APx585 with HDMIHOME/PRODUCTS/APx SERIES/APx585 WITH HDMI
The APx is capable of taking 14 measurements in as fast as 7 seconds, automatically generating a report of results and saving all test settings in a single, sharable project file. Real-time signal monitors include residual THD+N in oscilloscope view and a one million point FFT.
With the APx HDMI option, engineers can now use the same tools to measure HDMI audio quality and audio format compatibility on devices such as surround sound receivers, set-top boxes, HD TVs, and DVD & Blu-ray Disc™ players.
The APx HDMI option provides connections for source and sink devices as well as an auxiliary video input and a monitor output. On the input (HDMI Sink) the APx will accept an HDMI signal and analyze the audio content. All standard audio measurements are available including level, SNR, distortion, phase, crosstalk, group delay and others.
Verifying Dolby & dts encoded audio
In addition to generating linear / PCM audio streams, APx can stream lossless formats (such dts-HD Master Audio™) and compressed formats (such as Dolby Digital™ and dts Digital Surround™) from pre-encoded audio test files.
This feature makes it easy to troubleshoot component compatibility and downsampling / downmixing / transcoding issues.
Streaming of .wav, .ac3, .dts, and .cpt over the SPDIF, TOSLINK, and AES/EBU digital outputs is also supported.
Support for Blu-ray Disc players
Because Blu-ray and other disc players cannot accept an incoming audio stream, test signals must be played from disc. Every HDMI APx includes a Blu-ray Disc with high-resolution versions of a wide selection of audio test signals in the same formats as the APx generator.
Video and third party support
The APx HDMI option has a basic video generator. The user can generate a single color video test signal and control the resolution (up to 1080p), the color of the image, and the color depth (including deep color).
Use of third party video pattern generators is supported by the “Pass External Video Through” option. When an external video signal is provided, APx combines it with the audio stream from the APx’s generator and outputs a single audio/video stream.
The system also forwards E-EDID and CEC data transparently between the device under test and any device connected to AUX IN.
The APx itself does not analyze video; however, all signals delivered to the sink are mirrored to the AUX OUT monitor connector. This allows the user to send the video signal to an external video analyzer or monitor the signal on a display.
