2P6434 Probe Instructions
LabelsThe 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.
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.

Probe Pin 1 side Color Pin 38 side Color
ACK:0, A3:7-0, A2:7-0 Tan CK:1, A1:7-0, A0:7-0 Orange
DQUAL:0, D3:7-0, D2:7-0 Blue CK:2, D1:7-0, D0:7-0 Yellow
CCK:3, C3:7-0, C2:7-0 White QUAL:1, C1:7-0, C0:7-0 Gray
EQUAL: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.
