Preface: Microprocessor Support Documentation
This instruction manual contains specific information about the TMS 801 APIC
bus support and is part of a set of information on how to operate this product on
compatible Tektronix logic analyzers.
If you are familiar with operating bus supports on the logic analyzer for which
the TMS 801 APIC support was purchased, you will probably only need this
instruction manual to set up and run the support.
If you are not familiar with operating bus supports, you will need to supplement
this instruction manual with information on basic operations to set up and run the
support.
Information on basic operations of bus supports is included with each product.
Each logic analyzer has basic information that describes how to perform tasks
common to supports on that platform. This information can be in the form of
online help, an installation manual, or a user manual.
This manual provides detailed information on the following topics:
H Connecting the logic analyzer to the system under test
Manual Conventions
H Setting up the logic analyzer to acquire data from the system under test
H Acquiring and viewing disassembled data
H The TMS 801 APIC probe adapter
This manual uses the following conventions:
H The term disassembler refers to the software that disassembles bus cycles
into instruction mnemonics and cycle types.
H The phrase “information on basic operations” refers to online help, an
installation manual, or a basic operations of bus supports user manual.
H In the information on basic operations, the term XXX or P54C used in field
selections and file names can be replaced with APIC. This is the name of the
bus in field selections and file names you must use to operate the APIC
support.
H The term system under test (SUT) refers to the bus-based system from which
data will be acquired.

TMS 801 APIC Bus Support Instruction Manual
Getting Started
Support Description
This chapter provides information on the following topics:
H The TMS 801 APIC bus support
H Logic analyzer software compatibility
H Your APIC system requirements
H APIC support restrictions
H How to connect to the system under test (SUT)
H How to apply power to and remove power from the probe adapter
The TMS 801 bus support disassembles data from systems that are based on the
Intel APIC bus. The support runs on a compatible Tektronix logic analyzer
equipped with a 102/136-channel module, or a 96-channel module.
Refer to information on basic operations to determine how many modules and
probes your logic analyzer needs to meet the minimum channel requirements for
the TMS 801 bus support.
You can also use this product with another Tektronix probe adapter designed for
a microprocessor that follows the APIC bus protocol. Examples are the TMS 109
Pentium\100, or the TMS 110 Pentium Pro microprocessor supports.
A complete list of standard and optional accessories is provided at the end of the
parts list in the Replaceable Mechanical Parts chapter.
To use this support efficiently, you need to have the items listed in the information on basic operations as well as the APIC External Architecture Specifications,
Intel,Version 4.0 Intel.
Information on basic operations also contains a general description of supports.
Logic Analyzer Software Compatibility
The label on the bus support floppy disk states which version of logic analyzer
software the support is compatible with.
TMS 801 APIC Bus Support Instruction Manual
1–1
Getting Started
Logic Analyzer Configuration
To use the APIC support, the Tektronix logic analyzer must be equipped with at
least a 102/136-channel module or a 96-channel module. The module must be
equipped with enough probes to acquire channel and clock data from signals in
your APIC-based system.
Refer to information on basic operations to determine how many modules and
probes the logic analyzer needs to meet the channel requirements.
Requirements and Restrictions
You should review the general requirements and restrictions of bus supports in
the information on basic operations as they pertain to your SUT.
You should also review electrical, environmental, and mechanical specifications
in the Specifications chapter in this manual as they pertain to your system under
test, as well as the following descriptions of other APIC support requirements
and restrictions.
System Clock Rate. The bus support can acquire data from the APIC bus at
speeds of up to 33 MHz
APIC Bus Interface Cables
The TMS 801 APIC Bus support product comes with three cables for different
methods of connecting to the system under test. The connection procedures in
this chapter inform you when to use which cable. Refer to Table 1–1 to determine
which cable to use for your application.

Connecting to a System Under Test
Before you connect to the SUT, you must connect the probes to the module. Your
SUT must also have a minimum amount of clear space surrounding the bus to
accommodate the probe adapter. Refer to the Specifications chapter in this
manual for the required clearances.
The channel and clock probes shown in this chapter are for a 102/136-channel
module. Your probes will look different if you are using a 96-channel module.
The general requirements and restrictions of bus supports in the information on
basic operations show the vertical dimensions of a channel or clock probe
connected to square pins on a circuit board.
TMS 801 provides the following connection methods for probing the APIC bus:
H Connecting directly to the SUT
H Connecting to the SUT using a microprocessor probe adapter
H Connecting to the SUT using a microprocessor probe adapter and an
192-channel High-Density Probe.
Getting Started
Connecting Directly
to the SUT
To connect the logic analyzer directly to the SUT, follow these steps:
1. Turn off power to your SUT. It is not necessary to turn off power to the logic
analyzer.
CAUTION. Static discharge can damage the probe adapter, the podlets, or the
Module. To prevent static damage, handle all of the above only in a static-free
environment.
Always wear a grounding wrist strap or similar device while handling the bus
and probe adapter.
2. To discharge your stored static electricity, touch the ground connector located
on the back of the logic analyzer. Then, touch any of the ground pins of the
probe adapter to discharge stored static electricity from the probe adapter.
3. Connect the flying lead APIC bus interface cable to the probe adapter as
shown in Figure 1–1.

signal are located on the top of the probe adapter case.
NOTE. If your SUT does not have pin connections for the interface cables, you
can use KlipChip connectors to connect to appropriate IC pins. Refer to the
Replaceable Mechanical Parts List chapter for part number information.
