Mode on the 980 HDMI Protocol Analyzer Tx
port. Emulates an ARC Rx.
13.1 Test ARC on an HDMI source (ARC Rx)
The procedures below describe how to use the 980 to emulate an ARC Tx device (HDMI sink). The 980 can use
audio from its internal source or you can feed an external SPDIF source into the 980 HDMI Protocol Analyzer and
have the 980 HDMI Protocol Analyzer inject the SPDIF audio onto the Audio Return Channel on its HDMI Rx port.
The ability to emulate an ARC Tx device enables you to determine if your HDMI source device (typically an A/V
receiver) can properly handle an audio return channel stream. Refer to the diagram below for a depiction of the
general test setup.
To test the ARC handling by an HDMI source (ARC Rx):
1. Connect an HDMI 1.4a cable from the HDMI 1.4a A/V receiver to the 980 HDMI Protocol Analyzer Rx port.
2. Determine the HEAC mode for ARC that you wish to test with and then activate that mode by clicking on the
appropriate activation button. For example if you wish to test ARC in the Single Mode you would select the
appropriate button in the RX HEAC Control
– HEAC Mode subpanel as shown below.
3. Determine what SPDIF source you wish to use: 1) from the SPDIF source on the 980 HDMI Protocol Analyzer,
or 2) from an external SPDIF source. Select the appropriate activation button in the ARC Source subpanel.
