TLA7PG2 Pattern Generator Module Instructions
The pattern generator module adds pattern generator capability to the logic
analyzer. You can generate specific data patterns to a target system and then use
the logic analyzer to evaluate the resultant data from the target system.
The pattern generator module functionality can be divided into blocks as shown
in Figure 1. Refer to the figure as you read about the functional blocks.

The probe interface serves two purposes: to detect event and inhibit information
and to output data to a target system. In addition to sending pattern generator
data to the target system, the probe also sends clock and strobe information.
You can connect up to four probes to a single module. Each probe supports either
8 or 16 channels.
For information about connecting the Pattern Generator probes to both the
TLA7PG2 module and the target system, refer to the TLA700 Series Logic
Analyzer Installation Manual.
The pattern generator program is the heart of the pattern generator module. You
can create blocks of data vectors to work together to create complex pattern
generator programs. The program uses external and internal events to determine
specific actions such as loops and branches to other data blocks. The program
can be controlled by an internally selected clock or by an external clock through
a front-panel BNC connector.
