radiofrekvensmåler

A radiofrekvensmåler, often translated as radio frequency meter or RF meter, is an electronic instrument used to measure the intensity of radio frequency electromagnetic fields. These devices are essential for various applications, including telecommunications, broadcasting, and electromagnetic compatibility testing.

The principle of operation for most radiofrekvensmålere involves an antenna that captures the radio waves present in the environment. This captured energy is then converted into an electrical signal. The meter then processes this signal to quantify its strength, typically displayed in units such as milliwatts per square centimeter (mW/cm²) or volts per meter (V/m). Some meters can also measure the frequency of the detected radio waves.

Radiofrekvensmålere are used to ensure that radio frequency emissions from devices comply with regulatory limits designed to protect human health and prevent interference with other electronic equipment. They are also employed by engineers to troubleshoot and optimize radio communication systems. Different types of meters exist, varying in their frequency range, sensitivity, and measurement capabilities, catering to specific professional needs.
