Chapter 4 Waveform Creation System
Memory Organization-Introduction
Memory Organization
Introduction
This section explains how the waveform memory is organized, the system of waveform numbering, how
default memory segments can be changed, and how standard functions can be inserted.
Default Partitioning
The total available waveform memory is 65,504 points. The memory is initially divided into partitions to
provide easy programming of 6 different waveforms. Five blocks of 2000 points each occupy the first
10K of memory. In addition, one of 20 standard waveforms can be readily recalled from the Function
menu and downloaded to 1000 points of memory from 10k to 11k. (A sinewave is the default Standard
Wave.)
Waveform Numbering
The first 5 blocks of memory are assigned Waveform Numbers. Additional Waveform Numbers can be
assigned (up to total of 100, depending on the number of points). Waveform Numbers are used to access
the memory blocks for initial waveform programming and to recall the waveforms later. Waveform
Numbers are arrayed in the memory in ascending order. Figure below shows the default waveform num-
bers and partitioning.

Changing Waveform Block Length
Standard Wave
The standard wave memory can be changed from its default value of 1000 points. (Minimum
waveform length is 16 points.)
