Arbitrary Memory
Management
The Model 3162B's arbitrary memory consists of a fixed length of 1,048,576
points. 2112 points are always reserved for the built-in standard waveforms. The
maximum size arbitrary waveform that can be loaded into memory is 1,046,464
points long.
It is not necessary to use the entire length of this memory. The memory can
be partitioned into smaller segments, and different waveforms can be loaded
into each segment. The memory can be partitioned into 4096 segments, each
having a unique length and sample rate. Minimum segment length is 16 points.
Information on how to partition the memory is given in the following paragraphs.

Management
Commands
Arbitrary memory can be divided into smaller segments. Up to 4096 different
arbitrary waveforms can be stored in the Model 3162B’s memory. The length
of each segment and its associated sample clock rate are left to the user’s
discretion. To partition the arbitrary waveform memory, use the following
command:
TRACe:DEFine <segment_number>,<length>,<divider>
Note that numbers, not names, are assigned to segments that are defined.
Segment numbers can range from 1 through 4096. The order of assignment is
not important as long as the sizes of the segments, having already been
defined, are not changed.
The length of any segment may be programmed from a minimum of 16 points
to the maximum memory size, which is 1,046,464 words long.
Note
Minimum segment length is 16 points. Segment size may
be set from 16 points to the maximum memory size in
increments of 8 points. A size of 1002 is not a valid
