Types of Radio Frequency Interference

Many of today’s products use radio frequency, or RF, technology. That means there is a lot of RF emissions that a person may come in contact with in their daily life. These emissions can impact the way certain devices work, especially if they have little or no RF immunity. An RF immunity test is a good way to make sure your product will work in certain conditions. Here are some of the products made today that require some amount of RF immunity.

Medical Equipment

RF energy is used in a variety of medical situations, both cosmetic and health related. Some cosmetic treatments include fat reduction and skin tightening treatments while on the health front, there are MRI machines and other imagining machines. MRIs especially need some level of RF immunity to prevent other ambient RF energy from distorting the pictures doctors need in order to treat and diagnose their patients.


Radio and television broadcasting output a lot of RF energy, but the tools used to do this also need to undergo an RF immunity test. Without some RF immunity, there can be distorted images or pictures being broadcast to consumers. Another telecommunications technology that needs some level of RF immunity is very common – the cell phone. For the same reasons radio and television need some RF immunity, cell phones do as well to prevent garbled or dropped phone calls.

Industrial Sealing

Some manufacturers use RF energy to heat to mold or seal certain materials in a durable and seamless way. Too much interference can affect how these machines work and create defects in a product. That is why an RF immunity test is an important step in creating machines to be used in manufacturing.

Radio frequency waves are just about everywhere and they can interfere with a variety of machines and tools. An RF immunity test should always be performed for a device that uses RF energy to make sure it can perform in multiple environments.
