Agilent Technologies E1441A user service Performance Verification Tests

Performance Verification Tests

The performance verification tests use the function generator's specifications listed in “Agilent E1441A Specifications” on page 135.

You can perform four different levels of performance verification tests:

•Self-TestA series of internal verification tests that give a high confidence that the function generator is operational.

Q• Quick Verification A combination of the internal self-tests and selected verification tests.

P	• Performance Verification Tests An extensive set of tests that are
	recommended as an acceptance test when you first receive the
	function generator or after performing adjustments.

O• Optional Verification Tests Tests not performed with every calibration. These tests can be used to verify additional instrument specifications following repairs to specific circuits.

In all cases, the function generator’s command set is used to configure its output. Use the "Agilent E1441A" column in the following verification tables to determine which commands to use and what parameter value should be sent with them.

Self-TestA power-onself-test occurs automatically when you turn on the function generator. This limited test assures you that the function generator is operational.

A complete self-test runs a series of tests and takes approximately

10 seconds to execute. If all tests pass, you can have a high confidence that the function generator is fully operational.

If the self-test fails, the faceplate Errors LED turns on.

Use the following command to perform a self-test:

*TST?

Returns “0” if the self-test passes or “1” if it fails. If the self-test fails, an error message is also generated with additional information on why the test failed. Use the SYSTem:ERRor? command to read the error queue. See “Self-Test Errors” on page 147 for more information.
