More InfoLess Info
The high-definition multimedia interface (HDMI) has fully captured the consumer market. The interface transmits audio and video data and status and control data on a single cable. The HDMI ports of all consumer electronics equipment must be tested. Measurements are performed during development, quality assurance and end-of-line production testing. However, measurements are also needed during the development and testing of HDMI integrated circuits. The R&S UPP audio analyzer with integrated HDMI option covers all these requirements. In this configuration, the instrument offers the HDMI, S/P DIF and I2S digital interfaces, as well as analog interfaces. This makes it possible to perform measurements on all HDMI devices with any combination of interfaces.
