Performance Verification Tests
The performance verification tests use the power supply’s specifications listed
in chapter 1, ‘‘Specifications’’, starting on page 13.
You can perform two different levels of performance verification tests:
•
Self-Test
A series of internal verifi cation tests that provide high
confidence that the power suppl y is operational .
•
Performance Verification Tests
These tests are used to verify that the
power supply is operating as specified in the performance specifications.
Self-Test
A
power-on
self-test occurs automat ically when you turn on the powe r supply.
This li m ited test assures you that th e power supply is operational .
The
complete
self-test is enabled by holding down key (actually any front
panel key s except key) as you turn on the power supply and
hold down
the key
until you hear a long beep
. The self-test will begin when you release
the key following the beep. The complete self-test takes approximately two
seconds to execute.
You can also perform a s elf-test from the remote interface (
see chapter 3 in
the Agile nt E3 633A and E3 634A Use r’s Guide
).
• If the self-test is successful, ‘‘PASS’’ is displayed on the front panel.
• If the self-test fails, ‘‘FAIL’’ is displayed and the
ERROR
annunciator turns
on. If repair is required, see chapter 5, ‘‘Service’’, for further details.
• If self-test passes, you have a high confidence that the pow er suppl y is
operational.
Performance Verification Tests
These tests should be used to verify the power supply’s specifications following
repairs to specific circuits. The following sections explain all verification
procedures in de tail. All of the performance test limits are shown in each test.
