Performance Verification Tests
The performance verification tests use the power supply's specifications listed in
the E3632A User’s Guide.
You can perform two different levels of performance verification tests:
– Self-test
A series of internal verification tests that provides high confidence that the
power supply is operational.
– Performance verification tests
These tests can be used to verify the power supply specifications following
repairs to specific circuits.
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 pressing the
Recall key (actually any front
panel keys except the Error key) and the power-line switch simultaneously and
then continuing to press the Recall key for 5 seconds. The complete self-test will
be finished in 2 more seconds.
You can also perform a self-test from the remote interface (see chapter 3 in the
E3632A 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 2, “Service” for further details.
– If self-test passes, you have a high confidence that the power supply is
operational.
Performance verification tests
These tests can be used to verify the power supply specifications following repairs
to specific circuits. The following sections explain all verification procedures in
detail. All of the performance test specifications are shown in each test.
