keysight technologies medalist i3070 led test technical overview
2 the i3070 led test sensors and led signal conditioner (mux) card are installed in the i3070 test fixture simi- lar to our vtep solutions. thirty-two i3070 led test sensors can be wired to each i3070 led signal conditioner (mux) card, and four i3070 led signal conditioner (mux) cards to one i3070 led test card in a utility card or an i3070 led test box. the i3070 led signal conditioner (mux) card in the fixture is then connected to the i3070 testhead electronics via the i3070 led test card plugged into a utility card or a i3070 led test box. the i3070 led test box saves a hybrid card slot and is mounted within the i3070 test head. i3070 led test unique features the i3070 led test delivers several industry firsts: C turns on multiple leds simultaneously using an i3070 patented unpowered digital test method C acquires the peak, base or instantaneous wavelengths of the led color and returning the measurement in nanometers (nm) C measures the led luminosity in w/cm 2 C proprietary architecture will send digital stimuli, measure the leds color and luminosity and returning results of up to 128 leds in less than 1.3 seconds C uncompromising repeatability achieved through a shroud tube design to shield noise (ambient light) from surrounding leds C smallest led sensor size in the market allows direct sensor placement over leds spaced 5.5 mm apart (center-to-center) enabling a high signal-to-noise ratio (snr) figure 1. set-up diagram for i3070 led test.

3 i3070 led test unique features state-of-the-art led sensor design the i3070 led test has been designed to enhance the experience of testing leds on the i3070. the small sensor design improves the measurement snr as it can be installed directly over the led. a shroud tube can be fitted into the sensor to block out ambient light from surrounding leds, reducing noise and improving the snr. if the led location prevents a direct sensor mount, a light pipe or optical fiber cable can be used to transport the led light to the sensor. the sensor can be programmed to return peak (highest), base (lowest) or instantaneous reading of the monochromatic leds color and luminosity. for non-monochromatic leds, leds designed to output mul- tiple wavelengths but perceived by the human eye as a single color, the sensor can be programmed to return a single wavelength with the sensor set to multimode. led luminosity can be influenced by temperature and other factors. after turning on the led, it is desirable to delay the luminosity measure - ment until it reaches its optimum operation state. the i3070 led test software gives full flexibility to the test programmer to set the sensor to trigger, learn and evaluate the led. a gain is available to increase the led light input and a prescaler to set the sensitivity of the sensor. the i3070 led test sensor has been designed to discern any luminosity changes greater than 3% enabling the i3070 led test system to be accurate to within 10% of the learned luminosity value. a comprehensive i3070 led test experience the i3070 led test is integrated with software tools to enhance the programmer experience in develop - ing, debugging and deploying the led tests on i3070. the software tools will automate the led test generation and fixture files while a debugging tool aids the programmer to learn and validate the led test results prior to releasing the tests to manufacturing. the i3070 led test is supported on i3070 system software release 8.3 or greater. i3070 led test speciications measurement range units accuracy color (hue) 400 to 660 nm 3 nm luminosity 0 to 18,000 w/cm 2 10% i3070 system requirements software release 8.3 hardware C utility card with i3070 led test card or C i3070 led test box i3070 led test part numbers to use when ordering: i3070 led test accessories description n1124a-001 i3070 led test sensor (pack of 32) n1124a-002 i3070 led test signal conditioner (mux) card n1124a-003 i3070 led test card n1124a-005 i3070 led test starter kit includes: C receptacle socket pin for 32 i3070 led test sensors C light shroud tubing for i3070 led test sensors C mounting screws for two i3070 led test multiplexer cards N1128A-001 i3070 led test box
