Chroma has created the industries first LED load simulator for simulating LED loading with our Load module 63110A from our 6310A series Programmable Electronic DC Loads. The 63110A design is able to uniquely simulate real world characteristics of the LED, including the ability to simulate the V-I performance curve and PWM brightness and dimming control features.

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.
