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 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 Agilent 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.
