SUT Power. Whenever the SUT is powered off, be sure to remove power from the
probe adapter. Refer to Applying and Removing Power at the end of this chapter
for information on how to remove power from the probe adapter.
Disabling the Data, Instruction, and Vector Caches. You must disable the internal
Data, Instruction, and Vector caches. Disabling the caches make most instructions visible on the bus so the logic analyzer can acquire and disassemble them.
Configuring the Probe Adapter
The i960 Hx microprocessor uses the high-order four address lines to define 16
memory regions. The characteristics of each region is set up by software at
power-up. You must set the DIP switches on the probe adapter to match the
software settings of each memory region.
All the switches are open when the probe adapter is shipped; READY# and
BTERM# are always monitored in all the memory regions until you change the
settings. Figure 1–1 shows the location of the DIP switches on the probe adapter.

TMS 164 i960 HX Microprocessor Support Instruction Manual
Connecting to a System Under Test
Before you connect to the SUT, you must connect the standard 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 Specifica-
tions chapter in this manual for the required clearances.
The clock and channel probes shown in the connection figures are for the 92A96
module. If you are using a different module, your probes will look different than
those shown.
The Requirements and Restrictions description in the basic operations user
manual shows the vertical dimensions of an acquisition probe connected to
square pins on a circuit board.
If a probe adapter has one or two high-density cables (probe adapter does not
have pins to which the clock and channel probes connect), it requires an
LAHDP2 probe to make connections between the logic analyzer and a SUT.
To connect the logic analyzer to a SUT using a PGA probe adapter and an
LAHDP2 probe, follow these steps:
Getting Started
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 low-profile probe
adapter, the acquisition 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 low-profile probe adapter.
2. To discharge your stored static electricity, touch the ground jack located on
the back of the logic analyzer. Then, touch the black foam on the underside
of the probe adapter to discharge stored static electricity from the probe
adapter.
3. Remove the microprocessor from the SUT.
4. Line up the pin A1 indicator on the probe adapter board with the pin A1
indicator on the microprocessor.
CAUTION. Failure to correctly place the microprocessor into the probe adapter
may permanently damage the microprocessor once power is applied.

6. Remove the black foam from the underside of the probe adapter.
7. Line up the pin A1 indicator on the probe adapter board with the pin A1
indicator on the SUT.
8. Place the probe adapter onto the SUT as shown in Figure 1–3.
NOTE. You may 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 this may increase loading, which can reduce
the electrical performance of the probe adapter.

9. Connect the clock and channel probes to the LAHDP2 probe as shown in the
basic operations user manual.
10. Align pin 1 on the LO cable connector, the end on the narrowest cable strip
of the cable, with pin 1 on the LO connector on the LAHDP2 probe. Connect
the cable to the connector as shown in Figure 1–4.

Applying and Removing Power
A power supply for the TMS 164 i960 Hx probe adapter is included with the
product. The power supply provides +5 V power to the probe adapter. When the
power supply is on, the LED indicator is lit. The center connector of the power
jack connects to Vcc.
NOTE. Whenever the SUT is powered off, be sure to remove power from the probe
adapter.

Getting Started
To apply power to the i960 Hx probe adapter and SUT, follow these steps:
CAUTION. Failure to use the +5 V power supply provided by Tektronix may
permanently damage the probe adapter and i960 Hx microprocessor. Do not
mistake another power supply that looks similar for the +5 V power supply.
1. Connect the +5 V power supply to the jack on the probe adapter. Figure 1–5
shows the location of the jack on the adapter board.
CAUTION. Failure to apply power to the probe adapter before applying power to
your SUT may permanently damage the i960 Hx microprocessor and SUT.
2. Plug the power supply for the probe adapter into an electrical outlet. The
power LED should light up.
3. Power on the SUT.
