P6434 Probe Instructions
Operating Basics
The P6434 Mass T ermina tion Probe allows you to connect 34 logic analyzer
channels to a microprocessor probe adapter or directly to your target system in
one fourth the physical area needed to connect standard probes.
You can reduce the vertical clearance dimension to less than a half inch if you
use the low-profile extender. If you use a P6434 Reduced Bias Voltage adapter,
you can reduce the pull-up voltage that the P6434 probe delivers to the system
under test. The pull-up voltage reduces from 2.2 volts to 1.1 volts at the same
time the DC input resistance changes from 20 kΩ to 10 kΩ. If you are using
TLA6xx or TLA7Lx/Mx/Nx/Px/Qx logic analyzer modules you can take
advantage of the new compression footprint and eliminate the need for Mictor
connectors in your target system with a Compression-on-PCB to P6434 Mictor
adapter.
Without a Compression-on-PCB to P6434 Mictor adapter, you must include
compatible Mictor connectors in your circuit board design to connect directly to
your target system. To do this, be sure you understand the requirements and
conform to the guidelines for designing an interface in these instructions. For
additional information on designing an interface see the 071-1059--xx P6810,
P6860, and P6880 Logic Analyzer Probes Instruction Manual.

Product Description
The P6434 probe can acquire data from 32 input/output signals and two clocks,
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 target system. The other ends are called the module ends and
connect to the logic analyzer. Figure 1 shows the P6434 probe.

Labels
Operating Basics
The P6434 probe labels are color coded to match the probe connectors on the
logic analyzer. The P6434 probe is shipped with a sheet of labels, a Read This
First sheet, and a P6434 Instructions Manual.
Color Coded Labels
The Table 1 labeling scheme for P6434 probes occurs on most microprocessor
support packages and target systems for signal and channel assignments.
NOTE. Use one Pin 1 label for each probe connector. Do not use two labels with
a pin 1 indicator or two labels without a pin 1 indicator on a single probe.

Operating Basics
Applying Labels
To apply labels to the probe, follow these steps:
1. Locate the labels you need for the P6434 probe from the provided sheet of
labels, but do not peel them off yet. If you need help determining which
labels to use, see steps a and b.
a. Look at the logic analyzer module and determine which channel group
you want to connect the P6434 probe to.
b. Look at the sheet of labels and locate the labels that match the logic
analyzer channel group you need to use. Notice that there are two
different sizes of labels for each channel group.
H Probe-tip labels (smaller)
H Module-end labels (larger)
H Blank labels (custom channel combinations not recommended)
2. Locate the probe-tip end of the P6434 connector (see Figure 2).

3. Locate the pin 1 side of the probe-tip connector by using Figure 3 (end view
of the probe-tip connector).

Connecting the P6434 Probe to the Target System
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.
Operating Basics
Direct Connection
To connect the P6434 probe to a Mictor connector in your target system (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 target system. The Mictor connector is keyed to prevent incorrect
connections.
CAUTION. To avoid damaging the probe and target system, always position the
probe perpendicular to the mating connector and gently connect the probe.
Incorrect handling of the probe while connecting it to the target system can
result in damage to the P6434 probe or to the mating connector in the target
system.
NOTE. If you have custom channel combinations for the mictor connector on your
target system, use the blank sheet of labels to create your own pin 1 and pin 38
side labels.
Use one Pin 1 label for each probe connector. Do not use two labels with a pin 1
indicator or two labels without a pin 1 indicator on a single probe.
Custom labeling is an option, though not recommended.
