s TEST METHOD

Test condition in as follows:

(1) Standard transmitter:

Transmitting waveform is shown in Fig.1

Transmitting power should be adjusted

so that output voltage Vout will be

400mVp-p.(Test circuit is shown in Fig.2)

Regarding IR LED used for transmitter,

λp=940nm, ∆λ=50nm.

Regarding photo diode,

Sensitivity S=26nA/Lx

in case light source temperature2856°K,

Ee=100Lx, VR=5V

(2) Test system: Shown in Fig.3.
