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 verification tests that provide hig h
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 powe r-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 91, 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.
