DG2040 Data Generator

Data Structure Overview

To make full and efficient use of the DG2040 Data Generator, you need to
understand the data structures of the DG2040 Data Generator. This section
presents an overview of the pattern data, setup data, and sequence data. Figure
2-6 shows the data structures that are described in the following sections. Table
2-2 lists the data structure related technical terms that appear frequently in the
operating procedure descriptions.

Pattern data

Basic data for patterns, consisting of 2Ćbit words

Memory size

The number of pattern data words (360 words to 256 K words)

Group allocation

Definitions of pattern data bit combinations

Block delimiter

Delimiter that defines pattern data start and stop points

Block division

Pattern data division by block delimiters

Output channel allocation

Definition of the corresponding relationship between pattern data

and output bits

Setup data

Settings for the above items

Sequence data

Pattern output sequence program

Pattern data is the basic data that defines the digital signals to be output. The
pattern data is a collection of 2-bit words. The total number of words is called
the memory size. The memory size can be any value from a minimum of
360 words to a maximum of 256 K words (262,144).
