Getting Started

Information on basic operations also contains a general description of supports.

Logic Analyzer Software Compatibility

The label on the microprocessor support floppy disk states which version of logic
analyzer software the support is compatible with.

Logic Analyzer Configuration

To use the 80286 support, the Tektronix logic analyzer must be equipped with at
least a 102-channel module, a 96-channel module. The module must be equipped
with enough probes to acquire channel and clock data from signals in your
80286-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 microprocessor
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 80286 support requirements
and restrictions.

for information on how to remove power from the probe adapter.

Configuring the Probe Adapter

The probe adapter does not require any configuration.

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
microprocessor to accommodate the probe adapter. Refer to the Specifications
chapter in this manual for the required clearances.

PGA Probe Adapter

The channel and clock probes shown in this chapter are for a 102-channel
module. Your probes will look different if you are using a 96-channel module.

The general requirements and restrictions of microprocessor supports in the
information on basic operations shows the vertical dimensions of a channel or
clock probe connected to square pins on a circuit board.

To connect the logic analyzer to a SUT using a PGA probe adapter, 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 microprocessor, the probe adapter,
the probes, 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
microprocessor and probe adapter.

Getting Started

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. Place the probe adapter onto the antistatic shipping foam to support the probe

as shown in Figure 1–1. This prevents the circuit board from flexing and the

9. Place the probe adapter onto the SUT as shown in Figure 1–3.

NOTE. You might need to stack one or more replacement sockets between the SUT
and the probe adapter to provide sufficient vertical clearance from adjacent
components. However, keep in mind that this might increase loading, which can
reduce the electrical performance of your probe adapter.

Figure 1–3: Placing a PGA probe adapter onto the SUT

To connect the logic analyzer to a SUT using a PLCC probe adapter, follow these
steps:

1. Turn off power to your SUT. It is not necessary to turn off the logic analyzer.

CAUTION. Static discharge can damage the microprocessor, the probe adapter,
the probes, 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
microprocessor 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. Place the probe adapter onto the antistatic shipping foam to support the probe

as shown in Figure 1–4. This prevents the circuit board from flexing.

4. Remove the microprocessor from your SUT.

You can use channel probes, clock probes, and leadsets with a commercial test
clip (or adapter) to make connections between the logic analyzer and your SUT.

To connect the probes to 80286 signals in the SUT using a test clip, 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 microprocessor, the probes, 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
microprocessor.

2. To discharge your stored static electricity, touch the ground connector located

on the back of the logic analyzer. If you are using a test clip, touch any of the
ground pins on the clip to discharge stored static electricity from it.

CAUTION. Failure to place the SUT on a horizontal surface before connecting the
test clip might permanently damage the pins on the microprocessor.

3. Place the SUT on a horizontal static-free surface.

4. Use Table 1–3 to connect the channel probes to 80286 signal pins on the test

clip or in the SUT.
Use leadsets to connect at least one ground lead from each channel probe and

the ground lead from each clock probe to ground pins on your test clip.
