Immunity Testing

The inverse of emissions testing, immunity testing subjects a product to various RF phenomena to see if it affects the product's performance. If you have considered marketing your device internationally, you know that European Union member countries require immunity testing for products sold within their borders. We are capable of performing a full spectrum of immunity tests to guide you through this critical series of tests, significantly reducing your time to market.

We conduct electrostatic discharge (ESD), electrically fast transient (EFT), surge and power line disturbances. Our Semi-Anechoic Test chamber is capable of testing products from 26 MHz to 3 GHz and is designed with an oversized test volume to allow us to test products up to three meters in length in a single pass. If your product has a vulnerability, we can find it and help you fix it.
