What Are Sequenced
Waveforms?
Sequenced waveforms are made of a number of arbitrary
waveforms which can be linked and repeated in various manners.
Sequenced waveforms are generated from waveforms stored in a
library of memory segments. Before using a sequence of
waveforms, load arbitrary memory with the required waveforms.
Use TRAC# or shared memory methods to load waveforms into
memory.
Information on how to partition the memory and load waveforms is
given in the section entitled Generating Arbitrary Waveforms.
An example of how sequenced waveforms work is demonstrated in
the following figures. Figure 3-3 shows a sine(x)/x waveform that
was loaded into segment 1. Figure 3-4 shows a sine waveform that
was loaded into segment 2. Figure 3-5 shows a pulse waveform
that was loaded into segment 3.
The sequence generator lets you link segments in user-defined
order and repeat each segment as many times as needed.
