Description
The APx HDMI option (HDMI+ARC) for the APx555, APx525 and APx585 allows engineers to measure HDMI audio quality and audio format compatibility on devices such as surround sound receivers, set-top boxes, HD TVs, smartphones and tablets, and DVD or Blu-ray Disc™ players. Connections are provided for source and sink devices, as well as additional HDMI connections for auxiliary video input and a monitor output. An additional set of HDMI connectors (also utilized for AUX In and Monitor Out) are provided for Audio Return Channel transmit and receive. In addition to full audio and metadata analysis capabilities, APx500 can send and receive CEC commands, allowing observation and troubleshooting of ARC connection negotiations. The regular HDMI connectors may also be used simultaneously, making it possible to send a test signal to a device over HDMI and to receive it back over ARC for analysis.
