TMS 420 R3051, R3052 & R3081 Microprocessor Support Instruction Manual 

1–5

Probe adapter

Channel probe

and podlet holder

Foam

Hold the channel probes by the podlet
holder when connecting them to the
probe adapter. Do not hold them by
the cables or necks of the podlets.

Clock probe

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.
