Testing HDMI audio
This section provides steps on how to test handling of audio packets by an HDMI display.
Testing can be performed using audio originating from both internal (generator) and
external sources. The generator supports both 2-channel SPDIF audio from internal
source and external source and up to 8-channel audio from an internal audio source.
There are seperate sets of images for testing 2-channel SPDIF audio and 8-channel
audio.
Testing 2-channel HDMI audio output from internal SPDIF source
To support testing of HDMI audio, the 802 generator provides two-channel LPCM audio
(using an internally-generated sinewave) at the highest audio sampling rate (48 kHz).
Multiple scenarios are provided that allow you to test one or both audio channels at
different amplitudes and frequencies, as well as test using the different supported
sampling rates.
The following table lists the images used to perform HDMI audio testing using an internal
audio source.
To test an HDMI display using HDMI audio from the generator:
1. Connect an HDMI display to the Tx connector on the generator.
2. If necessary, set up the generator for HDMI output.
•
See “
Setting up the generator for HDMI operation
” on page 147 for steps on setting
up the generator for HDMI operation.
3. Using the
Format
knob, select either the DMT0660 or 480i2x29 format.
