Functional Verification Test
The Functional Verification Test for the Keysight E1458A module consists of
sending the *TST? command and checking the response. This test can be used to
verify that the module is connected properly and is responding to a basic
command.
Procedure
1 Verify that the module is properly installed in mainframe.
2 Verify that the mainframe has passed its power-on test.
3 Send *TST? to the module (see example following).
4 The return should be as follows:
0
Example
An example follows which uses an HP 9000 Series 300 computer with BASIC and
a module address of 70918.
10 INTEGER A
20 OUTPUT 70918;"*TST?" Send the test command
30 ENTER 70918;A Get response
40 PRINT A
50 END
If the primary address setting, secondary address setting, or the
interface select code is set incorrectly, the module will not respond.
Verify proper address selection before troubleshooting.
