Troubleshooting
This section will help isolate a failing assembly.
Visual Checks
Before installing or operating the module, visually inspect the rear panel and
front panel connectors for bent pins. Inspect circuit boards for evidence of arcing
or excessive heat.
If a module does not respond to commands, verify the Logical Address setting.
The Keysight E1418A User’s Guide describes this switch setting.
Catastrophic Failures
If a module does not respond, verify the power fuses F1, F2, F3 and F4.
Self-Test
The internal self-test can be used to isolate most failures of the module. The
major assemblies of the Keysight E1418A are available on an exchange basis.
Use the following SCPI Common Command query to initiate a module self-test.
/* Start the Self-test*/
*TST?
/* Enter the 16-bit integer returned*/
The query will return a +0 if no errors are encountered. Any return other than +0
indicates a failure. The command returns the first test to fail, additional failures
are possible.
The *TST? query initiates a full self-test. You can obtain the complete test results
by using the TEST:TST:RESults? query. This query returns an array of 100
integers representing the results of each self-test.
Use the following SCPI commands to initiate a self-test and obtain complete
results.
/* Start the Self-test*/
*TST?
/* Enter the 16-bit integer returned*/
/* If the returned value is not +0, send*/ TEST:TST:RES?
/*Enter an array of 100 integers*/
