Matrix Module
Functional
Verification
The Functional Verification Test for the Agilent E1465A/E1466A/E1467A
matrix modules 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 matrix 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.
NOTE
If a terminal module is not connected, the module defaults to a 4 x 64
configuration and the device description is E1466A.
Example
An example follows which uses an HP 9000 Series 300 computer with
BASIC and a matrix module address of 70915.
10 OUTPUT 70915;"*TST?" Send the self-test command
20 ENTER 70915;A Get response
30 PRINT A
40 END
Operation
Verification
The procedures in this section are used to provide a high confidence that the
matrix module is meeting published specifications. The Operation
Verification tests are a subset of the Performance Verification tests and are
suitable for checkout after performing repairs.
For the Agilent E1465A/E1466A/E1467A matrix modules, 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 E1465A/E1466A/E1467A Relay Matrix Switch Modules User’s
Manual as the performance standards.
