Sequence Table
As was explained in the above, the waveform memory can be
divided into smaller segments and up to 16 k segments can be
defined and used as individual arbitrary waveforms. Having a
limited size of waveform memory can, for some applications, pose a
limitation however, if sections of the waveform are repetitive, one
may use the sequence generator to take these segments and
replay them as part of the complete waveform without losing
valuable memory space and without scarifying waveform coherence
and integrity. The tool for combining repetitive and multiple
segments in one long waveform is called Sequence Generator and
ArbConnection has a special dialog box where sequences are
designed. This tool is called – Sequence Table.
Using the Sequence table you can use waveforms that you already
downloaded to the 3152B from the Segment table, link and loop in
random order to create one long and complex waveform that
combines the individual memory segments.
Figure 4-11, Sequence Table Example
The Sequence Table is highlighted in Figure 4-11. To access the
Sequence table, click anywhere on the Sequence Table area. If it
was not yet, it will turn white as opposed to the Segment Table area
that turns gray.
There are five major elements that you should consider while
programming a sequence table. They are: Link, Seg, Loops, Adv
and Sync. These terms are explained below.
