980 Operational Modes

The 980 can be operated in one of two operational modes:
Capture and Post Analysis – The Capture and Post Analysis mode is the typical mode of operation and the

mode used to analyze HDMI data. It is also the mode used for running the HDMI Source Compliance Tests.
The Capture and Post Analysis mode is available both through the built-in touch display GUI and the external
980 Manager GUI.

Real Time Monitoring - The Real Time Monitoring mode is used to provide at-a-glance insights into the
incoming video. You can view the incoming video even when the video encrypted with HDCP content
protection. You can also view the incoming HDMI video/audio metadata and DDC transactions. The Real Time
mode enables you to collect data in real time and compare incoming data over time to ―reference‖ data
collected earlier. The Real Time mode is available only through the built-in touch display GUI.

980 Analysis Configurations

The 980 can be setup for analysis in one of three configurations:
 Sink emulation – In the sink emulation monitoring configuration the 980 HDMI Rx port is connected directly to
the source device under test. The 980 is emulating an HDMI sink device. The sink emulation mode is the
typical mode of operation. You can monitor the HDMI transactions between the source device under test and
the 980 Rx port. All of the data types described in this manual can be monitored in the sink emulation mode
unless noted otherwise.
 Pass-Through Monitor –In the pass-through monitoring configuration the 980 HDMI Rx port is connected to
the source device under test and the 980 HDMI Tx port is connected to a sink device. The pass-through mode
enables you to monitor the HDMI traffic passively between an HDMI source and an HDMI sink device. If the
video content from the source device is unencrypted you will be able to see all the data through the capture
period. If the video content from the source device is encrypted with HDCP you will be able to see all the data
and the incoming video up until encryption is enabled. Once encryption is enabled, you will be able to see the
DDC (or MHL C-Bus) and CEC transactions and the timing parameters but not the HDMI data islands. The
HDCP transactions that you will see are the transactions that occur between the source and the sink device. In
pass-through mode the 980 passes through the EDID of the display to the source device under test. The 980
does not function as an HDCP repeater.

Encrypted Link Analyzer - In the Encrypted Link Analyzer configuration the 980 HDMI Rx port is connected to
the source device under test and the 980 HDMI Tx port is connected to a sink device. The Encrypted Link
Analyzer configuration enables you to monitor and analyze HDCP encrypted protocol data transmitted
between an HDMI source device and sink device. Note that you will not be able to view the HDCP transactions
between the source and the sink. With the Encrypted Link Analyzer you can investigate HDMI interoperability
while the content is encrypted by viewing the metadata in real time and observing the behavior of the
downstream sink device. The Encrypted Link Analyzer enables you to capture the encrypted metadata and
store it for detailed analysis. With the capture operation, you can monitor the downstream HDMI sink device for
particular symptoms and then initiate a capture when the symptoms exhibit themselves. This ensures that the
relevant data—data related to interoperability—is captured.
