Note *1:Test with each center carrier frequency under the test condition shown below.

*2:Place major axis of elliptic lens in horizontal direction and minor vertical.

*3:Four types of frequency :36.0, 36.7, 38.0, 40.0KHz

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

in case light source temperature2856°K,

Ee=100Lx, VR=5V

Carrier frequency is adjusted to

center frequency of each product
