Wireless electronic products have always had a high degree of fierce attention in the Japanese market. Wireless products need to pass telec certification before they can be sold in Japan. Then let's take a look at the items for wireless product telec certification testing?

The specific standard for 2.4GHz Bluetooth products is MIC No.88 Annex43. The following are the specific test items we should consider according to the standard, mainly as follows:

Wireless product telec certification test project

1. Frequency Error Measurement (Frequency Error Measurement);

2. Coupling bandwidth / carrier frequency bandwidth test (Occupied Bandwidth and Spread-spectrum Bandwidth / Factor);

3. Unwanted Emission Intensity Measurement;

4. Antenna Power Error Measurement (Antenna Power Error Measurement);

5. Receiver spurious disturbance test (Limitation of Collateral Emission of Receiver Measurement);

6. EIRP antenna power test (Transmission Antenna Gain (EIRP Antenna Power) Measurement);

7, 3dB lobe bandwidth test (Transmission Radiation Angle Width 3dB Bandwidth Measurement);

8. Duty Cycle Measurement;

9. Retention time test (retention time);

10. Interference Prevention Capability & Carrier Sense Capability Measurement (Radio Interference Prevention Capability & Carrier Sense Capability Measurement).
