Introduction

Logic

Analyzers

Supported

The

E2418A Preprocessor Interface provides a complete interface

for monitoring external bus operations

a TMS32020/C25 target

system with the following logic analyzers:

1650A,

1650B,

1652B,

1660A/6W62A,

16510A,

16510B,

16511B,

16540/16541A,D,

16542A,

16550A.

Since the

E2418A only monitors external bus operations

the

TMS32020/C25, the TMS32020/C25 must be

operated

"microprocessor" mode (versus the "microcomputer" mode).

This manual is organized into three chapters

and

one

appendix:

• Chapter 1 explains how to install

and

configure the

E2418A

Preprocessor Interface for state analysis with the supportedlogic

analyzers.

• Chapter 2 provides reference information

the format

specification and symbols configuredby the

E2418A

software.

also provides information about the inverse

assembler and status encoding.

• Chapter3 contains additional reference information including

the characteristics and signal mappingfor

also contains information

servicing.

• AppendixA contains information

troubleshooting problems

difficulties which may occurwith the preprocessor interface.

Setting Up the HP E2418A

Introduction

Duplicating the

Master Disk

HP E2418A

This chapter explains how

install

and

configure

the

E2418A

Preprocessor Interface for state analysis

external bus operations

with the supportedlogic analyzers.

Before you use the

E2418A software, use the Duplicate Disk

operationin the disk menu

your logic analyzer

make a duplicate

copy

the

E2418A master disk. Store

the

master disk

and

use

the

back-up copy to configure your logic analyzer. This will help prevent

the

possibility

losing or destroying the originalfiles in

the

event

the

disk wears out, is damaged,

a file is accidentally deleted.
