This document showcases the test setup used to evaluate the radiated emissions of the DAC+ device, specifically focusing on frequencies below 1 GHz. The setup adheres to industry standards and FCC regulations to ensure accurate and reliable measurements. The image provides a visual representation of the device under test (DUT) positioned within an anechoic chamber. This chamber is designed to minimize reflections and external interference, creating a controlled environment for emissions testing.
The test setup includes the DUT, a turntable to rotate the device, and an antenna to receive radiated signals. The antenna is connected to a spectrum analyzer or receiver, which measures the amplitude and frequency of the emissions. The data collected during the test is then analyzed to determine whether the device complies with the specified emission limits. This rigorous testing process is crucial for obtaining FCC certification and ensuring that the device does not cause harmful interference to other electronic equipment.
