Unigraf DPR-100 or UCD-400
The Unigraf DPR-100 DisplayPort Reference Sink or UCD-400 DP 1.4a – HBR3 8K Generator &
Analyzer act as a DP AUX channel controller that connects between the Oscilloscope and the
DUT to allow for DPCD-based automated compliance testing. The Oscilloscope passes the
requested parameters over USB to the DPR-100 or UCD-400, which sends the parameters to
the Orin DP driver through DPCD commands over the DP AUX bus by the test fixture.
Refer to the test equipment documentation and dealer for more information.
Software
Only compliance test software should be used to guarantee an accurate result for compliance.
The NVIDIA Orin DisplayPort driver supports AUX channel automation with the Unigraf DPR
and UCD-400 to help make testing hands free.
Only compliance test software should be used to guarantee an accurate result for compliance.
Debug tools to access the Orin register space are necessary to fine-tune the settings.
Contact the test equipment dealer directly for more information.
Method for Tuning
There are several settings in the DisplayPort PHY to tune the output to meet the specifications
in the
DP Compliance Test Specification
(CTS). The subsequent sections in this chapter
