Printing History
New editions are complet,e revisions of the manual. Update packages,
which are issued between editions, contain additional and replacement
pages to be merged into the manual by the customer. The dates on the
title page change only when a new edition is published.
A software code may be printed before the date; this indicates the version
of the software product at the time the manual or update was issued.
Many product updates and fixes do not require manual changes and,
conversely, manual corrections may be done without accompanying
product changes. Therefore, do not expect a one to one correspondence
between product updates and manual updates.

Introduction
Logic
Analyzers
Supported
The HP E2418A Preprocessor Interface provides a complete interface
for monitoring external bus operations of a TMS32020/C25 target
system with the following logic analyzers: HP 1650A, HP 1650B,
HP 1652B, HP 1660A/6W62A, HP 16510A, HP 16510B, HP 16511B,
HP 16540/16541A,D, HP 16542A, or HP 16550A.
Since the HP E2418A only monitors external bus operations of the
TMS32020/C25, the TMS32020/C25 must be operated in the
"microprocessor" mode (versus the "microcomputer" mode). In
microprocessor mode, the bus operations to the external program
memory are available to be capturedby the logic analyzer. Accesses to
TMS32020/C25 internal resources are not presented on the external
data bus.
The TMS32020/C25 configuration software on the flexible disk sets up
the format specification menu of the logic analyzer for compatibility
with the TMS32020/C25 microprocessor. It also loads the inverse
assembler for obtaining displays of TMS32020/C25 data in
TMS32020/C25 assembly language mnemonics.
The following logic analyzers are supportedby the HP E2418A
Preprocessor Interface:
HP 1650A, HP 16508, HP 16528, HP 16510A, and HP 165108
These logic analyzers provide 1 k of memory depth with either 80
channels of 35 MHz state analysis (25 MHz state analysis for the
HP 1650A or HP 16510A) or 80 channels of 100 MHz timing
analysis.
HP 1660A/61A/62A
The HP 1660A/6W62A Logic Analyzers provide 4 k of memory
depth with 136 channels (HP 1660A), 102 channels (HP 1661A),
or 68 channels (HP 1662A) of 100 MHz state analysis or 250 MHz
timing analysis. These logic analyzers also support various
combinations of mixed state/timing analysis.

lntroduction-2
HP 165118
This logic analyzer combination provides 1 k of memory depth with
either 160 channels of 35 MHz state analysis, or 80 channels of
35 MHz state analysis and80 channels of 100 MHz timing analysis.
HP 16540A,D with one HP 16541A,D Expansion Card
This logic analyzer combination provides 4 k of memory depth
(16 k with the D version) with up to 64 channels of 100 MHz state or
timing analysis.
HP 16542A (Master Card and two expansion cards)
This logic analyzer combination provides 1 M of memory depth
with 48 channels of 100 MHz state or timing analysis.
HP 16550A
This logic analyzer provides 4 k of memory depth with 102 channels
per card of 100 MHz state analysis or 250 MHz timing analysis. The
logic analyzer will also support various combinations of mixed
state/timing analysis.
This manual is organized into three chapters and one appendix:
• Chapter 1 explains how to install and configure the HP E2418A
Preprocessor Interface for state analysis with the supportedlogic
analyzers.
• Chapter 2 provides reference information on the format
specification and symbols configuredby the HP E2418A
software. It also provides information about the inverse
assembler and status encoding.
• Chapter3 contains additional reference information including
the characteristics and signal mappingfor the HP E2418A
Preprocessor Interface. It also contains information on servicing.
• AppendixA contains information on troubleshooting problems
or difficulties which may occurwith the preprocessor interface.

Introduction
Duplicating the
Master Disk
HP E2418A
This chapter explains how to install and configure the HP E2418A
Preprocessor Interface for state analysis of external bus operations
with the supportedlogic analyzers.
Before you use the HP E2418A software, use the Duplicate Disk
operationin the disk menu of your logic analyzer to make a duplicate
copy of the HP E2418A master disk. Store the master disk and use the
back-up copy to configure your logic analyzer. This will help prevent
the possibility of losing or destroying the originalfiles in the event the
disk wears out, is damaged, or a file is accidentally deleted.
