arbitrary waveforms are active
when the ARB light is on. To partition the arbitrary
memory press the [WAVEFORM] button and observe
that the display reads as follows:
Output Segment
01 (Empty)
Segment remains empty until you assign it a size.
Press the cursor button to move one menu down and
observe that the display reads as follows:
Move the cursor under the fourth digit and rotate
the dial clockwise to increment the reading to 01000.
Before you proceed, compare the display reading and
make sure that it looks exactly as follows:
SEG01=01000Pts
64536 Pts left
To complete the segment size modification process
press the [ENTER] button. The instrument will prompt
you with the following message:
Change SEG Size?
ENTER=yes
If you press [ENTER], the size which you have selected
will lock-in permanently and the above reading will
change as follows (the same question will be asked if
you’ll try to leave this menu without finalizing the
process):
SEG01=01000Pts
63536 Pts left
You may continue partitioning the memory using the
same procedure to assign sizes to other segments. You
may do so by incrementing SEG01.
3-15-4. Loading Arb. Waveforms
Model 8024, when supplied first, does not have any
arbitrary waveforms loaded into its memory. The loading
process can be done either from the front panel
or from a GPIB station. Front panel loading of arbitrary
waveforms will be discussed now, while GPIB operation
is discussed in Section 4 of this manual.
Assuming that you have already assigned size to
at least one segment, you may proceed to load the
segment with one of the standard functions that are
available from the front panel. From the menu shown
before, press the cursor button to go down one menu
layer. The display reading will change as follows:
LOAD Sine
into SEG01 /ENT
The cursor is placed under the Sine function indicating
that this is the only parameter that may be
changed. Rotate the dial to select another function, then
press [ENTER] to load the selected function into the
arbitrary memory.
3-15-5. Modifying Arb. Functions
The Model 8024 does not provide front panel editing
capabilities, besides a few built-in modifiers. If you
select to load, for instance, the Sine function, it will
be loaded exactly as it was set up in the standard waveforms
menu. Therefore, if you want to load this function
with one of its ancillary function changed, do so first
in the standard waveforms menu, then load it into the
arbitrary memory.
There are a number of modifiers built-in the ARB menu.
They are: Clear, Fill, Offset, Invert, and AM. These
modifiers operate globally on the entire segment. To
access the modify menu, press the cursor control button
to go one menu layer down. The display will change
to read as follows:
SEG01 MODIFY
Clear
Operating Instructions
The cursor is positioned under the Copy function indicating
that this function can be changed. Use the
dial to select one of the modifier function, then move
