3-122 AWG610 Arbitrary Waveform Generator User Manual
The sequence to be called from a sequence is called Subsequence, and the nested
level is limited to 1. The number of sequence steps expanded in the sequence
memory may go over the sequence memory capacity, depending on how you
configure sequence and/or subsequence.
The enhanced settings which include, Infinity, Trigger Wait, Goto One, and
Logic Jump are neglected in the subsequence when you set the run mode to
Enhanced.
Sequence memory usage. Sequence memory controls the maximum number of
subsequence calls and their repeat counts that can be run. When you load a
sequence, the AWG610 Arbitrary Waveform Generator compiles the sequence
and subsequence lines into internal codes that are stored in the sequence
memory. The AWG610 Arbitrary Waveform Generator then uses the sequence
memory code to output the waveform data. There is one internal code item for
each sequence line except for lines that contain a subsequence call.
For subsequence calls without a repeat count, the AWG610 Arbitrary Waveform
Generator compiles a number of internal code items equal to the number of lines
in the subsequence.
For subsequence calls with a repeat count, the AWG610 Arbitrary Waveform
Generator compiles a number of internal code items. These are equal to the
repeat count for that subsequence call times the number of lines in the subse-
quence. For example, if a sequence line has a subsequence call with the repeat
count of 25 and that subsequence has two lines, the AWG610 Arbitrary
Waveform Generator generates 50 internal code items for that sequence line and
stores them in the sequence memory. This occurs for each subsequence call.
Figure 3–29 illustrates how the AWG610 Arbitrary Waveform Generator
compiles the sequence and subsequences into the internal codes and stores them
in the sequence memory.
