Operation
Verification
Test
The procedures in this section are used to provide a high level of confidence
that the FET Multiplexer is meeting published specifications. The Operation
Verification Test is a subset of the Performance Verification Tests and is
suitable for checkout after performing repairs.
The Operation Verification Test is performed by completing the Closed
Channel Resistance Test (Test 2-1) as described in the Performance
Verification Test procedures. This test is usually sufficient to verify that the
FET Multiplexer is meeting its specifications.
Performance
Verification
Tests
The procedure in this section is used to test the FET Multiplexer’s electrical
performance using the specifications in Appendix A — Specifications of the
appropriate FET Multiplexer User’s Manual as the performance standard.
There are two performance verification tests; Test 2-1: Closed channel
Resistance Test, and Test 2-2: Leakage Test. These tests are suitable for
incoming inspection, troubleshooting, and preventive maintenance.
Test Fixture A Test Fixture is required to run the Performance Verification tests. Figure
2-1 shows the connections using an Agilent E1351A Terminal Block for the
test fixture. The Agilent E1352A, E11353A, E1357A and E1358A
Terminal Blocks are not recommended as test fixtures. You may want to
order an extra terminal block to use as a test fixture, so you don’t have to
