What Are
Sequenced
Waveforms?
Sequenced waveforms are constructed from two or more arbitrary
waveforms, which are linked and looped in any way you can
imagine, as long as you observe the limitations set forth in the
specification section of this manual.
The first thing to do before you can generate sequenced waveforms
is download waveforms to the 2074. You may use ArbConnection
or any other application to create waveform segments. Then, you
can build your sequence table. An example of how sequenced
waveforms work with three different waveforms is demonstrated in
Chapter 1, Figures 1-12 through 1-15.
The sequence table, as shown in Figure 3-17, specifies: Link, Seg,
Loops and Adv. Description of the various elements within the
sequence table is given below.
Link
- This parameter defines an index array for the sequence
generator. When generating sequences, the instrument steps
though the link # in descending order therefore, make sure that you
enter your waveform segments in exactly the order you would like
them at the output.
Seg
- This parameter associates waveform segments with links.
You can use different segments for different links or you can use
the same segment for a number of links. There are no limitations
how you associate links to segments, except you can not program
in the sequence table segments that were not defined earlier.
Loops
– This parameter define how many times the segment will
loop for the selected link. For example, if you program 2, the
