FCC Testing Certified Lab

The Federal Communications Commission (FCC) certification is a crucial regulatory process ensuring that electronic products entering the U.S. market comply with relevant electromagnetic compatibility (EMC) and wireless communication standards. The fcc certification testing primarily includes the following aspects:

Electromagnetic Compatibility (EMC) Testing

1. radiated emission testing – Evaluates the electromagnetic energy emitted by the product through space without a physical connection. The test frequency typically ranges from 30 MHz to GHz.

2. Conducted Emission Testing – Measures electromagnetic interference (EMI) conducted through power lines, signal cables, and other conductors, primarily for low-frequency interference between 150 kHz and 30 MHz.

3. Antenna Terminal Disturbance testing – For devices with external antennas (e.g., televisions), this test examines the interference generated at the antenna port.

Radio Spectrum Compliance Testing

1. RF Output Power Testing – Ensures that the radio frequency (RF) transmission power of the device complies with regulatory limits. Excessive or insufficient power levels can affect normal device operation or cause interference with other equipment.

2. Spectrum Characteristics Testing – Evaluates the device's frequency-domain performance, including bandwidth, harmonic distortion, and spurious emissions, which reflect the device's stability and reliability in communication.

3. Other Radio Performance Tests – Includes frequency error, occupied bandwidth, modulation characteristics, adjacent channel leakage power ratio (ACLR), and out-of-band emissions.

Safety Testing

Ensures that the device does not pose risks such as electric shock or overheating during usage, confirming compliance with relevant safety standards.

Other Testing Items

Depending on the product type and application, additional tests may be required, including:

- Ramp Emission Testing

- Current Emission Testing

- Transient Emission Testing

- Flicker Interference Testing

- Frequency Stability and Modulation Characteristics

- Effective Radiated Power (ERP)

- Transmitter and Modulation Frequency Response

- Modulation Bandwidth System for Broadband Devices

- Frequency Stability Under Low Voltage Conditions

fcc standards

- Part 15 – Covers information technology equipment, cordless phones, satellite receivers, television interface devices, receivers, and low-power transmitters.

- Part 18 – Regulates electromagnetic interference (EMI) standards for industrial, scientific, and medical (ISM) equipment.

- Part 22 – Public mobile communication services.

- Part 24 – Personal communication systems, including licensed personal communication services.

- Part 25 – Satellite communication services.

FCC Certification Application Process

The steps for applying for FCC certification are as follows:

1. Submit an application form (our company provides a blank application form).

2. Sign a testing service contract with our company.

3. Provide product samples for testing, along with relevant documents such as electrical schematics, external/internal photos, oscillator circuit diagrams, user manuals, nameplate labels, and product operation descriptions (requirements vary by product).

4. Once the testing is successfully completed, we will submit the application materials to an FCC-authorized certification body.

5. After obtaining FCC certification, the company can legally use the FCC mark on its products.

### Notes:

1. All documents must be in English.

2. To shorten the certification period, it is recommended to submit materials in electronic format.

3. Additional supplementary materials may be required for special cases during the certification process.
