Audio-Video and IT Test Solutions

LISUN’s audio – video information communication testing solutions are designed to meet the requirements of key international standards, providing professional support for testing the safety, electromagnetic compatibility (EMC), and performance of audio – video information communication equipment such as broadcast television devices, audio systems, and information technology equipment. Among these standards, CISPR 13:2021 focuses on the EMC requirements for sound and television broadcast receivers and associated equipment, specifying limits and test methods for radiated and conducted emissions. CISPR 22:2018 is applicable to information technology equipment, regulating their electromagnetic emission levels to avoid interference with other devices. IEC 60065:2021 covers safety requirements for audio, video, and similar electronic apparatus, ensuring protection against electric shock, fire, and other hazards. Additionally, FCC Part 15 and EN 55032 also set important norms for EMC in related equipment, which are widely recognized and adopted in international markets.​

LISUN’s audio – video information communication testing solutions cover all key test items specified in the above standards, equipped with a full set of professional testing equipment. This enables comprehensive testing including EMC tests such as radiated emission (electric field and magnetic field), conducted emission, electrostatic discharge immunity, electrical fast transient/burst immunity, surge immunity, and radiated radio frequency electromagnetic field immunity. It also supports electrical safety tests like insulation resistance and dielectric strength testing, as well as audio – video performance tests including frequency response, signal – to – noise ratio, and distortion measurement. Moreover, tests for interface compatibility and voltage fluctuation and flicker can be carried out. Through one – stop testing support, we help manufacturers and laboratories ensure that audio – video information communication equipment comply with international standards, guaranteeing their stable operation, reliable performance, and good communication quality in practical applications.
