Table 4--2 lists the specifications as checked (n)intheTektronix Logic Analyzer
Product Specifications document for the logic analyzer and the performance
verification software checks used to verify those specifications. In addition to the
software test listed in the table, some specifications are verified by the built-in
diagnostics. By running all tests and diagnostics, you will verify the performance
of the logic analyzer and probes.
Table 4- 2: Performance verification tests
