Getting Started
The probe adapter (preprocessor unit and probe head) is an interposer design that allows the logic analyzer to acqui re data
from a microprocessor in the operating environment with little effect on the DUT.
To accomplish this, the probe adapter is connected to the DUT, and then the microprocessor is connected to the probe
head. Signals from the microprocessor-based system flow through the probe cables to the logic analyzer.
The TMSST2 product includes:
H CD-ROM with PUB32G11 software and manual
H TMSST2 preprocessor unit
NOTE. To acquire signals from the DUT, you need compatible cables, probes, and probe head to complete the connection
between the logic analyzer and the DUT. Contact your Tektronix sales representative for information about these other
products.
For optional and standard accessories for this product, see Accessories on page 16.
Getting Started
For a list of replaceable parts, see page 13.
Logic Analyzer Configuration
To use the preprocessor unit and probe head to acquire most signals, you need a Tektronix logic analyzer with four merged
TLA7AX4,
All signals are acquired through a combination of P6860 probes and TMSCAB1 cables connected to the logic analyzer.
The P6860 probes should already be labeled; if you need to apply labels, refer to the instructions that came with your
probe documentation.
Refer to the P6810, P6860, and P6880 Logic Analyzer Probes Instruction manual, Tektronix part number 071-1059-xx, for
more information about the P6860. Access the latest version of the manual from the Tektronix.com Web site.
Master and Slave Module Configuration
The modules must be configured and
merged as shown.
H The memory depth is automatically
based on the shallowest memory depth of
the modules.
H The term Master module refers to the
second module of a 4-wide module
configuration. The term Slave module
refers to the modules to the left or right of
the Master module.

Configure the Preprocessor Unit
Getting Started
To acquire the necessary signals from the DUT, the preprocessor unit generates two tracking voltages referred to as V
and V
REF.VTERM
is the voltage to which most of the received target signals are terminated, while V
is the reference to
REF
TERM
which the attenuated target signals are compared.
You can configure the preprocessor unit to use one or more of the GTLREF signals and combine these signals with an
offset voltage using the jumpers on top of the preprocessor unit. (See Figure 1.)
Review the schematic diagram in Figure 1 to understand how the jumpers and offset adjustments define the reference and
termination signals. The connectors provide access for monitoring the voltages.

Getting Started
Select a GTLREF Signal
The most common and straightforward scenario is to select an individual GTLREF signal using the jumpers to generate a
reference and termination voltage. When you enable a GTLREF signal, the average voltage is equal to the GTLREF
voltage.
As an alternative to a single GTLREF selection, you can combine two or more GTLREF signals that result in the average
of all the contributors. The next step beyond a GTLREF only selection is to add a DC offset. The resultant voltage
continues to track GTLREF. Refer to the following combined calculation:
or V
V
REF
TERM
= ((V
OFFSET
-- V
GTLREF_AVG
) x 0.130) + V
GTLREF_AVG
If you choose only the offset voltage to define the termination or reference voltage, a weighting factor is not used and the
full magnitude offset voltage defines the resultant voltage.
For example, you selected a GTLREF signal that equals 0.7 V, the AVERAGE GTLREF jumper is enabled, and you are
using an offset voltage to provide +0.05 V of offset. The resultant voltage would be 0.75 V.
To set this offset voltage, adjust to:
V
OFFSET
=7.69(V
RESULT
-- V
GTLREF_AVG
)+V
GTLREF_AVG
= 7.69 (0.75--0.70) + 0.70
= 1.0845 V
To summarize, the offset voltage source must be at 1.08 V to provide the +0.05 V of offset (in combination with an
averaged GTLREF signal equal to 0.7 V). Therefore, if the AVERAGE GTLREF jumper is moved to the disabled position,
an offset only selection sets the resultant voltage at 1.08 V.
NOTE. All jumpers and connectors are located on top of the preprocessor unit.

When you enable both the AVERAGE GTLREF and the OFFSET jumpers, the resultant terminat ion and reference
voltages are weighted (20 to 3) to provide a substantial degree of GTLREF tracking.
Even when the AVERAGE GTLREF jumper is disabled for both the reference and termination voltage, the average
GTLREF signal is used to generate a reference voltage for 13 target signals. To guarantee that the average GTLREF
signal is at an appropriate level, the average GTLREF signal defaults to the processor land H1 on the DUT, if all five
jumpers are placed in the disabled position.

NOTE. If the land H1 on the DUT is the desired GTLREF signal, use the jumper on the preprocessor unit to enable it
rather than relying on defaults. The land H1 default is only intended to prevent undefined conditions from occurring.
Adjust GTLREF Offset Voltage
To use either reference or termination offset voltage, you must enable it . (See Table 2 on page 5.) Connect a voltmeter to
the Reference or Terminator connector and GND on the preprocessor uni t using standard cables. The voltage is the
averaged signal that is used by the front-end comparators (reference average and termination average). If the manual USE
OFFSET jumper is the only jumper enabled, the voltage at the connector directly reflects the manual offset volt age.
CAUTION.
Connecting a voltage source to the Reference or Terminator connectors can damage the
preprocessor unit. Only use standard cables to read the manual offset voltage. (See Table 3.)

Adjust the offset voltage with a small screwdriver, if necessary. (See Table 4.) Turn the potentiometer clockwise to increase

Circuit Description
The preprocessor unit and probe head processes all signals on the microprocessor before the logic analyzer captures the
signals. The TMSST2 product performs the following functions:
H Latches signals within a narrow valid window
H Demultiplexes quad-pumped, source-synchronous signals
H Deterministically synchronizes source-synchronous data signals to BCLK
Latched Operation
The signals are processed according to their type. Following is a description of each type:
4x Quad-Pumped Signals. These si gnals include D[63:00]# and DBI[3:0]#. The signals are latched usi ng dedicated
strobes, STBP[3:0] and STBN[3:0], and then four-way demultiplexing is performed on these signals. The LAI inverts the
appropriate signals when the DBI[3:0] signals are active.
Reference
2x Double-Pumped Signals. These signals include A[39:03]# and REQ[4:0]#. The LAI buffers and restores these signals.
It then sends the signals to the logic analyzer along with ADSTB[0] to be multiplexed into the common clock domain. The
logic analyzer uses the ADS to deterministically place these signals into the correct clock frame.
1x Common-Clock Signals. These signals include all of the remaining front side bus signals. The logic analyzer latches
these signals using the rising edge of BCLK.
Signal Probing
The probe head uses passive series isolation to acquire data.
GTLREF Jumper Settings
The preprocessor unit uses reference voltages from the target system to derive a signal called GTLREF_AVG. This voltage
is used as a reference to acquire most signals from the target system. The preprocessor unit can average up to five
reference voltages and a manual offset voltage. See Configure the Preprocessor Unit beginning on page 3.

TMSCAB1 Labels
If you need to attach labels to the module end and the preprocessor end of theTMSCAB1 cables, use the following
instructions.
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 the label to the indented outline on the module end
and preprocessor unit end. Once labels are placed on the TMSCAB1 cabl es, they are difficult to remove.
Follow these steps to attach the labels:
1. Determine which channel groups you
plan to use and identify the matching labels.
2. Align and place the label in the label indent (preprocessor-unit end).
Reference

Probe Adapter Notes
Probe Adapter Notes
Review electrical, environmental, and mechanical specifications in the Specifications section starting on page 23 because
they pertain to the target system, and to the following information.
Acquisition before Reset. If data is acquired before a processor Reset signal is observed by the preprocessor unit, the
data acquired by the logic analyzer will be inaccurate.
Data Bus. The TMSST2 product supports only a quad-pumped data bus.
Address Bus. The TMSST2 product supports only a double-pumped address bus.
Disabling the Cache (disassembly). The cache bus is not observable; therefore, disassembly requires that the cache
must be disabled. Disabling the cache makes all instruction prefetches visible on the bus so that they are acquired,
displayed, and correctly disassembled.

Specifications
These specifications are for a probe adapter (preprocessor unit and probe head) that is connected between a compatible
Tektronix logic analyzer and a target system. All specifications are typical. This section also outlines the electrical and
mechanical requirements that the system-design engineer must observe during the planning and designing of their target
system. This planning ensures compatibility with the probe adapter.
NOTE. These specifications can be used with the TMSSPH1 probe head with the exception of the dimensional drawing, or
noted otherwise.
Reference Voltage
Some target systems incorporate multiple reference voltages. These voltages are averaged by the preprocessor unit and
used to receive all signals. Figure 2 shows an example of averaging two different reference voltages.
Specifications
Composite probe
adapter time/voltage
V
REF1
V
REF2
Figure 2: Multiple reference voltage averaging
NOTE. The overall time/voltage eye seen by the probe adapter is reduced when different reference voltages are present in
the target system.
When designing a multiple reference voltage system, the system designer must ensure that the composite eye seen by the
preprocessor unit conforms to the electrical requirements described in this section. All electrical requirements listed in this
section are relative to the averaged reference voltage.
The preprocessor unit provides a user-defined offset that can be added to the averaged reference vol tage for flexibility. The
offset function can also be used by itself, and adjusted to a desired fixed voltage. The averaged reference voltage tracks
changes in the references, while the offset is a fixed vol tage. To provide a significant amount of tracking while using an
offset, the averaged reference is weighted 20:3 relative to the Offset voltage.
The TMSST2 preprocessor unit generates a separate termination and reference voltage.
With separate reference and termination voltages, it is possible to adjust the termination voltage to optimize target-system
performance with the preprocessor unit installed and active. You can then adjust the reference voltage to optimize the
preprocessor unit operation and achieve error-free acquisition. In most applications, the affect of the probe adapter loading
is low enough to suffice for the simplest case of reference and termination voltages (both being set to the averaged
reference only, no offset). Independent adjustments with or without offsets are available, if needed.

substantial noise immunity but requiring a substantial overdrive.

For both the DSTB and ADSTB signal groups, the voltage domain hysteresis is adjustable at the factory from 3.5 mV
typical to over 100 mV at the probe tip. The amount of hysteresis applied cannot be changed. The amount of hysteresis is
set to nominally 48 mV (ᐔ24 mV).
The time domain hysteresis is different for the DSTB and ADSTB groups. For the DSTB group, any nonmonotonic
anomaly within 0.8 ns of an incident falling-edge is ignored. For the ADSTB group, any nonmonotonic anomaly within 1250
ps of the incident falling or rising edge is ignored.

Descriptions
Pollution Degree
Class 1 -- grounded product
A measure of the contaminates that could occur in the environment around and within a product.
Typically the internal environment inside a product is considered to be the same as the external.
Products should be used only in the environment for which they are rated.
H Pollution Degree 1. No pollution or only dry, nonconductive pollution occurs. Products in this
category are generally encapsulated, hermetically sealed, or located in clean rooms.
H Pollution Degree 2. Normally only dry, nonconductive pollution occurs. Occasionally a
temporary conductivity that is caused by condensation must be expected. This location is a
typical office/home environment. Temporary condensation occurs only when the product is
out of service.
H Pollution Degree 3. Conductive pollution, or dry, nonconductive pollution that becomes
conductive due to condensation. These are sheltered locations where neither temperature
nor humidity is controlled. The area is protected from direct sunshine, rain, or direct wind.
H Pollution Degree 4. Pollution that generates persistent conductivity through conductive dust,
rain, or snow. Typical outdoor locations.
Pollution Degree 2 (as defined in IEC 61010-1). Note: Rated for indoor use only.
