This document presents the test setup photographs for radiated emissions testing conducted by Bay Area Compliance Laboratories Corp. (Shenzhen). The photographs illustrate the setup used to evaluate the electromagnetic compatibility of the devices under test. The models tested include RS485-NB, RS485-NS, DDS04-NB, and DDS04-NS. The testing was performed in accordance with relevant standards to ensure compliance with regulatory requirements.
The photographs showcase the positioning of the equipment within the shielded chamber, the antenna configurations used for different frequency ranges (below 30MHz, below 1 GHz, 1-18 GHz, and 18-25 GHz), and the overall test environment. These images provide a visual record of the testing process and serve as supporting documentation for the test report (Report No.: 2401Z66847E-RF). The setups are designed to accurately measure radiated emissions and assess the potential for interference from the devices.
