All system trigger and external signal input latencies are measured from a falling-edge transition (active true low) with
signals measured in the wired-OR configuration.

2

In the Waveform window, triggers are always marked immediately except when delayed to the first sample. In the Listing
window, triggers are always marked on the next sample period following their occurrence.

3

“Clk” represents the time to the next master clock at the destination logic analyzer. In the asynchronous (or internal)
clock mode, this represents the delta time to the next sample clock beyond the minimum asynchronous rate of 4 ns. In
the synchronous (or external) clock mode, this represents the tim e to the next master clock generated by the setup of the
clocking state machine and the supplied system under test clocks and qualification data.

4

Signals 1 and 2 (ECLTRG0, 1) are limited to a “broadcast” mode of operation, where only one source is allowed to drive
the signal node at any one time. That single source may be utilized to drive any combination of destinations.

5

SMPL represents the time from the event at the probe tip inputs to the next valid data sample. In the Normal Internal clock
mode, this represents the delta time to the next sample clock. In the MagniVu Internal clock mode, this represents 500 ps
or less. In the External clock mode, this represents the time to the next master clock generated by the setup of the
clocking state machine, the system-under-test supplied clocks, and the qualification data.

Characteristic Description

Storage Control

Global storage Storage is allowed only when a specific condition is met. This condition can use any

of the trigger machi ne resources except for the counter/timers. Storage commands
defined in the current trigger state will override the global storage control.

Global storage can be used to start the acquisition with storage initially turned on
(default) or turned off.

By event Storage can be turned on or off; only the current sample can be stored. The event

storage control overrides any global storage commands.

Block storage When enabled, 31 samples are stored before and after the valid sample.

Not allowed when glitch storage or setup and hold violation is enabled.

Glitch violation storage The acquisition memory can be enabled to store glitch violation information with each

data sample when asynchronous clocking is used. The probe data storage size is
reduced by one half (the other half holds the violation information). The f astest
asynchronous clocking rate is reduced to 10 ns.

Setup and hold violation storage The acquisition memory can be enabled to store setup and hold violation information

with each data sample when synchronous clocking is used. The probe data storage
size is reduced by one half (the other half holds the violation information). The
maximum clock rate is reduced by half.

Each use of External Signal In, glitch detector, setup and hold violation detector, or transition detector requires a trade-off
of one word recognizer resource.

TLA600 Series Logic Analyzer Service Manual

Theory of Operation

This section provides a brief overview of the board level theory of operation for
the logic analyzer. Refer to page 9--1 for a functional block diagrams.

Hardware

The logic analyzer contains the following major components:

Controller Board

Riser Board

Interface Board

An NLX mother board based on an Intel Celeron microprocessor and the 810E
chip set runs the operating system software in the TLA600 series logic analyzers.
This controller provides the hardware connections to the following devices:

H USB port

H PS2 mouse and keyboard

H Serial port

H Parallel port

H SVGA port

The NLX mother board receives power through a riser board connected to the
interface board. The mother board communicates with the interface board
through the PCI bus and the USB bus.

The Riser board connects the NLX mother board to the interface board. It also
has the connections to the hard disk drive and to the CD-ROM drive.

The interface board contains the circuitry to interface the PCI bus to the VXI bus
to route the external signal and trigger I/O signals to generate the CLK10
reference. This generates the display signals for the internal display system (if
used).

IA Bus

Power Distribution (Rear)

TLA600 Series Logic Analyzer Service Manual

The IA bus allows communication with the instrument. This is a message-based
system that allows SCPI commands sent from the NLX/Interface controller to
the LPU circuitry on the acquisition board.

This board connects the power supply to the Interface board and to the acquisi­tion board.

3- 1

Theory of Operation

Power Distribution (Front)

Power Supply

Front Panel Keyboard

Display

Mechanical Chassis

This board is an additional connection between the power supply and the
acquisition board.

The power supply provides all voltages and currents to the logic analyzer. In
addition to the main power supply, the interface board generates the --2 V and

--5 V needed for proper operation.

This board contains the front panel keypad and five control knobs. The circuitry
is connected to the interface board through a USB bus.

The internal display is a 10.4-inch diagonal active matrix thin-film-transistor
(TFT) liquid crystal display with a built-in back light similar to the TLA700
Portable Mainframe. The back light can be dimmed to 60% of its value through a
custom Tektronix screen saver to extend its life and prevent the burning of the
screen. The color LCD is supported by an external DC switching regulator board
to provide the back light high voltage and a display adaptor board which
connects the interface board to the display.

The mechanical chassis provides the mechanical support structure for the
instrument, and includes the cooling system, the EMI shielding system, and all
the subsystems.

Probe Interface

The logic analyzer connects to the target system through the probe interface.
There is one connector per probe for a maximum of eight connectors depending
on the instrument configuration.

The logic analyzer can use the following probes to connect to the target system:

H P6417

H P6418

H P6434

Depending on the instrument configuration, you can connect up to eight P6417
or P6418 general purpose probes, or up to four P6434 high-density probes.

3- 2

TLA600 Series Logic Analyzer Service Manual

Acquisition

Theory of Operation

The acquisition board is mounted on the bottom of the instrument. It has several
custom CMOS ASCIs ,several full custom bipolar ICs, RAM for the acquisition
memory, and other miscellaneous circuitry. The acquisition board takes the data
acquired by the probes, determines when to clock the data into memory, and
communicates the acquisition information with the rest of the instrument.

The acquisition board also contains the LPU circuitry which interfaces between
the VXI bus and the acquisition circuitry.

No manual calibration or adjustments exist. All calibration is done by software
but requires the adjustment/verification fixture (671-3599-XX) to be used for
proper deskew. The calibration procedures are described in the Adjustment
Procedures chapter.

Performance Verification: Logic Analyzer

This chapter contains procedures for functional verification, certification, and
performance verification procedures for the TLA600 Series Logic Analyzers and
the adjustment/verification fixture. Generally, you should perform these
procedures once per year or following repairs that affect certification.

Summary Verification

Functional verification procedures verify the basic functionality of the instru­ment inputs, outputs, and basic instrument actions. These procedures include
power-on diagnostics, extended diagnostics, and manual check procedures.
These procedures can be used for incoming inspection purposes.

Certification procedures certify the accuracy of an instrument and provide a
traceability path to national standards. Calibration data reports are produced for
the logic analyzer modules as output from the performance verification and
adjustment software. In some cases, you will be required to manually fill out
certification data. For those cases, you can make copies of the calibration data
report included with this manual, and then fill out the reports with the data that
you obtain from the procedures.

Performance verification procedures confirm that a product meets or exceeds the
performance requirements for the published specifications documented in the
Specifications chapter of this manual. Refer to Figure 4--1 on page 4--2 for a
graphic overview of the procedures.

Adjustment procedures check for, and if necessary , correct any adjustment errors
discovered when performing functional or performance verification procedures.
The adjustment procedures for the logic analyzer modules are controlled by
software while the procedures for the adjustment/verification fixture require
manual intervention. Some of the adjustment procedures for the logic analyzer
modules also require manual intervention to move probes or change test
equipment settings.

The performance verification and adjustment software is provided on the product
CD-ROM. If you have not already done so, refer to Software Installation and
Removal beginning on page 2--6 for instructions on installing the performance
verification and adjustment software.

Certification

Use the performance verification procedures to check the accuracy of the system
clock and to perform the DC Threshold test. The instrument is certifiable if these
parameters meet specifications. Running the system clock test requires you to
record the test data on a copy of the Calibration Data Report (found at the end of
this chapter). You can print out a software-generated Calibration Data Record for
the DC Threshold test after running the performance verification and adjustment
software.

Other specifications can also be verified by running the complete performance
verification procedures.

Performance Verification Instructions

This section contains procedures to verify that the TLA600 series instruments
perform as warranted. V erify instrument performance whenever the accuracy or
function of your instrument is in question, or as part of an annual calibration/cer­tification. As a general rule, these tests only need to be done once a year.

Performance Verification: Logic Analyzer

Prerequisites

You will use the performance verification and adjustment software to complete
most of the performance verification procedures. You will check the accuracy of
the 10 MHz system clock manually without the software.

The performance verification and adjustment software contains instructions and
control programs for testing each characteristic designated as checked (n)inthe
Specifications chapter of this manual.

These procedures ask for the serial number of the instrument under test. Record
the serial number and state speed of the instrument (located on a label on the
right side of the back panel) so that you can enter the information when
prompted by the software.

The tests in this section comprise an extensive, valid confirmation of perfor­mance and functionality when the following requirements are met:

H The logic analyzer application must not be running.

H The performance verification and adjustment software must be loaded. Refer

to Software Installation and Removal on page 2--6.

H The logic analyzer must have been operating for at least 30 minutes at an

ambient temperature between +20_ C and +30_ C.

H The logic analyzer must have been last adjusted at an ambient temperature

between +20_ C and +30_ C.

TLA600 Series Logic Analyzer Service Manual

Performance Verification: Logic Analyzer

H The logic analyzer must be in an operating environment within the limits

described in the Specifications chapter of this manual.

Procedure Overview

You will begin the procedures by performing the 10 MHz System Clock
(CLK10) test using manual checks and recording the results on copies of the
Calibration Data Report. You will then use the performance verification and
adjustment software to complete the remaining tests.

When using the performance verification and adjustment software, you will
connect external test equipment to the logic analyzer in response to prompts on
the screen. You will connect the test signals and then instruct the program to
continue. The performance verification and adjustment software automatically
selects the instrument settings and determines the results of each test.

The results of the tests are recorded in a temporary file and are available upon
test completion for completing test records for certification. To obtain partial test
information you can also run individual tests or selected groups.

NOTE. The self calibration (Self_Cal) test must run successfully before the other
tests are performed. The remaining tests can then be performed in any order.

Before testing an instrument following repair, you must first complete the
adjustment procedure.

The performance verification and adjustment software contains the tests shown
in Table 4--3. Each test verifies one or more parameters. All of the tests check
characteristics that are designated as checked (n)intheSpecifications chapter.
By running a full PV sequence, you will verify the performance of the logic
analyzer.

H RUN PARTIAL SEQUENCE runs part of the full sequence. The

sequence runs from the selected starting point to the end of the sequence.

Using the Interrupt Button

H SELECT TEST(S) runs only the selected tests. To run a single test, enter

the test number. To run multiple tests, enter a comma-separated list of
numbers or a hyphen-separated list of numbers.

Enter the number next to your choice and click Enter to continue.

14. Follow the on-screen instructions to connect and adjust test equipment.

15. When testing is completed, disconnect the test equipment.

While the program is running, you can interrupt the program to rerun a test, start
over, or to exit the program by clicking the Interrupt button (shown below).

The program will then provide a list of choices. Enter the number next to the
choice that you want and click Enter.

NOTE. If you interrupt a test before it has completed, you must restart the test to
obtain valid test data.

Obtaining Test Results

The results of all tests can be stored in a file on the hard disk. You can view the
test results, print the test results to a printer, or save the test results in another file
on the hard disk. The software stores the test results in a file containing the
module name and serial number (for example, TLA621.B020123). The file is
located under the following path: C:\Tekcats\Rpt.

NOTE. If you want to save the content of the Report file, you must rename or
copy the Report file using the Windows file utilities such as Explorer.

The Report file will be overwritten the next time you run the performance
verification and adjustment software and print or view a new set of test data.

After completing a full or partial test sequence (or just before you exit the
program) you can generate the test data and write it to a file. You have the option
of printing the file, viewing the file on screen, or transferring the file to another
directory or host computer.

You can print the test data directly from the program. Ensure that a printer is
connected to your logic analyzer and follow the on-screen instructions to print
the test results.

If a printer is not available, you can view the test results directly from the screen,
or you can copy the test results to a different file or folder/host computer for
future use.

Field Adjust/PV Software

Housekeeping

Troubleshooting

The performance verification and adjustment software creates data log files (.dlf
files) that store program data. The .dlf files are used by the performance
verification and adjustment software to generate the view data and print out
options. Each .dlf file is identified by the product serial number; for example,
B010100.dlf. The files are stored in the Tekcats folder under each TLA6xx
folder. To conserve disk space, you must occasionally delete the .dlf files.

If any tests fail, use the following steps to troubleshoot the problems:

1. Check all test equipment for improper or loose connections.

2. Check that all test equipment is powered on and has the proper warm-up

time.

3. If you are using the adjustment/verification fixture, verify the LED is
lighted, the jumper positions match the on-screen instructions, and the
external connections are correct. (See Figure 4--4 for jumper locations.)

4. Rerun mainframe or module diagnostics and module adjustment.

5. Run the tests a second time to verify the failure.

TLA600 Adjustment Procedures

This chapter contains procedures which use the performance verification and
adjustment software to adjust the TLA600 Series Logic Analyzers to within
factory specifications. The performance verification and adjustment software
contains instructions and control programs for adjusting the logic analyzer. The
software describes test equipment connections and settings, selects setup
parameters, and loads calibration constants into memory.

This chapter also contains adjustment procedures for the adjustment/verification
fixture which begin on page 5--9.

These procedures adjust the logic analyzer for conformance with the warranted
characteristics listed in the Specifications chapter of this manual.

Adjustments should be done after repair or when any performance verification
tests have failed.

Prerequisites

These procedures ask for the serial number of the instrument under test. You can
access the serial number through the logic analyzer application. In the applica­tion, go to the System menu, select System Properties, and click on the LA tab.
However, you must quit the application before continuing with the performance
verification and adjustment software procedures.

Only trained service technicians should perform this procedure after meeting the
following requirements:

H The logic analyzer application must not be running.

H The performance verification and adjustment software must be loaded. Refer

to Software Installation and Removal beginning on page 2--6.

H The logic analyzer requires a 30-minute warm-up time in a +20_ Cto

+30_ C environment before it is adjusted. Adjustments performed before the
operating temperature has stabilized may cause errors in performance.

TLA600 Adjustment Procedures

Using the Software

This section describes how to perform adjustments using the performance
verification and adjustment software.

Performing the

Adjustments

Adjustment Sequences

and Dependencies

Adjustment After Repair

There are no manual adjustments for the logic analyzer. Instead, the performance
verification and adjustment software adjusts the instrument hardware using
external test equipment connections that you provide in response to prompts on
the screen.

Upon successful completion of each adjustment, the performance verification
and adjustment software automatically loads the new calibration data into
memory.

The performance verification and adjustment software allows you to run groups
of adjustments, or sequences. A sequence consists of one or more individual
adjustments. Normally you will perform a RUN FULL SEQUENCE, which
executes each adjustment in the proper order.

The performance verification and adjustment software also provides instructions
for running each adjustment individually. However, you should only perform
individual adjustments while troubleshooting.

You must perform a full adjustment sequence following replacement of any
circuit board.

Test Equipment

5- 2

In addition to the basic system setup, you will need some of the equipment
shown in Table 4--1 on page 4--3 in the Performance Verification chapter.

Each procedure includes a table that calls out the equipment used. Use Table 4--1
to identify required equipment specifications. If you substitute equipment,
always choose instruments that meet or exceed the minimum requirements
specified.

8. After completing all the adjustment steps, view the results to confirm that

the adjustment was successful.

Troubleshooting

Tests Performed

If any adjustments fail, use the following steps to troubleshoot the problems:

H Check all test equipment for improper or loose connections.

H Check that all test equipment is powered on and has the proper warm-up

time.

H Verify that the adjustment/verification fixture LED is lighted, the jumper

positions match the on-screen instructions, and the external connections are
correct.

H Rerun the diagnostics and self calibration (SELF_CAL).

H Run the adjustment procedures a second time to verify the failure.

The adjustment procedures check and adjust the following parameters of the
logic analyzer:

H SELF_CAL, an internal routine in the application software that adjusts

acquisition thresholds, internal module and signal timing.

H Deskew, an adjustment routine in the performance verification and adjust-

ment software which time-aligns all channels.

Adjustment Procedures

Self Calibration

TLA600 Adjustment Procedures

Refer to the following procedures to identify the initial setup for each adjust­ment. Then follow the program instructions to complete the adjustments.

SELF_CAL is an internal routine that optimizes performance at the current
ambient temperature to maximize measurement accuracy. No external equipment
or user actions are needed to complete the procedure. The logic analyzer saves
data generated by the self calibration in memory. Passing the self calibration
provides a higher level of confidence of functionality.

NOTE. Performing the self calibration does not guarantee that all parameters
operate within limits. Operation within limits is achieved by performing the
adjustment procedures. Verification of operation within limits is accomplished by
performing the performance verification procedures.

TLA600 Procedure 1:

SELF_CAL

When to Perform the Self Calibration. You can run the self calibration at any time
during normal operation. To maintain measurement accuracy, perform the
self calibration if the following conditions occur:

H After repair and replacement of any circuit boards

H It has been a year since the last self calibration was run

Perform the following steps to run the SELF_CAL routine. Before beginning
this procedure, be sure that no active signals are applied to the instrument. Self
calibration can fail if signals are applied to the probe during the procedure.

Prerequisites Warm-up time: 30 minutes

Power-up diagnostics pass

1. Ensure that the logic analyzer has had a 30-minute warm up before attempt­ing the self calibration, and that the logic analyzer application is running.

2. Disconnect any probes connected to the logic analyzer.

3. Select the Calibration and Diagnostics property sheet from the System menu.

4. Select the Self Calibration tab.

TLA600 Series Logic Analyzer Service Manual

5- 5

TLA600 Adjustment Procedures

5. Click the Run button to start the self calibration.

The self calibration takes several minutes to complete, depending on the
number of channels in the instrument. Upon successfully completing the self
calibration, the status changes from Running to Calibrated, and the Date and
Time field is set to the present.

TLA600 Procedure 2:

Deskew

The deskew procedure is used to calibrate and adjust the timing alignment of the
probe data channels and receivers.

Perform the deskew procedure:

H Once a year

H If you have replaced the acquisition board (the probe constants are stored on

the acquisition board)

This procedure checks and adjusts the time alignment of all channels. There are
no manual adjustments.
