Attaching Probe Labels
When you purchase one or more P6419 logic analyzer probes with a TLA520x
logic analyzer mainframe or TLA7Nx/Px/Qx logic analyzer module, all labels
are already attached. If you purchase the probe seperately from the logic
analyzer, you must apply the color-coded labels as described in this section. The
labels help you identify the probe connections at the logic analyzer end and at
the target system end.
Table 1 lists the probe section and label color combinations. Refer to Table 1 and
to Figure 5 when you attach the probe labels.

P6419 Labels
Use the following instructions to attach probe labels to your Tektronix P 6419
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 ar e 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 module and and both sides of the probe head.
Refer to Figure 5 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 module 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
Mictor-on-PCB to
Compression Adapter
The Mictor-on-PCB to compression adapter allows existing applications of older
logic analyzer modules and probes to connect to the compression footprint. You
can connect the adapter to the target system without turning off the target system.
Connect the adapter according to the following steps:
NOTE. Be sure to use a thin elastomer holder. The thin elastomer is black and
does not have the protruding rib (see Figure 10).
1. While holding the first probe end at a perpendicular angle to the adapter,
place the probe end into the adapter and finger-tighten the screws until snug,
not to exceed 1 in-lbs.
2. Connect the second probe end to the adapter in the same manner.
3. Press the connected probe ends and adapter into the existing Mictor
connector on the PCB.
This adapter supports standard Mictor connector footprints and signal connections on older logic analyzer designs.
The Mictor adapter adds 2.7 pF to the high-density compression probe load of
0.7 pF for a combined adapter and probe capacitance load of 3.4 pF.
Connecting the
Compression-on-PCB to
P6434 Mictor Adapter
The Compression-on-PCB to P6434 Mictor adapter (see Figure 3 on page 3)
allows you to connect the compression footprint to the Mictor connector pins
used by the P6434 Probe. You can connect the adapter to the target system
without turning off the target system. Connect the adapter according to the
following steps:
NOTE. To use this adapter, do not install press-in nuts. However if board
thickness is >.093 in, you will need to install press-in nuts before migrating to
P6419 probes.
1. Place the adapter at a perpendicular angle on top of the compression
footprint.
2. Place the backing plate on the underside of the PCB.
3. Connect the backing plate by sliding the two screws into the existing screw
holes from the underside of the PCB and finger-tighten the screws until
snug, not to exceed 1 in-lbs (typically, 1/2 in-lbs. You are encouraged to use
a torque wrench to ensure proper tightness of probe head screws.

Operating Basics
CAUTION. When attaching the probe head to the target system, you must use care
to evenly tighten probe head screws until they are snug. First slightly tighten
both screws, then snug each screw to 1 in-lbs (max). Under-tightening the probe
head screws can result in intermittence. Over-tightening can damage the
elastomer holder and strip the screws.
4. Plug the P6434 Probe into the adapter.
Screws of two different lengths are provided to attach the adapter to your PCB.
The length of screw you need depends on the thickness of the P CB (0.050 in to
0.250 in).
This adapter requires use of the Compression-on-PCB to P6434 Mictor adapter
land footprint. For further dimensional information, refer to the Compression-onPCB to P6434 Mictor adapter land footprint (see Figure 15 on page 33).

H Specifications
Designing an Interface Between the P6419 Probe 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. The
following topics are in this section:
H Signal fixturing considerations
H Signal connections (signal names and land footprint)
H Mechanical considerations
H Electrical considerations
Signal Fixturing
Considerations
This section contains the following information to consider for signal fixturing:
H Clocks and qualifiers
H Merged modules and source synchronous clocking
H Demultiplexing multiplexed buses
H 2X high resolution timing modes (Internal 2X)
H 4X high resolution timing modes (Internal 4X -- TLA520x logic analyzer
mainframes only)
H Range recognition
Clocks and Qualifiers. Every logic analyzer has some special purpose input
channels. Inputs designated as clocks can cause the analyzer to store data.
Qualifier channels can be logically AND’ed and OR’ed with clocks to further
define when the analyzer should latch data from the system under test. Routing
the appropriate signals from our design to these inputs will ensure that the
analyzer can acquire data correctly.

Depending on the channel width, each TLA520x mainframe, TLA6xx mainframe, and TLA7Lx/Mx/Nx/Px/Qx module will have a different set of clock and
qualifier channels. Table 2 shows the clock and qualifier channels available for
each instrument.

All clock and qualifier channels are stored. The analyzer stores the logic state of
these channels every time it latches data.
Since clock and qualifier channels are stored in the logic analyzer’smemory,
there is no need to double probe these signals for timing analysis. When
switching from state to timing analysis modes, all of the clock and qualifier
signals are 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.
16
It is 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 provides you with greater flexibility in the
logic analyzer clocking setup menus.
As an example, look at a microprocessor with a master clock, data strobe, and an
address strobe. Routing all three of these signals to analyze clock inputs enables
you to latch data on the processor master clock, only when data is strobes or only
when address is strobed. Some forethought in signal routing can greatly expand
the ways in which you can latch and analyze data.
P6419 Logic Analyzer Probe Instructions
Reference
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 AND’ing the clock with one of these qualifiers, you can program
the 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. TLA7Nx/Px/Qx modules and TLA6xx
mainframes support 2X demultiplexing. However, only TLA520x mainframes
support 4X demultiplexing. Each signal on a dual multiplexed bus can be
demultiplexed into its own logic analyzer channel. See Table 3 and Table 4 to
determine which channel groups to connect to feed channels in the target system
the test data.

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 and Table 4 show the
mapping of source channels to destination channels.
18
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.
2X and 4X High Resolution Timing Modes. 2X high resolution timing mode
provides double the normal 500 MHz sample rate on one-half of the channels.
By trading half of the analyzers channels, the remaining channels can be sampled
at a 1 GHz rate with double the memory depth. 4X high resolution timing mode
provides quadruple the normal 500 MHz sample rate on one-fourth of the
channels. By trading three-fourths of the analyzer’s channels, the remaining
channels can be sampled at 2 GHz with quadruple the memory depth.
P6419 Logic Analyzer Probe Instructions
Reference
Both of the high resolution timing modes use the same demultiplexing channel
routing as shown in Tables 3 and 4. By taking care to assign critical signals to
the demultiplexing source channels, you can obtain extra timing resolution where
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
Signal Names
The above examples apply to a 136-channel logic analyzer module. The missing
channels in LA modules 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.
See Tables 5 through 8 for the P6419 probe and adapter signal connections.

Considerations
This section provides information on compression land footprint requirements
and physical attachment requirements.
The PCB holes, in general, do not have an impact upon the integrity of your
signals. Signal integrity impact is eliminated when the signals you route 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.
Land Footprint Requirements for P6419 Probes. See Figure 14 for the compression land footprint requirements for P6419 probes.

Special Considerations
WARNING. To avoid personal injury due to electric shock, always turn off the
power on your target system before cleaning the compression footprint.
H Cleanliness is important for a reliable connection. Refer to Cleaning the
P6419 Compression Footprints, located on page 8.
H Line boxes around the pin groupings are the via keepout areas (not part of
the actual land footprint).
H Solder mask is required between all land pads in the component keepout
area.
H Maintain PCB and solder mask tolerances for all signal runs in the keepout
areas to ensure that no exposed runs or metal exist between pads. This
prevents shorted signal runs.
H Solder mask hardness of at least 8H (pencil hardness) and thickness of at
least 0.0762 mm to 0.1270 mm (0.0003 to 0.0005 in) has been verified for
several hundred cycles without appreciable wear from the compression
contact cycling.
H The compression land footprint design was verified on the immersion gold
process.
Land Footprint Requirements for the Compression-on-PCB to P6434 Mictor
Adapter. See Figure 15 for the land footprint requirements for the Compression-
on-PCB to P6434 Mictor adapter. This compression adapter converts from the
new compression footprint to the existing P6434 Mictor-based 34-channel probe.
Refer to the P6434 Mass Termination Probe Manual for the Mictor land
footprint specification. Refer to Table 6 for the recommended channel mappings
for the Compression-on-PCB to P6434 Mictor adapter and Mictor-on-PCB to
Compression adapter.

Figure 15: Land footprint requirements for the Compression-on-PCB to P6434
Mictor adapter
Special Considerations
H Two compression land footprints must be spaced as per the mechanical
dimensions specified to support the compression adapter.
H Placement of the compression land footprints is only constrained with use of
the compression adapter, not in normal usage of the TLA7Nx/Px/Qx logic
analyzer module, the TLA600 series mainframes, or the TLA5000 series
mainframes with a high-density probe.
H The P6434 Probe and older logic analyzer modules do not support differen-
tial signals. Therefore, the compression adapter cannot be used to support
differential signals beyond capturing each side of the differential signal
independently in a single-ended manner. Note that the connection to the
CLK/QUAL signal is only connected to the positive side of the signal.
H The compression adapter will add capacitance to the P6434 probe input
capacitance. The Mictor adapter adds 2.7 pF to the high-density compression
probe load of 0.7 pF for a combined adapter capacitance load of 3.4 pF.
H The TLA7Lx/Mx/Nx/Px/Qx logic analyzer module, TLA600 series
mainframe, and TLA5000 series mainframe with a P6419 High-Density
Probe will connect directly to the compression land footprint to support high
performance data capture and viewing needs.
Physical Attachment Requirements for P6419 probes. The connector-less P6419
High-Density Probe interconnects are designed to accommodate PCB thickness
ranging from 1.27 mm to 6.35 mm (0.050 in to 0.250 in). To accommodate this
range, there are two versions of the design:
H Nut bar
H Press-in nut
P6419 Logic Analyzer Probe Instructions
33
Reference
If the PCB thickness is 1.27 mm to 2.36 mm (0.050 in to 0.093 in), use the nut
bar with the thin elastomer (see Figure 16).
If the PCB thickness is 2.36 mm to 6.35 mm (0.093 in to 0.250 in), use the
press-in nut with the thick elastomer (see Figure 17).

Special Considerations for the Nut Bar Design
H The nut bar backing plate is required to maintain PCB flatness, which
supports the compression connection.
H The nut bar snaps in and out of the PCB without the use of tools.
H Nut bars are reusable and are not required to be a permanent part of the PCB.
H The elastomer is independent and replaceable.
H Additional nut bars and both thick and thin elastomer holders may be
ordered from Tektronix.

and Mictor-on-PCB to Compression Adapters. See Figure 3 on page 3 for the
mechanical dimensions of the adapters.
This section provides information on transmission lines and load models for the
P6419 High-Density Probes.
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 50 Ω
terminations on the line). 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
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.

Maintenance
Probe Calibration
Functional Check
The P6419 probe does not require scheduled or periodic maintenance. Use the
procedures listed under Functional Check to check the basic functionality of the
probe.
To confirm that the probes meet or exceed the performance requirements for
published specifications with a compatible TLA7Lx/Mx/Nx/Px/Qx module,
TLA6xx logic analyzer or TLA520x logic analyzer, refer to the Performance
Verification Procedures in the appropriate logic analyzer service manual.
If performing the probe calibration yourself, refer to the appropriate logic
analyzer service manual for the complete calibration procedure. Otherwise,
return the probe to the local Tektronix service center.
NOTE. For the default setup, if you connect probes to any channels other that the
A2 or A3 groups, you must define the groups and channels in the Setup window
before acquiring data on other probe channels.
Connect the logic analyzer probes to a signal source, start an acquisition, and
verify that the acquired data is displayed in either the Listing or Waveform
windows.
If available, use the TLACAL1 fixture to run the performance verification. For
further details, refer to the performance verification procedure in the appropriate
logic analyzer service manual.
Inspection and Cleaning
CAUTION. To prevent damage during the probe connection process, do not touch
the exposed edge of the elastomer.
To maintain a reliable electrical contact, keep the probes free of dirt, dust, and
contaminants. Remove dirt and dust with a soft brush. For more extensive
cleaning, use only a damp cloth. Never use abrasive cleaners or organic solvents.
