To meet the power supply test requirements of today’s environment, the Model 8000 comes standard with an off-the-shelf pre-written test item library covering most industry standard power supply tests. The comprehensive test items covers 7 categories of power supply testing requirements, which includes output performance, input characteristics, regulation tests, timing and transient, and protection tests. Users may also create new test items by using a special test item editing function. This gives users the capability to expand the test library unlimitedly.

Customized Test Fixtures

The test fixture, a device that interfaces between the ATS and UUT, is necessary for automated testing. Due to different form factors and various connector types, it is impossible to find an off the shelf test fixture that can fit all test requirements. The Chroma 8000 ATS support team not only helps plan and develop the ATS, but the also provide their expertise to tailor a test fixture to the customer’s needs.

Comprehensive Test Items

The Model 8000 automatic power supply test system comes standard with an off-the-shelf test item library covering most industry standard power supply tests. Unlike traditional ATE software, users do not need to have programming language background to create new test items. Instead the Model 8000 allow users to use pre-compiled test items and to simplify defining test conditions and specifications.

The comprehensive test items cover 7 categories of power supply testing requirements. "Output Performance" checks the general performances of the UUT. "Input Characteristic" verifies the input parameters of a power supply. "Regulation" tests the stability of the UUT under varying line-in and loading changes. "Timing & Transienst"measures the transient state during turn-on, turn-off or when events occurred. "Protection Tests" triggers the protection circuit of the power supply. Finally, the "Special Test" and the "Special Features" provides means to test the most sophisticated power supplies when unique test routines are needed.
