Wireless products are generally tested in the field of electromagnetic compatibility EMC test, RF radio frequency test, safety test, safety test SAR test and so on, of which RF radio frequency test is one of the important test areas, but also a large amount of testing in a field.

(1) BT RF test (spectrum meter, Anritsu MT8852B, power divider, attenuator)

(2) WIFI RF test (spectrum meter, power divider, attenuator, power meter)

(3) GSM RF test (spectrum meter, base station, power splitter, attenuator)

(4) WCDMA FCC RF test (spectrum meter, base station, power splitter, attenuator)

FCC certification RF equipment is divided into the following categories:

1. Incidental radiators (Part 15, Part A)

2.Incidental Radiator (defined in Section 15.3(n)) is an electrical device that is not designed to be used intentionally to intentionally generate or intentionally emit radio frequency energy above 9 kHz, however, incidental radiators may generate by-products of radio emissions above 9 kHz and cause radio interference.

Products classified as incidental radiator devices do not require a device authorization. Nonetheless, incidental radiators are conditioned under the general operating conditions of Section 15.5, and if harmful interference is present, the user must cease operation and remedy the interference. Manufacturers and importers should use good engineering judgment to minimize possible interference before marketing and selling these products (Section 15.13).

Examples of products classified as incidental emitters include: AC and DC motors, mechanical light switches, basic power tools (without digital logic).

Unintentional Radiators (in Part 15, Part B and Part G)

An unintentional emitter (defined in Section 15.3(z)) is a design that uses digital logic by design, or electrical signals operating at radio frequencies used in a product, or that sends RF signals by connecting line transmissions to an associated device, but is not intended to emit RF energy wirelessly by radiation or induction.

Today, most electrical and electronic products use digital logic, operate at frequencies between 9 kHz and 3000 GHz, and are regulated by 47 CFR Part 15 Subpart B. The majority of electrical and electronic products use digital logic and operate at frequencies between 9 kHz and 3000 GHz.

Examples include: coffee pots, watches, cash registers, personal computers, printers, telephones, garage door receivers, wireless temperature probe receivers, RF universal remote controls, and thousands of other types of common electrical and electronic devices that rely on digital technology.

Intentional Radiators (in Part 15, Parts C through F and H)

An intentional radiator (defined in Section 15.3(o)) is a device that intentionally generates and emits RF energy by radiation or induction, and can be operated without personal authorization.

Examples include: wireless garage door openers, wireless microphones, RF universal remote control devices, cordless phones, wireless alarm systems, Wi-Fi transmitters, and Bluetooth radio devices.

Industrial, Scientific and Medical Equipment (Part 18)

When electrical and electronic products are used to provide RF energy for purposes other than telecommunication applications, such as for generating physical, biological, or chemical effects such as heating, gas ionization, mechanical vibration, and acceleration of charged particles, these devices comply with FCC rule 47 CFR Part 18.

Examples include: fluorescent lamps, halogen ballasts, arc welders, microwave ovens and medical diathermy machines.
