Introduction：
CDN S19 HDMI is a coupling decoupling network device for HDMI connectors for high definition video signals from Schwarzbeck, Germany, which is authorized to be sold and quoted as a service by EUTTEST Shenzhen. The device meets the requirements of IEC 61000-4-6, Figure D.1, and can be used for conducted immunity testing of products with 19-pin HDMI HD video cable connectors.
Product under test:
High Definition Multimedia Interface (HDMI) is a fully digital video and sound transmission interface that can send uncompressed audio and video signals, HDMI can be used in TV set-top boxes, DVD players, personal computers, televisions, gaming consoles, integrated amplifiers, digital stereos and televisions, etc. The standard Type A HDMI connector has 19 pins, and a Type B connector has been defined to support higher resolution, but no manufacturer has yet adopted the Type B connector. The standard Type A HDMI connector has 19 pins, and another Type B connector has been defined to support higher resolution, but no manufacturer uses Type B. The Type B connector has 29 pins, which allows it to send an extended video channel to cope with future high image quality requirements, such as WQSXGA (3200×2048). Therefore, this device can only test type A HDMI connectors. The device supports a maximum of 100V AC or 150V DC input from the DUT and is rated at 0.25A.
If you want to test For conducted immunity of the VGA port, please purchase the CDN S15 VGA connector coupling decoupling network.The
