What are Radio and Wireless Tests?

Fun Fact: What is RF?

Radio frequency is abbreviated to RF. Every frequency in the electromagnetic spectrum that is synonymous with radio wave propagation is referred to as RF. An electromagnetic field is generated when RF is applied to an antenna, allowing it to pass, or spread, through space. RF field amplification is seen in a lot of wireless systems. The electromagnetic radiation spectrum includes these wavelengths.

RF Overview

RF energy is used in a wide range of applications including telecommunication, non-communication, and medical devices. The most popular and commonly used source of this energy is telecommunication. RF energy has similarly diverse uses in more specific fields, such as the medical industry. The human body is imaged using RF waves in MRI (Magnetic Resonance Imaging). RF may also be used to kill cancer cells and perform beauty procedures including skin tightening, weight reduction, and cell healing.

Microwave ovens, which use RF energy to heat food, are examples of non-communication devices that use the technology. RF radiation may also be used for heating and sealing in the manufacturing sector. In the same way as a microwave oven cooks food, industrial heaters and sealers produce RF radiation that quickly heats the material being treated.

RF Testing

Before placing a Radio device on the market clients must perform testing for compliance with local regulations. FCC in US, ISED in Canada regulate use of radio devices. Testing depends upon frequency of operation and the final intended use.
Megalab Group offers RF Testing and compliance services in its state-of-the-art facility in Aurora (Greater Toronto Area). Megalab carries accreditations with various bodies globally.
In the European Union, the CE mark applies to Radio devices. Megalab Group can provide test reports which can be used to declare compliance against the CE mark. In Europe Emissions and Immunity requirements apply before a product can be placed on the market. At the same time Product Safety and EMC testing requirements should be complied with for complete approvals.
Following are some of the common test standards we perform testing to standards

Accredited Test Lists

  • FCC 15
  • RSS 210
  • ETSI EN 300-328

Global RF Requirements

Radio frequency conformity is required in the majority of worldwide markets, including the European Union, the United Kingdom, the United States, New Zealand, Canada, Australia, New Zealand, and Japan.

If you import wireless devices or integrate wireless devices into your goods, you must follow the rules of your intended markets. Radio frequency monitoring can also detect issues early, allowing our clients to prevent expensive rework and gain rapid entry to foreign markets.

Services Offered

Megalab can offer pre-scan services for RF tests which can be instrumental in getting your device to market on schedule. Early testing and consultation can detect failures and fixes might be recommended based on the failure detected. EMTS prides itself in client-oriented testing and consultation services.

RF Tests

A radio frequency test is carried out in the 10m EMC chamber where the RF field is measured to detect electromagnetic interference.

In certain economies the system may also be tested for RF immunity, which refers to its ability to withstand interference from other devices. This type of testing entails exposing the system to intervention and evaluating how well it does under such conditions.

How to determine RF Test Interference?

RF interference, is classified into two types: narrow band and wide band.

Narrow Band transmissions have narrow wavelengths and may include continuous wave (CW) or modulated signals. Co-channel and adjacent-channel broadcasts are examples of this kind of bandwidth.

Broadband, the more widely used term, refers to wider wavelengths.

Test standards have established protocols to detect types of interference a DUT can cause. Compliance with national standards minimizes the risk of RF pollution in the end use application.
