FEASA LED Analysers

الوصف

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, *0 and *0 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 very important.

Frequency Out

The Frequency Out protocol can be used where access to an RS**2 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 RS**2 Serial Port or USB Port is required to connect up to *0 LED Analysers.

Led Analyser 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 *0 LEDs is done in parallel and can be achieved in times as fast as 1.2ms depending on the Intensity (Brightness).
The data is read back from each fiber sequentially and takes approximately 5ms per fiber, for example:


Ultra High Brightness LEDs Test Time
- 1 LED Capture Time is 1.2ms and Read Back is 5ms, Total 6.2ms.

- *0 LEDs Capture Time is 1.2ms and Read Back is **0ms, Total **1.2ms.


Dim LEDs Test Time
- 1 LED Capture Time is 1.2s and Read Back is 5ms, Total 1.**5s.

- *0 LEDs Capture Time is 1.2s and Read Back is **0ms, Total 1.3s.
