Product Description

This section provides a brief description of the Tektronix P68xx Logic Analyzer
Probes and adapters, information on attaching color-coded probe labels, and
probe and adapter connection instructions from the logic analyzer to the target
system.

The P68xx Logic Analyzer Probes connect a TLA7Axx Series Logic Analyzer
module to a target system. The P6810, P6860 and P6880 probes consists of
34 channels, while the P6864 probe consists of 17 channels. You can connect the
P6810 probe to the target system through podlet holders or leadsets. In addition,
a variety of leadsets, SMT KlipChips and adapters aid in your connection to the
target system. The P6860 probe can be connected through the use of the
compression land pattern or a Mictor connector using the Mictor-on-PCB to
P6434 to Compression adapter. The P6880 probe is designed for connection to
the compression land pattern only configured for differential signals. The P6880
is not compatible with either the Mictor-on-PCB to P6860 probe adapter or the
Compression-on-PCB to P6434 probe adapter. The P6864 probe can be
connected through the use of the compression land pattern. Note that the P6864
is designed to minimize the needed area on the circuit board for connections
when using the 4X clocking mode in the logic analyzer module.

P6810 Leadset Adapters

and Accessories

Leadsets enhance flexible access to the target system signals by allowing
single-pin podlet connections of signals and grounds. This allows the separation
of ground and signal connections, providing flexible access to the PCB and
backplane connections where signals are not easily accessible together. The
following leadsets and accessories accompany the P6810 General Purpose Probe.

H 1-Channel single-ended and differential leadset. Supports individual

leadset connections to backplanes and other connection points requiring

single-ended 2 mm (0.079 in) and 2.54 mm (0.1 in) connections. Both leads

contain 150 Ω damping resistors in the lead tips.

H 8-Channel single-ended leadset. Supports individual leadset connections to

backplanes and other multiple, dense, single-end connections in a 2 mm

(0.079 in) and/or 2.54 mm (0.1 in) pin array. Two common ground connec-

tions for all input signals. The positive leads contain 150 Ω damping

resistors and the leadset housing contains a 150 Ω damping resistor in the

ground path of each channel.

H 8-Channel differential leadset. Supports individual leadset connections to

backplanes and other multiple, dense, differential connections in a 2 mm

(0.079 in) and/or 2.54 mm (0.1 in) pin array. Individual + and -- leads for

each differential signal input. All leads contain 150 Ω damping resistors in

the lead tips.

Mictor-on-PCB to P6860

Compression Adapter

The Mictor-on-PCB to P6860 Compression adapter (see Figure 1--6) allows
existing microprocessor support packages and your hardware designs with
embedded Mictor connectors to be connected to the P6860 High-Density Probe.

The CLK pin on the Mictor is connected to the CLK+ pin of the compression
footprint. The CLK-- pin of the compression footprint is tied to ground. This
allows the differential clock input of the P6860 probe to function as a
single-ended signal.

This adapter supports standard Mictor connector footprints and signal connec­tions on older logic analyzer designs.

Differential qualification and clock signals are not supported through the
Mictor-on-PCB to Compression adapter due to Mictor footprint limitations (only
+ side of clock and qual signals are supported).

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.

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. R outing
the appropriate signals from our design to these inputs ensures that the logic
analyzer can acquire data correctly. Unused clocks can be used as qualifier
signals.

P68XX Series Logic Analyzer Probes Instruction Manual

2- 1

Reference

TLA7Axx

Depending on the channel width, each TLA7Axx Series logic analyzer module
will have different set of clock and qualifier channels. Table 2--1 shows the clock
and qualifier channels available for each module.

All clock and qualifier channels are stored. The analyzer always stores the logic
state of these channels every time it latches data.

Since clock and qualifier channels are stored in the analyzer memory 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 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 analyzer clock inputs will provide you with a 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 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 busses (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

2- 2

P68XX Series Logic Analyzer Probes Instruction Manual

Reference

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.

Merged Module Sets and Source Synchronous Clocking. TLA7Axx analyzer
modules that are 102 channels or 136 channels wide can be merged together to
act as a single logic analyzer with a larger channel count. Up to five modules can
be merged to provide up to a 680 channel analyzer. A unique feature of the
TLA7Axx module is that it supports source synchronous clocking. Combining
these two capabilities provide some additional considerations for signal routing.

Source synchronous clocking is a method which manages the skew between the
system clock and the data bus by requiring the sending device to drive an actual
clock or strobe signal along with the data that is very tightly coupled with it in
terms of skew. The receiving device then uses this strobe to capture the data.

A variant of this scheme is being applied to large microprocessor busses, where
the bus is split into smaller, more easily managed groups that each have their
own dedicated strobe. Although the timing relationship between a particular
clock and its associated data group is very tight, the timing between the different
groups can vary greatly and changes depending on which device has control of
the bus.

Many source synchronous designs use wide busses. It is not uncommon to
require a set of merged logic analyzer modules to provide the channel count
needed in probing larger source synchronous systems. While all of the modules
in a merged set can use their clock inputs independently if needed, it must be
remembered that there are a maximum of four clock inputs on a 136 channel
wide module.

To see the importance of this reminder we will once again use a microprocessor
system as an example. Tektronix logic analyzer processor has a 32 bit address
bus and a 64 bit data bus. The data bus is split into four 16 bit subgroups that
have independent source synchronous clocks. For the logic analyzer to correctly
acquire data from this system it will need five clock inputs, one for the address
bus and one each for the four 16 bit data bus subgroups.

To acquire both busses the analyzer would need at least 96 channels (32 address
and 64 data). However, a single 102 channel card doesn’t have the required five
clock inputs. By merging two 102 channel modules into a set you can obtain the
needed number of clock inputs. Route the address bus to one module in the set
and route the data bus, along with its four source synchronous clocks, to the
second module in the set.

Demultiplexing Multiplexed Busses. TLA7Axx module supports both 2X and 4X
demultiplexing. Each signal on a dual or quad multiplexed bus can be demulti­plexed into its own logic analyzer channel. See Tables 2--2 and 2--3 to determine

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. Tables 2--2 and 2--3 show 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.

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 analyzers channels the remaining
channels can be sampled at a 2 GHz rate with quadruple the memory depth.

Reference

Both of the high resolution timing modes use the same demultiplexing channel
routingasshowninTables2--2and2--3.Bytakingcaretoassigncriticalsignals
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.

Probing Analog Signals. TLA7Axx module provides visibility of analog signals
with iView. iView routes the actual signal seen by each channel’s probe through
a high bandwidth path to an analog multiplexer inside of the logic analyzer
module. From the logic analyzer interface you can route any input channel to one
of four output connectors on the module. By connecting the analyzer iView
analog probe outputs to your oscilloscope you can see the analog characteristics
of any signal probed by the logic analyzer.

Sometimes there are analog signals that would be convenient to have fixtured for
easier probing. Signals such as A/D Converter inputs, D/A C onverter outputs,
low voltage power supplies, termination voltages, and oscillator outputs are just
a few examples. Routing these signals to unused logic analyzer inputs provides a
quick method of viewing their activity without ever picking up a scope probe.

Signal Names

Care must be taken to ensure that such signals are voltage limited and will not
exceed the maximum nondestructive input voltage for the logic analyzer probes
of ±15 Vpeak.

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 LA 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 2--4 through 2--14 for the P6810, P6860, P6864, and P6880 Probes
and adapters signal connections. Match the alpha character that precedes the
channel identifier (for example, E3:7) to the probe head label. This will simplify
probe connections to the logic analyzer when you use the following tables.

Special Considerations for the Adapters. The following are issues to consider
when you use either the Compression-on-PCB to P6434 Mictor adapter or the
Mictor-on--PCB to P6860 Compression adapters.

H Use of the Compression-on-PCB to P6434 Mictor and Mictor-on-PCB to

P6860 Compression adapters on existing 68 and 34 channel embedded
configurations and supports may require exchanging the P6860 Probe heads
or P6434 module connector ends to accommodate all older Tektronix logic
analyzer signal connection alternatives. For additional information on P6434
and P68xx probe-to-module orientation refer to the following:

H P6810 General Purpose Logic Analyzer Probe Label Instructions

tions

H P6864 High Density 4X Logic Analyzer Probe Label Instructions

H P6434 Probe Label Instructions

Land Footprints

H On the Compression-on-PCB to P6434 Mictor adapter, the negative side of

the differential clock/quals are left floating (N/C) to allow a differential clock
signal to be connected to the compression footprint and still be probed by a
P6434. However, the P6434 will only see the CLK+ side of the differential
line. This also allows the P6860 Probes to be connected in the future and
provide true differential clock/qual support.

H On the Mictor-on-PCB to P6860 Compression adapter, the negative side of

the differential clock/qual inputs on the compression connection side are
internally grounded to support viewing the single-ended clock/qual inputs
supported by the P6434 Probe and older Tektronix logic analyzers.

The following section shows the land footprints for the P6810, P686x, and
P6880 Probes. These figures contain the signal to land pattern assignments.

P6810 Probe Land Footprint. See Figure 2--1 for the P6810 General Purpose
Probe land footprint. Pin spacing allows for spacing tolerance between 8-channel
podlet holder and clock/qual podlet configurations. Negative inputs of differen­tial signals may be grounded to support single-ended signal inputs.

Figure 2- 6: High-Density Differential probe land footprint in a typical pass-through
signal path layout configuration

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 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.

Land Footprint Requirements for the P686x and P6880 Probes. See Figure 2--7 for
the compression land footprint requirements for the P686x and P6880 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

P686x and P6880 Compression Footprints, located on page 1--14.

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 All signal runs in the keepout areas are required to maintain PCB and solder

mask tolerances to ensure that no exposed runs or metal exist between pads.
This requirement avoids the risk of shorting 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 Figures 2--8 and 2--9 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 2--13 on page 2--16 for the recommended
channel mappings for the Compression-on-PCB to P6434 Mictor adapter and
Mictor-on-PCB to Compression 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 TLA7Axx logic analyzer
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.

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 TLA7Axx logic analyzer with the P6860 High-Density Probe will

connect directly to the compression land footprint to support high perfor­mance data capture and viewing needs.

H The TLA7Axx logic analyzer with the P6880 High-Density Differential

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 2--11).

If the PCB thickness is 2.36 mm to 3.81 mm (0.093 in to 0.150 in), use the
press-in nut with the thick elastomer (see Figure 2--12).

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 used is independent and replaceable.

H Additional nut bars and both thick and thin elastomer holders may be

ordered from Tektronix.

This section provides information on transmission lines and load models for the
P6810 General Purpose, P686x High-Density, and P6880 High-Density
Differential 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 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
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 and in the modeling.

Probe Calibration

Service Strategy

The P6810, P686x, and P6880 Probes do not require scheduled or periodic
maintenance. Refer to the Functional Check section (page 4--1) to verify the
basic functionality of the probes.

To confirm that the probes meet or exceed the performance requirements for
published specifications with a compatible logic analyzer module, refer to the
TLA7Axx Logic Analyzer Module Service Manual and follow the procedures
listed under performance verification procedures.

If performing the probe calibration yourself, refer to the TLA7Axx Logic
Analyzer Module Service Manual for the complete calibration procedure.
Otherwise, return the probe to the local Tektronix service center.

Except for the elastomer holders, the P6810, P686x, and P6880 Probes contain
no user-replaceable parts. If probe failure occurs, return the entire probe to your
Tektronix service representative for repair.

Functional Check

NOTE. For the default setup if you connect probes to any channels other than the
A2 and 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 TLACAL2 fixture to run the performance verification. For
further details, refer to the performance verification procedure in the TLA7Axx

Logic Analyzer Module Service Manual.
