The logic analyzer probe comes with a shee t 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.

Apply the labels to the p robe
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 a nd 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.

Connect the pr
obe 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
lt in intermittent operation. Over-tightening can result in stripped screws.

Use the clock and qualifier probe connections from the SUT to define how the
logic analyzer stores data.
Every logic analyzer has some-special purpose input channels. Inputs designated
as clocks can cause the logic analyzer to store data. Qualifier channels can be
logically
from the SUT. Routing the appropriate signals from the design to these inputs
ensures that the logic analyzer can acquire data correctly. Unused clocks can be
used as qualifier signals.
Depending on the channel width, each logic analyzer will have a different set of
clock and qualifier channels. The following table shows the availability of the
clock and qualifier channels.

Sin
double-probe these signals for timing analysis. When switching from state to
timing analysis modes, all of the clock and qualifier signals will be visible. This
also allows you to route regular signals, those not needed for clocking, to these
channels when they are not being used for their special purpose.
It is a good practice to take advantage of these channels to increase your options
for when you will latch data. Routing several of your design's clocks and strobes
to the logic analyzer clock inputs will provide you with a greater flexibility in the
logic analyzer clocking setup menus.
As an example, look at a processor with a ma ster clock, a data strobe, and an
address strobe. Routing all three of these signals to the logic analyzer clock inputs
will enable you to latch data on the processor master clock, only when data is
strobed, or only when address is strobed. Some forethought in signal routing can
greatly expand the ways to latch and analyze data.
P6910 General Purpose Probe Instruction Manual 17
Reference
A processor als
o provides a good example of signals that can be useful as
qualifiers. There are often signals that indicate data reads versus data writes
(R/W), signals that show when alternate bus masters have control of the processor
buses (DMA), and signals that show when various memory devices are being
used (ChipSel). All of these signals are good candidates for assignment to
qualifier channels.
By logically AND'ing the clock with one of these qualifiers you can program the
logic analyzer to store only data reads or data writes. Using the DMA signal as a
qualifier p
rovides a means of filtering out alternate bus master cycles. Chip selects
can limit data latching to specific memory banks, I/O ports, or peripheral devices.

When demultiplexing data there is no need to connect the destination channels to
the multiplexed bus. Data from the source channels are routed to the d estination
channels internal to the logic analyzer.
Demultiplexing affects only the main memory for the destination channels. This
means that the MagniVu memory is filled with data from whatever is connected to
the demultiplexing destination channel probe inputs. This provides an opportunity
to acquire high resolution MagniVu data on a few extra channels. Connecting the
demultiplexing destination channels to other signals will allow viewing of their
activity in the MagniVu memory but not the main memory.

Range recognizers
When using range recognizers, probe groups and probe channels must be in
hardware order.
Probe groups must be used from the most-significant probe group to the
least-significant probe group based on the following order:
C3 C2 C1 C0 E3 E2 E1 E0 A3 A2 D3 D2 A1 A0 D1 D0 Q3 Q2 Q1 Q0
CK3 CK2 CK1 CK0
Probe channels must be from the most-significant channel to the least-significant
channel based on the following order:
76543210
The above example assumes a 136-channel logic analyzer. The missing channels
in instruments with fewer than 136 channels are ignored. With merged modules,
range recognition extends across the first three modules: the master module
contains the most-significant channels.

Probe signal names
Use signal names to simplify probe connections to the logic analyzer.
Refer to the following tables for information on signal connections. Match the
alpha character that precedes the channel identifier (for example, E3:7) to the
probe head label.
All differential data and clock/qualifiers on the probe may have the negative input
pin grounded and be used as a single-ended input.
You can find more information on 2X and 4X demultiplexing channel assignments
in the Demultiplexing Information section. (See Table 2 on page 18.) (See Table 3

Load models
Load models are important electrical considerations when working with the
P6910 probe.
The low frequency model is typically adequate for rise and fall times of 1 ns
or greater in a typical 25 Ω source impedance environment (50 Ω runs with a
pass-through connection). For source impedance outside this range, and/or rise
and fall times less than 1 ns, use the high frequency model to determine if a
significan
t difference is obtained in the modeling result.
The following electrical model displays a single podlet load model of the probe.
(See Figu
re 14.)
