Performance Verification
TLA5000 Series Service Manual
4- 9
There are two ways of verifying probe functionality. One way is to connect the
probes from the logic analyzer to a signal source, adjust the appropriate threshold
voltage levels, and then verify that the logic analyzer acquires the data in a
listing or waveform window.
Alternately, you can perform the performance verification procedures which will
verify that the logic analyzer and the attached probes meet or exceed the
advertised specifications. The performance verification procedures are covered in
the remainder of this chapter.
Performance Verification Instructions
This section contains information to verify the performance of the logic analyzer.
Testing is performed using the performance verification software and the test
fixture.
As a general rule, these tests should be done once a year.
The performance verification procedures in this section comprise an extensive,
valid confirmation of performance and functionality when the following
requirements are met:
H
The performance verification software must be loaded on the hard disk.
H
The logic analyzer, test fixture, and other related test equipment must be
installed, connected, and operating for at least 30 minutes at an ambient
temperature b20
_
C and +30
_
C.
H
The logic analyzer and the test fixture must have been last adjusted at an
ambient temperature b20
_
C and +30
_
C.
H
The logic analyzer and test fixture must be in an operating environment
within the limits described in the
Tektronix Logic Analyzer Product
Specifications document.
When using the performance verification software, you will connect external test
equipment and probes to the logic analyzer in response to prompts on the screen.
The 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.
