802BT/802R Video Test Generator User Guide 157
Testing 8-channel HDMI audio output from internal source
To support testing of HDMI audio, the 802 generator provides 8-channel LPCM audio
(using an internally-generated sinewave) at the highest audio sampling rate (192 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 8-channel 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.
