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,
Sensitivity S=26nA/Lx
