In-Situ Radiated Emission Testing of Large Systems Installations
When it comes to in-situ radiated emission measurements, the combination of near- and far-field measurements is often the best approach. Near-field measurements can help identify the sources of emissions, including individual modules or components and their frequency and amplitude characteristics. This information can then be used for far-field measurements. Far-field measurements involve using antennas to measure the radiated noise, with full‑size antennas recommended for measurements between 30 and 200 MHz.
