Test Items

Testing and certification of wireless products is a critical process to ensure compliance with relevant regulations and standards, and to guarantee performance, safety and reliability.

The main test items include:

1. Radio Frequency (RF) Performance Test

①　Transmit power measurement and power spectral density analysis

②　Frequency range verification and frequency stability test

③　Modulation characteristic inspection and modulation accuracy evaluation

④　Spectrum mask test and occupied bandwidth measurement

⑤　Adjacent Channel Leakage Ratio (ACLR) and Spectrum Emission Mask (SEM) test

2. Electromagnetic Compatibility (EMC) Test

①　Radiated Emission Test: Measures electromagnetic radiation generated by the equipment

②　Conducted Emission Test: Checks electromagnetic interference conducted through power or signal lines

③　Immunity Test: Including Electrostatic Discharge (ESD), Electrical Fast Transient (EFT), Surge, RF field interference, etc.

3. Safety Test

①　Electrical Safety Test: Insulation resistance, withstand voltage test, leakage current, etc.

②　Battery Safety Test: Overcharge, over-discharge, short circuit, high temperature, etc.

③　sar test (Specific Absorption Rate): Measures the impact of RF radiation on the human body

4. Wireless Protocol Conformance Test

①　Bluetooth Certification (BQB): Ensures compliance with Bluetooth SIG standards

②　Wi-Fi Certification: Ensures compliance with Wi-Fi Alliance standards

③　Cellular Network Certification: Such as LTE, 5G, etc., ensuring compliance with 3GPP standards

5. Environmental Adaptability Test

①　High and low temperature test and humidity test

②　Water and dust proof test (IP Rating Certification)

③　Shock and vibration resistance test

These test items ensure that wireless products meet the stringent requirements of major global markets in terms of performance, safety and compliance, providing technical support for the smooth launch of products.
