FCC (Federal Communications Commission)
The FCC an independent agency of the U.S. government established in 1934. The FCC by controlling radio wide
Broadcasting, television, telecommunications, satellite and cable coordinate national and international communications. Many radios should
the FCC approval is required for applications, communications and digital products to enter the U.S. market
——The FCC certification. The FCC commission investigates and studies all phases of product safety to find solutions
The FCC also includes the detection of radio devices, aircraft and so on
FCC wired product testing content, FCC VoC
The FCC regulates only electromagnetic interference. Electromagnetic Interference is divided into two types
The following ways:
1. Conduction interference
propagates through power lines, signal lines, and other conductors, and the FCC requires frequencies from 150Khz to
At 30Mhz, the interference at low frequency is mostly conducted interference.
2. Radiation Emission
Spread through space. From 30Mhz to 1Ghz, most of the interference at high frequency is radiation interference.
Usually, both kinds of interference can coexist.
3. Antenna disturbance.
This applies to devices with external antennas. Such as TV.
Common FCC certification test content
FCC only controls electromagnetic interference, which is mainly divided into the following ways:
1. Radiation Emission propagates through space. From 30Mhz to 1Ghz, most of the interference at high frequency is radiation interference. Usually, both kinds of interference can coexist.
2.Conduction Emission spreads through the power line, signal line and other conductors. FCC requires frequency from 150Khz to 30Mhz, and the interference at low frequency is mostly Conduction interference. Mainly for electronic products connected to the power grid.
3. antenna end harassment. This applies to devices with external antennas, such as TVS. FCC certification testing standards: FCC PART 15, FCC PART 18.
FCC certification test program
