Performance Verification Tests
The performance verification tests use the power supply’s specifications listed in
“Specifications” on page 17.
You can perform two different levels of performance verification tests:
– Self-Test
A series of internal verification tests that provide high confidence that the
power supply 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 automatically when you turn on the power supply.
This limited test assures you that the power supply is operational.
The complete self-test is enabled by holding down key (actually any front
panel keys 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 self-test from the remote interface (see chapter 3 in the
Keysight E3633A and E3634A User’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 power supply 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 detail. All of the performance test limits are shown in each test.
