980 DP 1.4 Video Generator / Analyzer - User Guide
4 HDCP 2.2 Tests
This chapter describes how to use the 980 DisplayPort Video Generator / Analyzer module to test your DisplayPort
1.2 source, sink or repeater for proper HDCP 2.2 authentication. The HDCP 2.2 functional tests are optional
features and require the purchase of a license to run.
The module's DisplayPort 1.2 Tx port emulates a DisplayPort 1.2 source device with HDCP 2.2 capabilities. The
module's DisplayPort Rx port emulates either a DisplayPort 1.2 sink device with HDCP 2.2 capabilities or a
repeater device to test a source against an HDCP 2.2 repeater functionality.
The solutions enable you to quickly verify the HDCP authentication function of your HDCP 2.2-capable DisplayPort
1.2 device. Functional testing early in the development cycle is important for assessing and ensuring basic
functionality. You can view a summary of the authentication status at a glance from the dialog boxes and from the
Real Time status bar at the top of the 980 GUI window.
Whether testing a source, sink or repeater you can view the HDCP 2.2 authentication transactions in real time
using the Auxiliary Channel Analyzer (ACA) utility. You can save the ACA trace records and disseminate them to
subject matter experts for further analysis.

Running an HDCP 2.2 source test
The procedures below describe how to run the HDCP 2.2 authentication on a DisplayPort source device.
To run the HDCP 2.2 authentication test on a source:
1. Connect the DP source device to the DP module's Rx Analyzer port as shown below.
Note the second PC shown is used for the external 980 GUI Manager application. In this case you will use the
embedded 980 GUI Manager application on the 980 Test Platform.
2. Enable HDCP 2.2 on the source device under test. Note that you can either enable HDCP 2.2 prior to enabling
HDCP 2.2 on the 980 Video Generator / Analyzer module's Rx card or you can enable HDCP on the source
after you enable HDCP on the DP module.
3. Touch select the DP RX icon on the Card Control page of the Apps panel on the embedded 980 GUI
Manager (see below).
