Overview
The Feasa Legend is built for production environments where the LED count is high. A central Hub controls up to eight Satellite modules, enabling a full system to test 160 LEDs in a single capture cycle.
As LED counts continue to increase, manufacturers need test systems that scale without sacrificing speed. The Legend Hub communicates with up to eight Satellite modules, enabling simultaneous measurement of up to 160 LEDs while supporting stand-alone pass/fail decisions for high-throughput end-of-line production.
Its modular architecture makes expansion straightforward as products evolve, while intelligent software supports rapid pass/fail testing across multiple product variants—capturing up to 160 LEDs in as little as 0.8 seconds.
