FEASA™ LED ANALYSER
4Pages

The Innovative Solution for Testing LEDs The Feasa Analyser is an innovative solution for testing multiple LEDs simultaneously for Color and Brightness. There are two Models – Feasa I(ICT) and Feasa F(Functional). These can be ordered in 3, 5, 10 and 20 Channel configurations. When choosing which Model is most suitable for your application there are a number of issues to consider. In this regard the choice of Interface is important. INTERFACES Feasa I USB RS232 20 Pin Port – Frequency Out 20 Pin Port – Synchronous Serial Daisy Chain External Trigger Input USB offers a simple interface to the LED Analyser with no requirement for an additional power supply. Baud rates up to 921600 baud are available, default 57600. The RS232 Serial Port is easy to use with a max baud rate of 115200. It requires the use of an external power supply. The 20pin ICT Port can be used in either Frequency Out or Synchronous Serial Mode. Frequency Out The Frequency Out protocol can be used where access to an RS232 Serial Port is not available. Three frequencies are used to represent the Color and Intensity of the LEDs. - Synchronous Serial Port The Synchronous Serial protocol is suitable when tester resources are limited or no other options are available. Daisy Chain Multiple LED Analysers can be connected together using the Daisy Chain Connectors. Only one RS232 Serial Port or USB Port is required to connect up to 30 LED Analysers. External Trigger Input The Feasa I provides an External Trigger Input which can be used to synchronise LED measurements with an external event such as an LED switching on.

The Innovative Solution for Testing LEDs TEST TIME The speed of the test is dependent on the intensity of the LEDs being tested, i.e. Bright LEDs have a shorter Test Time, Dimmer LEDs have a longer Test Time. The capture (measurement) of up to 20 LEDs is done in parallel and can be achieved in times as fast as 102ms depending on the Intensity (Brightness). The data is read back from each fiber sequentially and takes approximately 5ms per fiber, for example: Ultra High Brigh LEDs 1 LED Capture Time is 2ms and Read Back is 5ms, Total 7ms 20 LEDs Capture Time is 2ms and Read Back is 100ms,...
