What is BS EN 55016‑1‑4- Antennas and test sites for radiated disturbance measurements about?
BS EN 55016‑1‑4 is a safety standard on antennas and test sites for radiated disturbance measurements.
BS EN 55016‑1‑4 specifies the characteristics and performance of equipment for the measurement of radiated disturbances in the frequency range 9 kHz to 18 GHz. Specifications for antennas and test sites are included.
The requirements of BS EN 55016‑1‑4 apply at all frequencies and for all levels of radiated disturbances within the CISPR indicating the range of the measuring equipment.
Who is BS EN 55016‑1‑4- Antennas and test sites for radiated disturbance measurements for?
BS EN 55016‑1‑4 on antennas and test sites for radiated disturbance measurements is relevant to:
- Testing authorities of radiated emission tests
- Manufacturers of radio disturbance and immunity measuring apparatus
- Manufacturers of wireless devices
- Electromagnetic engineers
Why should you use BS EN 55016‑1‑4- Antennas and test sites for radiated disturbance measurements?
An antenna is a part of a transmitting or receiving system that is designed to radiate or to receive electromagnetic waves in a specified way.
BS EN 55016‑1‑4 assists the user with the calibration test site which is an accessible area test site with metallic ground plane and tightly specified site attenuation performance in horizontal and vertical E-field (electric field) polarization. BS EN 55016‑1‑4 also assists with the common-mode absorption device which is a device that is applied on cables leaving the test volume in radiated emission measurements to reduce the compliance uncertainty. BS EN 55016‑1‑4 provides guidance on several types of test sites, test methods, and antennas. Antennas of the type that are used for radiated emission measurements are calibrated, which are used to measure the field strength, considering their radiation patterns and mutual coupling with their surroundings.
Overall, BS EN 55016‑1‑4 is useful as it describes a set of site attenuation measurement results for both vertical and horizontal polarizations using a pair of antennas separated by a defined distance at an ideal open-area test site, with one antenna at a specified fixed height above the ground plane, and the other antenna scanned over a specified height range.
