P6450 Labels
Use the following instructions to attach probe labels to your Tektronix P6450
Logic Analyzer Probe.
NOTE. Always use flat-nosed tweezers to remove the labels from the sheet of
labels. Never peel labels with your fingers. The labels are made of soft vinyl and
can stretch and distort easily. To avoid stretching the label, always grasp it from
the top right corner while removing it from the sheet of labels.
The adhesive on the vinyl labels is extremely strong. Carefully align each label
to the intended outline on the module end and probe head before attaching it to
the probe. Once labels are placed on the probe, they become very difficult to
remove.
You will be attaching labels to the logic analyzer end and both sides of the probe
head. Refer to Figure 2 and use the following steps to attach the probe labels:
1. Identify the module end of the probe cable.
2. From the sheet of labels, locate the color-coded label for the logic analyzer
end of the probe cable.
3. Attach the matching colored labels to the probe head on the other end of the
probe cable.

Operating Basics
Connecting the Probes to the Target System
You can connect the P6450 probe to the target system without turning off the
power to the target system. The target system must have the probe retention
assembly installed. Installation procedures are described on the following pages.
Cleaning the
Compression Footprints
Using the Probe Retention
Assembly
The following procedure is recommended to obtain best performance.
CAUTION. To avoid electrical damage, always power off your target system
before cleaning the compression footprint.
Prior to connecting the probe to the target system, the compression footprints on
the board should be properly cleaned, according to the following steps:
1. Use a lint-free, clean-room cloth lightly moistened with electronic/reagent
grade isopropyl alcohol, and gently wipe the footprint surface.
2. Remove any remaining lint using a nitrogen air gun or clean, oil-free dry air.
The probe retention assembly provides a housing around the connector footprint
to help stabilize the probe. To install the probe retention assembly on the circuit
board, refer to Figure 4 on page 7 and do the following:
1. Locate the correct footprint. If you intend to use multiple probes, your PCB
has multiple footprints. Be careful to select the correct one.
2. Clean the compression footprint as described above.
3. Align the retention assembly over the footprint so that the keying pin on the
retention assembly lines up with the keying pin hole on the footprint.
4. Insert the retention assembly into the holes in the footprint on the PCB.
NOTE. The following two steps are important to ensure that the retention
assembly is correctly mounted and that the probe makes proper contact with the
PCB.
5. Hold the retention assembly so that it is firmly flush with the surface of the
footprint, and the four anchoring posts extend through the circuit board to
the opposite side.
6. Using a pair of needle--nose pliers, grasp one of the posts. Using the circuit
board hole as a fulcrum, bend the post outward so that it is flush with the
PCB surface, anchoring the assembly to the PCB. Bend the other three posts
in the same manner.
7. Solder the anchoring posts to the PCB.

Handling the cLGA
Interface Clip
(Probe Head)
The cLGA interface clip in the probe head should always be handled with care.
Keep the following points in mind when you handle the clip:
H Always handle the cLGA interface clip by the outer edges, and be careful to
avoid the contacts in the center. Do not touch the contacts with your fingers,
tools, wipes, or any other devices. See Figure 5.
Figure 5: Proper handling of the interface clip
H Do not expose the connector to liquids or dry chemicals.
H If the board pad array needs to be cleaned, only use isopropyl alcohol and
lint-free cloth as described above.
H Immediately following cleaning, or immediately prior to placement of
connector to circuit board, blow off the board pad array and connector
contact array with clean, oil-free dry air or nitrogen to remove loose debris.
First start the blowing process by aiming away from the array areas, and then
sweep across the pad and contact arrays in a repeated motion to remove
loose debris.
H Place the connector onto the board pad array using the bosses or locator pins
for alignment. Use care to prevent incidental contact with other surfaces or
edges in the connector contact array area prior to board placement.
H Always store the probe head in the protective cover when not in use.
See Figure 8 on page 12.

Note: The retention assembly is visually keyed
(one side is black and one side is silver).
Figure 6: Connecting the probes to the target system
2. Start both screws in the retention assembly, and tighten them evenly to
ensure that the probe approaches and mates squarely to the PCB. If access is
limited, use the adjustment tool that came with your probe. The probe is
completely fastened to the PCB when the screws stop in the assembly.
3. Verify that all of the channels are functional. If any channels appear to be
nonfunctional, see Troubleshooting Probe Connections to the SUT on
page 10.

Operating Basics
Troubleshooting Probe
Connections to the SUT
The most obvious symptom of a problem with the probe installation is seeing
incorrect data in the logic analyzer acquisition. However, the nature of the
incorrect data has a very consistent characteristic; the data from multiple
channels go to a logic low and stay there. Intermittent bad data, or a single dead
channel are not failures typically associated with probe installation problems.
1. Slightly move the probe head to either side, or press down on the probe head
while making new acquisitions. If good data is now being acquired, then the
probe mounting is most likely the cause.
2. If good data is not acquired, then remove the probe and check the retention
assembly for too much play. If there is significant play, then the probe
mounting is most likely the cause.
3. If the retention assembly has minimal play and you cannot see a gap between
the bottom of the assembly and the circuit board surface, then move the
probe with bad data from one logic analyzer probe location to another.
4. If the problem follows the probe, then the probe is the problem. Visually
inspect the cLGA interface clip on the probe for any damage or missing
c-spring metal contacts.
If there is damage to the interface clip, or if any c-spring metal contacts are
missing, replace the cLGA interface clip. (See Replacing the cLGA Clip on
page 30 and Replaceable Parts, beginning on page 33 for more information.)
5. If the problem doesn’t follow the probe, it is either the logic analyzer or the
probe connection at its previous location. Move the probe back to the
original location to be certain it was not a connection problem at the logic
analyzer end.
6. Place another probe in the retention assembly of the original probe. If the
new probe acquires data, then the old probe is probably at fault.

This section provides reference information for the P6450 High-Density Probe
with D-Max probing technology.
Designing an Interface Between the Probes and a Target System
Once you have determined which probe is required, use the following information to design the appropriate connector into your target system board.
Signal Fixturing
This section contains information to consider for signal fixturing.
Considerations
Clocks and Qualifiers. 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 ANDed and ORed with clocks to further
define when the logic analyzer should latch data from the system under test.
Routing the appropriate signals from your 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 TLA5000B Series logic analyzer will
have a different set of clock and qualifier channels. Table 2 shows the clock and
qualifier channels available for each module.
Table 2: Logic analyzer clock and qualifier availability
Clock Inputs Qualifier Inputs

TLA5203B n n n n n n
TLA5204B n n n n n n n n
CLK:0
CLK:1 CLK:2 CLK:3 QUAL:0 QUAL:1 QUAL:2 QUAL:3
All clock and qualifier channels are stored. The logic analyzer always stores the
logic state of these channels every time it latches data.
Since clock and qualifier channels are stored in the logic analyzer memory, there
is no need to double probe these signals for timing analysis. When switching
from state to timing analysis, all of the clock and qualifier signals will be visible.
P6450 High-Density Logic Analyzer Probe Instruction Manual
13
Reference
This allows you to route signals not needed for clocking to the unused clock and
qualifier channels.
It is a good practice to take advantage of the unused clock and qualifier channels
to increase your options for when you will latch data. Routing several clocks and
strobes in your design to the logic analyzer clock inputs will provide you with a
greater flexibility in the logic analyzer Setup menu.
As an example, look at a microprocessor with a master clock, data strobe, and an
address strobe. Routing all three of these signals to 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 in which you can latch and analyze data.
A microprocessor also 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 ANDing 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 provides 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.

Demultiplexing Multiplexed Buses. TLA5000B Series logic analyzers support 2X
demultiplexing. Each signal on a dual multiplexed bus can be demultiplexed into
its own logic analyzer channel. See Table 3 to determine the correct channel
groups to use.

Destination channels receiving target system test data
TLA5204B TLA5203B TLA5202B TLA5201B
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 destination
channels internal to the logic analyzer. Table 3 shows the mapping of source
channels to destination channels.
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.
P6450 High-Density Logic Analyzer Probe Instruction Manual

Reference
High Resolution Timing. The high resolution timing mode provides double the
normal 500 MHz sample rate on one-half of the channels. By trading half of the
analyzer’s channels, the remaining channels can be sampled at a 1 GHz rate with
double the memory depth.
By taking care to assign critical signals to the demultiplexing source channels,
you can obtain extra timing resolution where it is most needed. Since
demultiplexing affects only the main memory you will still have the MagniVu
data available for all of the signals that are disconnected from the main memory
when you switch to the high resolution timing modes.
Range Recognition. When using range recognizers, the 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 examples assumes a 136-channel logic analyzer. The missing
channels in logic analyzers with fewer than 136 channels are ignored.

Mechanical
Considerations
This section provides information on compression footprint requirements and
physical attachment requirements.
The PCB holes, in general, do not have an impact upon the integrity of your
signals when the signals routed around the holes have the corresponding return
current plane immediately below the signal trace for the entire signal path from
driver to receiver.
NOTE. For optimum signal integrity, there should be a continuous, uninterrupted
ground return plane along the entire signal path.

Electrical Considerations
This section provides information on transmission lines and load models for the
P6450 probe.
The low-frequency model is typically adequate for rise and fall times of 1 ns or
slower 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 faster than 1 ns, use the high-frequency model to determine if a
significant difference is obtained in the modeling result.
The compression land pattern pad is not part of the load model. Make sure that
you include the compression land pad in the modeling.
Transmission Lines. Due to the high performance nature of the interconnect,
ensure that stubs, which are greater than 1/4 length of the signal rise time, are
modeled as transmission lines.

Probe Footprint Dimensions
Use the probe footprint dimensions in Figure 16 to lay out your circuit board
pads and holes for attaching the retention posts. If you are using the alternate
retention assembly, all dimensions remain the same as shown below, except the
overall length and width. (Refer to Figure 10 on page 18.) Pad finishes that are
supported include immersion gold, immersion silver, and hot air solder level.
All dimensions are per standard IPC tolerance, which is ±0.004 in.
NOTE. Tektronix recommends using immersion gold surface finish for best
performance.
Tektronix also recommends that the probe attachment holes float or remain
unconnected to a ground plane. This prevents overheating the ground plane and
promotes quicker soldering of the retention posts to your PCB. The probe
retention posts are designed to allow you to solder the retention posts from either
side of your PCB.

Other Design Considerations
Reference
Via-in-pad
Traditional layout techniques require vias to be located next to a pad and a signal
routed to the pad, causing a stub and more PCB board area to be used for the
connection. Many new digital designs require you to minimize the electrical
effects of the logic analyzer probing that you design into the circuit board.
Using via-in-pad to route signals to the pads on the circuit board allows you to
minimize the stub length of the signals on your board, thus providing the
smallest intrusion to your signals. It also enables you to minimize the board area
that is used for the probe footprint and maintain the best electrical performance
of your design.
Figure 17 shows a footprint example where two pads use vias. Detail A describes
the recommended position of the via with respect to the pad.
All dimensions are per standard IPC tolerance, which is ±0.004 in.
