2.4.2 Pass-Through Monitor
The pass-through mode enables you to monitor the HDMI traffic passively between an HDMI source and an HDMI
sink device. In the pass-through monitoring configuration the 980 HDMI Protocol Analyzer HDMI Rx port is
connected to the source device under test and the 980 HDMI Protocol Analyzer HDMI Tx port is connected to a
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 HDMI DDC transactions and CEC messages and the timing parameters but not the HDMI metadata and
protocol data. The HDCP transactions that you will see are the transactions that occur between the source and the
sink device.
2.4.3 Encrypted Link Analyzer
In the Encrypted Link Analyzer configuration the 980 HDMI Protocol Analyzer HDMI Rx port is connected to the
source device under test and the 980 HDMI Protocol Analyzer 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.
