Performance Verification Procedures
This section contains procedures to verify that the TLA721 Benchtop Mainframe
and the TLA7XM Expansion Mainframe perform as warranted. Verify instru-
ment performance whenever the accuracy or function of your instrument is in
question.
Do the following tests listed in Table 4--3 to verify the performance of the
TLA721 Benchtop Mainframe and the TLA7XM Expansion Mainframe. You
will need some of the equipment shown in Table 4--1 on page 4--3 to complete
the performance verification procedures. If you substitute equipment, always
choose instruments that meet or exceed the minimum requirements specified.
