Performance Veri

cation
This section contains procedures to verify that the instrument performs as
warranted. Verify instrument performance whenever the accuracy or function of
your instrument is in question.
Tests Performed
Do the following tests to verify the performance of the TLA5000 Series logic
analyzers. (See Table 24.) You will need test equipment to complete the
performance veri
fi
cation procedures. (See Table 22 on page 22.) If you substitute
equipment, always choose instruments that meet or exceed the minimum
requirements speci
fi
ed.
Also note that setup procedures for your equipment may differ from those
described in the procedures, due to changes in the equipment or
fi
rmware. For
example, output connectors might be BNC or SMA, and setup menus can differ
between models.
