Overview
The Feasa Legend is designed for production environments where the LED count is too high for a standard single-unit analyser. A central Hub controls up to 8 Satellite Analyser modules, each testing up to 20 LEDs simultaneously β giving a fully populated system the ability to test 160 LEDs in a single capture cycle. Multiple Hubs can be combined for assemblies with even higher LED counts.
The Hub connects to a PC via USB or RS232 and communicates with each Satellite via a 6-pin ribbon cable. A 10-pin connector also provides a remote stand-alone mode β allowing pass/fail decisions to be made at the fixture without a PC present, ideal for end-of-line verification in high-throughput environments.
The Legend GUI automatically learns and stores pass/fail criteria for up to 32 different board versions, reducing the complexity and development time of test programs. With a wide dynamic intensity range, it measures very dim and ultra-bright LEDs on the same PCB in a single test cycle β in as little as 0.8 seconds for a full 160-channel capture.
Built for large LED counts. Trusted globally.
Up to 160 LEDs simultaneously
One Hub controls up to 8 Satellite Analysers, each testing 20 LEDs at once. Full 160-LED capture in as little as 0.8 seconds. Hubs can be combined for larger assemblies with no upper channel limit.
32-board version memory
The Legend GUI automatically learns and stores pass/fail criteria for up to 32 different board versions. Reduces test program development time and simplifies changeover between product variants on the same line.
Stand-alone pass/fail mode
The 10-pin connector enables remote stand-alone operation β limit selection and pass/fail output without a PC. Ideal for end-of-line stations where simplicity and speed are paramount. Wide dynamic range handles dim to ultra-bright LEDs on the same board.
