This document provides a visual overview of the test setup used for evaluating radiated emissions. The images depict the arrangement of equipment and the environment used for conducting these tests. Radiated emissions testing is a crucial aspect of ensuring that electronic devices comply with regulatory standards and do not emit excessive electromagnetic interference.
The document includes photos of the setup for both radiated band edge emission and radiated spurious emission testing. The band edge emission tests focus on emissions near the boundaries of the device's operating frequency bands, while the spurious emission tests cover a broader range of frequencies to identify any unwanted emissions. These tests are performed in a controlled environment, typically an anechoic chamber, to minimize reflections and ensure accurate measurements.
The test setup includes the device under test (DUT), antennas, measurement equipment, and any necessary support equipment. The DUT is positioned on a turntable, and the antennas are used to detect radiated emissions at various frequencies and polarizations. The measurement equipment records the detected emissions, which are then analyzed to determine compliance with applicable standards.
