Setup for Radiated and Conducted Emission Tests
Document Reference: FCCSZ2024-0023-EUT
Conducted Emission Test Setup
The setup for conducted emission testing shows the Equipment Under Test (EUT) positioned on a wooden table within a controlled environment, likely an anechoic or shielded room. Cables are connected to the EUT, indicating a connection to power and potentially data interfaces. This configuration is standard for measuring electromagnetic interference that is conducted back onto the power supply lines.
Radiated Emission Test Setup Below 1GHz
This section details the setup for radiated emission testing below 1 GHz. The EUT is placed on a turntable, a common feature in anechoic chambers used for electromagnetic compatibility (EMC) testing. The chamber walls are visibly lined with RF absorbing materials, often forming a distinctive grid pattern, to prevent reflections. Antennas are positioned to capture emissions radiated from the EUT.
Radiated Emission Test Setup (1GHz - 18GHz)
The setup for radiated emission testing between 1 GHz and 18 GHz is depicted. Similar to the lower frequency test, the EUT is situated on a turntable within an anechoic chamber. The specific arrangement and potentially the type of antennas used are optimized for capturing emissions within this higher frequency range.
Radiated Emission Test Setup (18GHz - 40GHz)
This image illustrates the test setup for radiated emissions in the frequency range of 18 GHz to 40 GHz. The EUT is again positioned on a turntable inside the anechoic chamber. This setup is designed to measure emissions across a very high frequency spectrum, requiring specialized equipment and configurations.
