802BT/802R Video Test Generator User Guide 159
To test an HDMI display using HDMI audio from an external source:
1. Connect an HDMI display to the Tx connector on the generator.
2. Connect the external audio source to the AV connector on the generator using the
RCA-to-VGA cable (part 30-00148) provided with the generator, as shown below:
3. If necessary, set up the generator for HDMI output.
•SeeSetting up the generator for HDMI operation” on page 147 for steps on setting
up the generator for HDMI operation.
4. Using the Format knob, select an appropriate format for the connected HDMI display.
5. Using the Image knob, select any desired image.
6. Using a terminal emulator, establish a terminal connection with the generator.
7. Configure the generator to use an external audio source by entering the following
command:
SDMG 2
FMTU
8. Set the sample frequency to match the frequency of the external source by entering the
following command:
ARAT 44.1E3 (example only)
Alternatively configure the generator to detect the audio sampling rate from the channel
header of the incoming digital audio.
ARAT 0.0
Note: The default frequency is 48 kHz (which is used by DVD players). However, if the
external source is an audio CD played on a DVD player, the player will output S/PDIF
with a sampling rate of 44.1 KHz (not 48 KHz). In this case, set the sampling frequency
to 44.1 kHz (or reload the format, which will detect the sampling frequency
automatically).
9. Turn on the external audio source.
The external audio signal will be encoded into the HDMI signal.
Note: The generator cannot independently control external source channels. You must
use the device generating the audio signal to control the channels.
