Test method

The specified electro-optical characteristics are valid under the following conditions.

1. Measurement environment

A place without extreme light reflections.

2. External light

The environment contains an ordinary, white fluorescent lamp without high frequency modulation. The

color temperature is 2856K and the illumination at the IR receiver is less than 10 Lux (Ev≦10Lux).

3. Standard transmitter

The test transmitter is calibrated by using the circuit shown in figure 2. The radiation intensity of the

transmitter is adjusted until Vo=400mVp-p. Both, the test transmitter and the photo diode, have a peak

wavelength of 940nm. The photo diode for calibration is PD438B (

λp=940nm, Vr=5V).
