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 processor 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
processor 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 1–1. This prevents the circuit board from flexing and the
socket pins from bending.
4. Remove the processor from your SUT.
5. Line up the pin A1 indicator on the probe adapter board with the pin A1
indicator on the processor.

7. Connect the channel and clock probes to the probe adapter as shown in
Figure 1–2. Match the channel groups and numbers on the probe labels to the
corresponding pins on the probe adapter. Match the ground pins on the
probes to the corresponding pins on the probe adapter.

8. Line up the pin A1 indicator on the probe adapter board with the pin A1
indicator on your SUT.
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.

To connect the logic analyzer to a SUT using a PQFP probe adapter, follow these
steps:
NOTE. The PQFP probe adapter connects to the primary bus only. There are no
connections to the expansion bus.
10. Turn off power to your SUT. It is not necessary to turn off the logic analyzer.
CAUTION. Static discharge can damage the processor, the probe adapter, the
probes, or the module. To prevent static damage, handle all the above only in a
static-free environment.
Always wear a grounding wrist strap or similar device while handling the
processor and probe adapter.
11. 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.
