Section III
VERIFICATION
3-1 INTRODUCTION
This section contains test procedures that check the
operation of the power supply. Four types of procedures are
provided: Operation Verification Tests, Performance Tests,
Extended Tests, and Temperature Coefficient Tests.
The Operation Verification Tests comprise a short procedure
to verity that the supply is performing properly, without
testing all specified parameters. The Performance Tests
provide a more complete test of the supply by testing most
of the specifications listed in Table 1-1 in the Operating
Manual (Agilent Part No. 06626-90001).
The Extended and Temperature Coefficient tests are similar
to the Performance tests except that they are conducted in a
controlled environment and require a longer period of time
to complete each test.
If failures are encountered or out of specification test results
are observed, refer to the Troubleshooting Procedures in
Section IV in this manual. The troubleshooting procedures
will determine if repair and/or calibration is required.
Calibration procedures are provided in Appendix A of the
Operating Manual.
NOTE
For mechanical reasons, there are two different
assemblies for the 50W/2A output boards
When ordering replacement output boards,
determine the appropriate assembly number
from “Chassis Boards” section of Table 5-5.
Note that the replaceable parts on both
50W/2A assemblies are the same (see Tale 5-7).
3-2 TEST EQUIPMENT REQUIRED
Table 3-1 lists the equipment required to perform the tests in
this section. The tests are performed by sending commands
to and receiving data from the supply under test via the GP
IB. An Agilent Series 200 or 300 computer is used as the GP
IB controller. Tests that do not verify readback via the GPIB
can also be performed manually from the supply’s front
panel and, consequently do not require use of a controller.
The tests should only be performed by qualified
personnel. During the performance of these tests,
the output of the supply being tested may voltage
levels above safe levels.
3-3 OPERATION VERIFICATION TESTS
To assure that all outputs of your supply are performing
properly, without testing all specified parameters, perform
the test procedures outlined.
a. Perform the turn-on and checkout procedures
given in Section III, paragraphs 3-3 thru 3-9, of the
Operating Manual. These procedures include a
power-on self test.
b. Perform the performance tests listed below on each
output of your supply.
Voltage Programming and Readback Accuracy
(paragraph 3-12)
CV Load Effect (paragraph 3-13)
CV Noise (paragraph 3-15)
Overvoltage Protection Tests (paragraph 3-18)
Current Programming and Readback Accuracy
(paragraph 3-21)
CC Load Effect (paragraph 3-23)
3-4 PERFORMANCE TESTS
3-5 Introduction
The following paragraphs provide test procedures for
verifying the supply’s compliance with the specifications
listed in Table 1-2 of the Operating manual. The procedures
cover all models in the series of Multiple Output Power
Supplies. The performance test procedures must be
performed on each output. Figure 3-1 shows the outputs
present and output ranges on each model.
The test procedures that follow give settings and results for
each type of output that may be tested. There are two types
of outputs: 25 Watt and 50 Watt. Make sure that you use the
test settings and results listed for the particular output
