P6434 Probe Instructions
Operating Basics
Product Description
The P6434 Mass Termination Probe allows you to connect 34 logic analyzer
channels to a microprocessor probe adapter or directly to your SUT in one fourth
the physical area needed to connect standard probes. The vertical clearance
dimension is less than a half inch when used with the Low-Profile Extender.
To connect directly to your SUT, you must include compatible Mictor connectors
in your circuit board design. To do this, be sure you understand the requirements
and conform to the guidelines for designing an interface in these instructions.
This section contains information on the following topics and tasks:
H Product description
H Applying labels
H Connecting probes to and disconnecting probes from a SUT
The P6434 probe can acquire data from 32 input/output signals and two clock,
one clock and one qualifier, or two qualifier signals.
The probe has connectors on each end. One end is called the probe tip and
connects to your SUT. The other ends are called the module ends and connect to
the logic analyzer. Figure 1 shows the P6434 probe.

Operating Basics
Labels
The P6434 probe is shipped with a sheet of labels. The labels are color coded to
match the probe connectors on the logic analyzer and are different shapes for the
probe tip and module ends of the probe.
There are two methods you can use to apply labels to the P6434 probe: standard
or custom. You need to decide which method to follow prior to applying labels.
If you are using P6434 probes with a TMS probe adapter, be sure to check the
TMS instruction manual before applying labels to see which method to use.
Standard Method
Custom Method
Applying
Microprocessor support packages or your SUT signal and channel assignments
can follow the standard labeling scheme for P6434 probes. Table 1 shows the
standard channel combinations for the probes.

E QUAL:3, E3:7-0, E2:7-0 Green QUAL:2, E1:7-0, E0:7-0 Violet
With the custom method, the probe labels depend on the logic analyzer module
being used or the probe sections assigned to each P6434 probe.
You must attach a pin 1 label to the pin 1 side of the probe and a pin 38 label to
the pin 38 side. If necessary, the sheet of labels includes blanks you can use to
create your own pin 1 and pin 38 side labels.
To apply labels to the probe, follow these steps:
1. Locate the small pin 1 recess on the probe tip and apply a pin 1 label on that
side. See Figure 2.
2. For standard labeling as listed in Table 1, apply the associated label to the
pin 38 side of the probe tip.
For custom labeling, be careful not to use two labels with the pin 1 indicator
or two labels without a pin 1 indicator on a single probe.
3. Match the color of the module end labels to the probe tip labels and apply.
The module end labels go on the nonkeyed case half.

Connecting the P6434 Probe to the SUT
The P6434 probe can connect to surface-mounted or straddle-mounted Mictor
connectors. You can use the Low-Profile Extender (available as an optional
accessory) to connect the probe to systems with as little as a half inch of
clearance between circuit boards. You can also install optional latch housings
around the connector to provide positive retention of the probe.
In the following procedures, a surface-mounted Mictor connector is shown in the
figures. These procedures are the same for the straddle-mounted connector.
Direct Connection
To connect the P6434 probe to a Mictor connector in your SUT (or on a TMS
probe adapter), follow these steps:
1. Line up the pin 1 indicator on the probe tip with pin 1 on the connector in
your SUT. The Mictor connector is keyed to prevent incorrect connections.
CAUTION. To avoid damaging the probe and SUT, always position the probe
perpendicular to the mating connector and gently connect the probe. Incorrect
handling of the probe while connecting it to the SUT can result in damage to the
P6434 probe or to the mating connector in the SUT.

2. Position the probe tip perpendicular to the mating connector, and gently
connect the probe as shown in Figure 3.
3. When connected, push down the latch releases on the probe to set the latch.

Low-Profile Extender
Connection
You can use the Low-Profile Extender to connect the P6434 probe to systems
with as little as a half inch of clearance between circuit boards. The extender
connects to Mictor connectors with or without a latch housing.
To connect the probe using the extender, follow these steps:
1. Line up the pin 1 indicator on the low-profile end of the extender with pin 1
on the connector in your SUT. The Mictor connector is keyed to prevent
incorrect connections.
2. Position the low-profile end perpendicular to the connector and gently
connect the extender as shown in Figure 4.
3. To connect the P6434 probe to the other end of the extender, follow the
Direct Connection procedure on page 3.
