TEST METHOD

Test condition is 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,
