Operating basics
This section provides a brief description of the Tektronix P6910 General Purpose
Logic Analyzer Probe, probe accessories, probe labels, and probe accessory
connection instructions.
Product description
The P6910 probe is a 34-channel, general purpose probe that provides connections
from a Tektronix logic analyzer to the SUT (system-under-test).
The following list details the capabilities and qualities of the P6910 probe:
34 individual active channel connections
Differential and single-ended data, clock and qualification inputs
Lead set support for both single-ended and differential applications
Holder for 8-channel applications
Color-coded signal connectors
–2.5 V to +5 V input operating range
Minimal loading of <1 pF and 20 kΩto ground
Operation in normal or inverted polarity is acceptable
Any common mode voltage is acceptable as long as the maximum positive
voltage does not exceed +5 V and the maximum negative voltage does not
exceed –2.5 V
P6910 probe accessory information
The P6910 probe includes accessories to connect the logic analyzer to the SUT.
The following accessories are available for the P6910 probe:
Option 1K provides accessories for probing applications for less than
100 MHz. Tektronix recommends ordering two of each of the accessories
for a 34-channel probe. Details on the accessories are provided later in this
document. (See page 9, Option 1K accessories.)
Option 2K provides a probe accessory kit (Tektronix part number,
020-2973-01 or higher) for high-performance probing applications; provides
different means to connect the logic analyzer to the SUT. Tektronix
recommends ordering two accessory kits for a 34-channel probe. Details on
the accessory kit contents are provided later in this document. (See page 10,
Option 2K accessories.)

Probe labels, one sheet
P6910 General Purpose Logic Analyzer Probe Instruction Manual (Tektronix
part number, 077-0630-xx, available on the TLA Documentation CD or
downloadable from the Tektronix Web site: www.tektronix.com/manuals)
Probe label overview
The logic analyzer probe comes with a sheet of labels to apply to the probe before
connecting the probe to the instrument and SUT.
Tektronix provides a sheet of color-coded labels to apply to the probe to help
identify the connections to the logic analyzer and to the SUT. The label color is
designed to match the color of the probe connections on the logic analyzer. A set
of custom labels is also available for custom applications.
NOTE. If you are labeling probes for either 34- or 68-channel logic analyzers, use
a combination of two sets of probe labels for one of your probes. The labels for
this probe are grouped within a dashed red line. (See Figure 1 on page 3.)

Operating basics
Figure 1: Example of a sheet of P6910 probe labels
P6910 General Purpose Probe Instruction Manual 3

Operating basics
Apply the labels to the probe
Attach the labels to logic analyzer-end of the probe and to each of the four way
stations.
Attach the color-coded labels to the probe to help you identify the logic analyzer
and probe connections when connecting the probe to the SUT.
1. Determine the channel groups that you plan to use on your logic analyzer and
identify the matching labels.
Refer to the logic analyzer to identify the number of probe connections
(dependent on the number of channels on the instrument) and the channel
color-coding that corresponds to the provided sheet of probe labels.
2. Identify the logic analyzer end of the probe. (See Figure 2 on page 5.)
3. Using a pair of flat-nosed tweezers, place the tip of the tweezers under the
upper right corner of the logic analyzer-end label.
This will be the largest label of the five labels. Grasp the corner of the label
and lift the label up and toward you.
4. Carefully align the label to the label indent located on the top of the logic
analyzer-end and apply the label.
5. Identify the four way stations. (See Figure 2 on page 5.)
Note that the logic analyzer end label contains two colors. From the logic
analyzer end follow one of the two colors down the length of the cable to
the way station.
6. Using a pair of flat-nosed tweezers, place the tip of the tweezers under the
upper right corner of the matching color-coded way station.
Grasp the corner of the label and lift the label up and toward you.
7. Carefully align the label to the label indent located on the top of the way
station and apply the label.
8. Repeat step 7 for the second way station of the same color (but different label
shape).
9. Repeat the above steps for the other logic analyzer-end label colors.
After applying the labels to the probes, you are ready to connect the probes to
the logic analyzer.

Operating basics
Figure 2: Attaching the probe labels
P6910 General Purpose Probe Instruction Manual 5

Operating basics
Connect the probe to the instrument
The P6910 probe connects a TLA6200 Series logic analyzer or TLA7000 Series
logic analyzer with TLA7Axx or TLA7Bxx logic analyzer modules to the SUT.
Apply the labels to the probes before connecting the probes to the instrument
and to the SUT.
Connect the probes to the logic analyzer using the following steps:
1. Match the color-coded labels of the probe to the same color-coded connector
on the logic analyzer. (See Figure 3 on page 7.)
2. Identify the beveled edges of the connector inside the logic analyzer end
of the probe.
3. Align the beveled edges of the connector to its mating connector on the logic
analyzer and press into place.
4. Evenly tighten both screws on the logic analyzer end of the probe until they
are snug.
Tighten each screw to 4 in-lbs (max).
CAUTION. When attaching the probe to the logic analyzer, use care to evenly
tighten probe screws until they are snug. Under-tightening the probe screws can
result in intermittent operation. Over-tightening can result in stripped screws.
NOTE. The P6910 probe can be connected to the logic analyzer when it is
powered on. The probe head can also be connected to the SUT without turning
the power off.
