2. Select the Link Mode item from the pull-down menu on the built-in front panel as shown below.
A pop out menu will appear enabling you to select the desired mode using the check boxes provided:
 HDCP Enabled – In the Enabled mode, the 980 HDMI Protocol Analyzer sink emulator will respond to
HDCP authentication from a source device under test. When disabled the 980 sink emulator will not
respond to an HDCP authentication request.
 BSTATUS – This check box enables you to toggle between the 980 HDMI Protocol Analyzer sink emulator
responding to a source HDCP authentication by indicating in its BSTATUS register that it is or is DVI in
HDMI mode.
 Set BCAPS – This check box opens up a dialog box enabling you to configure the bits of the BCAPS
register. The dialog box is shown below. You can set the bits by clicking on that bit. Clicking on any one bit
will toggle the binary value. The hex value of the BCAPS register is shown in the field above the bit values
(80 in the example below).
9.3.6 Initiating a Capture
Typically in the Capture mode you will want to specify a manual capture when using the Encrypted Link Analyzer.
With the manual capture, you can monitor the downstream HDMI sink device for particular behavior or symptom to
a problem and then initiate a capture when the particular condition exhibits itself. This ensures that the relevant
data—data related to interoperability—is captured.
Use the procedures below to initiate a new capture.
1. (optional) If you are going to be taking some action on the device under test that will halt video, such as
unseating and reseating the HDMI cable, you will need to check the Video Check box in the Capture
Configuration section of the Capture Control dialog box.
