:SSEQuence:DEFine
[SOURce:]LIST[1]:SSEQuence:DEFine <length> reserves enough segment
sequence memory for a segment sequence of length segment names for the sequence
currently selected by
[SOURce:]LIST[1]:SSEQuence:SELect.

The segment sequence memory can store a maximum of 32,768 points (32,767 points if
a square, ramp, or triangle wave exists). All defined segment sequences share this
memory. Any one sequence can use any part of or all of this memory.
MINimum reserves 1 point; MAXimum reserves the largest available contiguous piece of
segment sequence memory.
Comments • Once a segment sequence has been DEFined, it must be deleted
(
[SOURce:]LIST[1]:SSEQuence:DELete[:SELected] command) before its reserved
length may be redefined. The contents and length of the list may be changed
repeatedly without re-executing the
DEFine command.
• By using the [SOURce:]LIST[1]:SSEQuence:DWELl:COUNt command, up to
4096 repetitions of a waveform segment can take only one point in the segment
sequence memory. This factor should be considered when reserving segment
sequence memory space.
• [SOURce:]LIST[1]:SSEQuence:DEFine initializes the segment sequence’s
waveform segment list to a zero current length and the repetition count and
marker enable lists to a length of 1 with a value of 1 (single repetition of each
segment, marker pulse generation enabled for all segments).
• Executable when Initiated: Yes
• Coupling Group: None

*RST Condition: Unaffected
• Power-on Condition: No segment sequences are defined.
Example Reserving Memory for a Segment Sequence
LIST:SSEQ:SEL ABC Selects sequence ABC.
LIST:SSEQ:DEF 1024 Reserves 1024 points for ABC.
