3152B User Manual
Publication No. 980935 Rev. A
You may use the above command to create as many segments as
required. However, if you have many segments, it is more efficient
to combine all segments into a single waveform, and then create a
memory partition table for the individual waveform segments. To do
this, use the following command:
segm <array>
Downloads the entire memory partition
table to the instrument in one
operation.
Chapter 5 provides details on the use of this command.
Deleting Memory Segments
To delete a waveform memory segment, use the following
command:
trac:del <value>
Deletes a segment (specified by
<value>) from the available segment
list but does not erase the contents of
the segment.
Note that if you delete a segment, the memory portion that
belonged to this segment is no longer accessible. The next
segment defined is placed at the end of the partition table. If you
delete the last segment that you defined, then the next downloaded
data will overwrite the memory of the deleted segment. If you delete
segments often, large portions of the memory will become
inaccessible. Therefore, it is suggested that you periodically clear
the entire memory and reload the waveforms that you intend to use.
To delete the entire memory partition table use the following
command:
trac:del:all
Removes the entire partition table,
allowing definition of a new segment
table.
Tip
The trac:del:all command deletes the partition table but
leaves the data in the arbitrary memory intact. Therefore,
if you made a mistake and want to restore the segments,
just re-load the partition table. The waveform memory is
overwritten. Every time you download new waveform
data, the waveform memory data for that segment is
overwritten.
Loading Arbitrary
The easiest way to download waveforms to the 3152B is with
ArbConnection. Using this application, you may define, create, and
