Performance Verification: Logic Analyzer

TLA600 Series Logic Analyzer Service Manual
H
The logic analyzer must be in an operating environment within the limits
described in the
Specifications chapter of this manual.
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
) in the
Specifications
chapter
.
By running a full PV sequence, you will verify the performance of the logic
analyzer.
