Using Combined Waveform Segments and Segment Sequences
Using Combined Segment Lists and Combined Segment Sequence Lists to
generate arbitrary waveforms is one of the fastest methods to download or
transfer waveform segments and segment sequences to the AFG. Both can
be downloaded to the AFG either as Definite Length or Indefinite Length
Arbitrary Block Data.
The Combined Segment Lists transfers both the arbitrary waveform
segment data and marker pulses to the AFG. The lists are sent as 16-bit
Integers in either the Signed or Unsigned number format. (See “Using
Combined Signed Data” on page 239 for more information.)
The Combined Segment Sequence List selects the waveform segments,
enables the marker output, and sets the repetition count for each waveform
segment to be output. Each data code in a Combined Segment Sequence
List is sent as a 32-bit Integer in the Unsigned number format.

Figure 7-2 shows a single 32-bit integer used for a Combined Segment
Sequence List. Bits 0 through 16 select the combined or regular waveform
segments for output, bit 18 enables the marker output, and bits 20 through
31 sets the repetition count.
A Combined Segment Sequence List determines the order and how often a
waveform segment is to be executed. Thus, each waveform segment,
marker enable, and repetition count has a unique data code.
32-Bit Combined List that defines the segment lists to be executed, enables
the marker, and defines the repetition count for the segment lists.
