What are the test items for RF products?
In short, any RF product should be tested in two aspects.
1. RF;
2. EMC.
RF products are different from EMC in that RF products are intentionally launched while EMC is unintentionally launched. RF products transmit useful signals with the help of a certain frequency band, so as to achieve the purpose of transmitting information. In addition to the useful signal, there will be different degrees of harmonic signal, so the useful signal (main frequency) and harmonic should be limited. Including output power, power density, bandwidth, frequency error, spurious emissions, etc.
EMC is an unintentional launch that meets functional or performance requirements. When RF products work normally after TX and Rx are connected, it will cause interference to other systems or individuals, so EMC testing is also essential. Test items include radiation, conduction, harmonics, flick, EFT, surge, dips, ESD, CS, RS, etc. Different products choose different test items, for example, for battery powered RF products, when testing EMC, only radiation, ESD and RS need to be tested.
