Switch Module Functional Verification
The Functional Verification Test for the Agilent E1463A 32-Channel Form C
Switch Module consists of sending the
*TST? command and checking the response.
This test can be used at any time to verify that the device is connected properly and
is responding to basic commands.
Procedure 1. Verify that the Switch Module is installed in the mainframe and that
the mainframe has passed its power-on test.
2. Send the *TST? command to the device (see example following).
3. The device will return an error code. Any non-zero error code
indicates a self-test failure. See Table 4-4 for a description of self-test
error codes.
Example An example follows which uses an HP 9000 Series 300 computer with BASIC and
a Switch Module address of 70915.
10 OUTPUT 70915;"*TST?" Send the self-test command
20 ENTER 70915;A Get response
30 PRINT A

Operation Verification
The procedures in this section are used to provide a high degree of confidence that
the Switch Module is meeting published specifications. The Operation Verification
tests are usually a subset of the Performance Verification tests and are suitable for
checkout after performing repairs.
For the Agilent E1463A Switch Module, Operation Verification is performed by
completing the Closed Channel Resistance Test as described in the Performance
Verification test procedures (Test 2-1). This test is usually sufficient to verify that
the instrument is meeting its specifications.
Performance Verification
The procedures in this section are used to test the module’s electrical performance
using the specifications in Appendix A of the Agilent E1463A 32-Channel Form C
Switch Module User’s Manual as the performance standards.
