F.C.C. Certification

One of the most essential compliance tests for electronic devices is FCC testing.

Electronic devices by considering what belongs to which categories, intentional or unintentional radiation devices, and are marketed in which country or geographical area needs to meet the country’s requirement emission standards. Government regulators try to avoid interference between wireless communication and radio frequencies emission Intentional and unintentional radiators.


Intentional and Unintentional Radiators

The intentional radiators category refers to electronic devices whose operation is based on emission RF waves. This equipment is designed and provides for wireless communication targets (Bluetooth devices, WiFi devices, cellular, …)

Unintentional radiators – like a digital camera – are electronic devices that broadcast unwanted radio signals through space or power lines. That causes interference and produces noise signals in neighborhood devices’ operation.


All digital equipment consists of several electronic components and circuits. When an electronic device operates, an unintentional radiator generates some level of radiated and conducted emission.

Radiated emissions are unintentional energy scattering through the air in the form of electric, magnetic, or electromagnetic fields. In contrast, conducted emissions are the energy that travels in power cables or attached signal cables. Excessive levels of emissions may interfere with the operation of nearby electrical equipment. These radiated or conducted emissions generate noise in electronic devices, called electromagnetic interference (EMI).

Next comes electromagnetic compatibility (EMC). The ability of an electronic device to operate without interfering with other devices and to function correctly in some level of radiated or conducted emissions. All PCB design processes must be compliant to above mentioned requirements in order to be safe to be used. 

FCC Compliance Testing

Each country and geographical region has its own emission requirements standards and its own approved certificates, approved certificates for Canada and USA are Innovation, Science & Economic Development (ISED) and Federal Communications Commission (FCC) respectively.

FCC certification is required for electronic devices marketed and sold in the United States that oscillate at 9 kHz to 3 THz (3.000 GHz). Title 47 of the Code of Federal Regulations (CFR) points out telecommunication is the reference for FCC’s rules and regulations. Title 47 includes different parts. Part 15 represents all radio frequency device categories and related requirements and standards for them.

In part 15 CFR systems (Code of Federal Regulations) digital devices divide into two testing classes:

Class A and Class B. Class A digital device has higher emission limits and is intended for industrial, institutional, or commercial applications. In contrast, Class B digital devices are for use in a residential environment and consumer equipment that requires stricter testing due to reduced emission limits. examples of such devices include personal computers, calculators, and similar electronic devices.

Arshon technology has been using Nemko Lab as the main source for its certification and compliance purposes.

Type of FCC approval

● Certification

The most important authorization process in EMC qualification in North America  is the FCC certification. The procedure is for the equipment that are likely to harmfully interfere with other RF equipment and signals, therefore F.C.C. Certifications are issued by Telecommunication Certification Bodies (TCBs) like Eurofins MET Labs to assume compliance of the product and they feature a F.C.C. ID on its label.

● Supplier’s Declaration of Conformity (SDoC)

A stricter procedure is typically required for Part 18 devices; Industrial, scientific, and medical (ISM) equipment; or devices like personal computers or peripherals.

It requires an accredited laboratory like Eurofins MET Labs as a party responsible for compliance to measure radio frequency energy from the device at specified frequency spectrum, to ensure that it does not generate higher than accepted energy at specific frequencies. The responsible party, who must be located in the United States, is not required to file an equipment authorization application with the Commission or a TCB. a compliant product features the FCC logo on its label.

● Verification

Verification is the easiest authorization method a device passes to receive an FCC certificate. The verification process is used for digital products with Part 15 components to obtain a part 15 certification.

Part 15 devices only require verification; they do not need approval or a certified FCC logo.

Sometimes we don’t need to follow all the approved certification steps for a device, we can use the pre-certified module for our devices.

Pre-Certified Module:  These modules often include the transmitter module, produced by a manufacturer, tested in a standalone configuration and that has taken all of the steps needed to obtain FCC certification and can be installed into another system. By using these modules, you’ll get the benefit of FCC compliance, but you’ll also be restricted in your choice of antennas.
