Verification Tests
Introduction This chapter describes the verification tests for the Agilent E1346A Single
Ended Relay Multiplexer. The three levels of test procedures described in
this chapter are used to verify that the Agilent E1346A:
• is functional (Functional Verification Test)
• meets selected testable specifications (Operation Verification)
• meets all testable specifications (Performance Verification)
Test Conditions/
Procedures
See Table 1-1 for test equipment requirements. You should complete the
Performance Verification tests at least once a year. For heavy use or severe
operating environments, perform the tests more often. The verification tests
assume that the person performing the tests understands how to operate the
mainframe, the multiplexers, and the specified test equipment. The test
procedures do not specify equipment settings for test equipment except in
general terms. It is assumed that a qualified, service-trained technician will
select and connect the cables, adapters, and probes required for the test.
Performance
Test Record
The results of each Performance Verification test may be recorded in Table
2-2, Performance Test Record, at the end of this chapter. You can make a
copy of this form, if desired.
Verification Test
Examples
Each verification test procedure includes an example program that performs
the test. All example programs assume the following configuration:
• HP 9000 Series 200/300 computer
• BASIC programming language
• Multiplexer address 70914
• Multiplexer card number 1
• Agilent 3458A Digital Multimeter (DMM)
