Performance Verification Tests Overview
Use the Performance Verification Tests to verify the
measurement performance of the instrument. The
performance verification tests use the instrument's
specifications listed in Chapter 6, “Specifications”.
You can perform four different levels of performance
verification tests:
Self- Test A series of internal verification tests that give a
high confidence that the instrument is operational.
Quick Verification A combination of the internal self- tests
and selected verification test.
Performance Verification Tests An extensive set of tests
that are recommended as an acceptance test when you first
receive the instrument or after performing adjustments.
Optional Verification Tests Tests not performed with every
calibration. Perform these tests to verify additional
specifications or functions of the instrument.
Self -Test
• A brief power- on self- test occurs automatically whenever
you turn on the instrument. This limited test assures that
the instrument is capable of operation.
• During the self- test all display segments and annunciators
are lit.
• If the self- test fails, an error is reported on the front
panel. You can also use the SYSTem: ERRor? command
query from the remote interface. If repair is required,
contact an Agilent Service Center.
• If all tests pass, you have a high confidence (~90%) that
the instrument is operational.
