Performance Verification Tests
The performance verification tests use the power supply's specifications listed in
chapter 1, "Specifications", starting on page 15.
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 can be used to verify the power
supply's specifications following repairs to specific circuits. The performance test
procedures must be performed on each output.
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 key (actually any front
panel keys except the key) and the power-line switch simultaneously and then
continuing to press the 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 Agilent
E3631A 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", starting on page 95, 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's 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.
