RF

 

The general testing fields of wireless products include electromagnetic compatibility (EMC) testing, RF radio frequency testing, safety testing, safety testing SAR testing, etc. Among them, RF radio frequency testing is one of the important testing fields, and it is also a field with a relatively large amount of testing.

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

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

(3) GSM RF test (spectrum analyzer, base station, power divider, attenuator)

(4) WCDMA FCC RF test (spectrum analyzer, base station, power divider, attenuator)

FCC certified RF devices fall into the following categories:

1. Included radiator (Part 15, Part A)

2. An incidental radiator (defined in Section 15.3(n)) is an electrical apparatus not designed to be used intentionally, to intentionally generate or to intentionally emit radio frequency energy above 9 kHz, however, an accidental radiator may produce above 9 kHz by-products of radio emissions and cause radio interference.
Products classified as included with a heat sink assembly do not require device authorization. Nevertheless, the included heat sink is regulated under the general operating conditions of Section 15.5, if harmful interference exists, the user must discontinue operation and remedy the interference. Manufacturers and importers should use good engineering judgment before selling and selling these products to minimize possible interference (section 15.13).
Examples of products classified as included with radiators include: AC and DC motors, mechanical light switches, basic power tools (without digital logic).

Unintentional radiator (Part 15, Parts B and G) An unintentional radiator (defined in 15.3(z)) is a design that, by design, uses digital logic, or operates at radio frequencies The electrical signals used in the product, or transmitted over a connection line to associated equipment to transmit radio frequency signals, are not intended to transmit RF energy wirelessly by radiation or induction.

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

Examples include: coffee makers, 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 radiator (Part 15, Parts C to F and H) An intentional radiator (defined in Section 15.3(o)) is a device that intentionally generates and emits radio frequency energy by radiation or induction, which can Operate without personal permission.

Examples include: wireless garage door openers, wireless microphones, RF universal remotes, cordless phones, wireless alarm systems, Wi-Fi transmitters, and Bluetooth radios.

Industrial, Scientific and Medical Equipment (Part 18)

When electrical and electronic products are used to provide RF energy outside of telecommunications applications, such as to produce physical, biological or chemical effects such as heating, gas ionization, mechanical vibration and acceleration of charged particles, these devices comply with FCC rules 47 CFR Part 18.

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