Radio Frequency (RF) is a frequency associated with radio waves, within the electromagnetic spectrum. On application of RF current to specialized antennas, an electromagnetic field is generated, which then leads to generation of RF waves. This waves travel through the surrounding media, which might be air or water. Several electronic devices are based on propagation of radio frequency waves. Radio frequency waves are widely used for telecommunications. Applications in video broadcasting, radio communications and satellite communications are generally achieved by utilization of RF electronic components. Additionally, RF energy is also used for several industrial and healthcare applications. RF test equipments are primarily utilized for testing of RF components and RF electronics, to ensure their proper functionality. RF testing is done to ensure that a device is able to function properly under an electromagnetic environment, and should not be emitting intolerable electromagnetic radiat...
