Functional Verification Procedures
Functional verification procedures verify the basic functionality of the instrument inputs, outputs, and basic instrument actions. These procedures include
power-on and extended diagnostics, self calibration, as well as semi-automated
or manual check procedures. These procedures can be used for incoming
inspection purposes.
Certification Test Procedures
Certification procedures are used to certify the accuracy of an instrument and
provide a traceability path to national standards. Certification data is recorded on
Calibration Data Reports provided with this manual. Calibration Data Reports
are produced for the TLA600 Logic Analyzers, LA modules, and DSO modules
as an output from the PV/Adjust software.
Introduction
Performance V erification Procedures
Performance verification procedures confirm that a product meets or exceeds the
performance requirements for the published specifications documented in the
Tektronix Logic Analyzer Family User Manual. Refer to Figure 1–1 on
page 1–4 for a graphic overview of the procedures.
Adjustment Procedures
Adjustment procedures check for and, if necessary, correct any adjustment errors
discovered when performing functional or performance verification procedures.
The adjustment procedures documented in this manual are controlled by
software, except for the procedures for the adjustment/verification fixture.
Some procedures require user intervention to move probes or change test
equipment settings. The adjustment software is part of the self-calibration
routines in the logic analyzer application software and the PV/Adjust software
provided with the product CD-ROM.

If the test you are attempting to run fails, do the following:
HCheck the settings and connections of the test equipment used in the
procedure.
HIf you are using the adjustment/verification fixture, verify that the LED is
lighted and that the jumper positions and external connections are correct.
HRerun mainframe or module diagnostics and module self-cal, then rerun the
test(s) which failed.
If the test(s) still do not pass, the mainframe or module might need further
troubleshooting.
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

Introduction
NOTE. If you interrupt a test before it has completed, you must restart the test to
obtain valid test data.
Some tests such as Internal Cal do not allow interrupts. If you stop these tests
using more aggressive methods, you may have to reboot the instrument.
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.
After running the performance verification procedures, you should create a
calibration data report for certification purposes. Refer to Calibration DataReports for details on using the resultant test data with the Calibration Data
Report.
Calibration Data Reports
The Calibration Data Reports in this manual are intended to be copied and used
for calibration/certification procedures. Some of the certification procedures
require you to record data from manual measurements on the Calibration Data
Reports directly. The TLA600 Logic Analyzer, the LA module, and the DSO
module procedures require that you obtain the test results from the file created by
the PV/Adjust software.
After completing the performance verification procedures or the certification
procedures, you can fill out a Calibration Data Report to keep on file with your
instrument. Calibration Data Reports are provided at the end of the certification
procedures in each chapter of this manual, except for the TLA600 Logic
Analyzer, the LA module, and DSO module. Calibration Data Reports for these
instruments are generated by the PV/Adjust software. The Calibration Data
Reports list those product attributes and specifications upon which product
accuracy depends.
Retrieving Test Data from
the PV/Adjust Software
1–14
The program stores the test results in a file containing the module name and
serial number (for example, TLA7E2.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 PV/Adjust software
and print or view a new set of test data.
Tektronix Logic Analyzer Family Performance Verification and Adjustment Procedures
Introduction
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
The PV/Adjust software creates data log files (.dlf files) that store program data.
The .dlf files are used by the PV/Adjust software to generate the view data and
print out options. Each .dlf file is identified by the product serial number;
example, B010100.dlf. The files are stored in the Tekcats folder under each
TLA7xx folder. To conserve disk space, you must occasionally delete the .dlf
files.

HCheck that all test equipment is powered on and has the proper warm-up
time.
HVerify that the adjustment/verification fixture LED is lighted, the jumper
positions match the on-screen instructions, and the external connections are
correct.
HRerun the diagnostics and self-cal.
HRun the adjustment procedures a second time to verify the failure.
HIf the adjustment procedures continue to fail, refer to the TLA 600 Series
Logic Analyzer Service Manual for corrective action.
The adjustment procedures check and adjust the following parameters of the
logic analyzer:
HSELF_CAL, an internal routine in the application software that adjusts
acquisition thresholds, internal module and signal timing.
Adjustment Procedures
2–26
Tektronix Logic Analyzer Family Performance Verification and Adjustment Procedures
HDeskew, an adjustment routine in the PV/Adjust software which time-aligns
all channels.
NOTE. Do not mix probe types (P6417, P6418 and P6434) when performing the
deskew procedure.
Refer to the following procedures to identify the initial setup for each adjustment. Then follow the program instructions to complete the adjustments.
Self Calibration
TLA600 Series Logic Analyzer Adjustment
Self calibration (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.
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:
TLA600 Procedure 1:
SELF_CAL
HAfter repair and replacement of any circuit boards.
HIt 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.
PrerequisitesWarm-up time: 30 minutes
Power-up diagnostics pass
1. Ensure that the logic analyzer has had a 30-minute warm up before attempt-
ing 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.
