DisplayPort and Embedded DisplayPort Tuning Guide
PRELIMINARY INFORMATION
Jetson AGX Orin Series Tuning and Compliance Guide DA-11040-001_v0.7 | 37
Abbreviation Definition
HBR High Bit Rate (2.7 Gbps)
HBR2 High Bit Rate 2 (5.4 Gbps)
HBR3 High Bit Rate 3 (8.1 Gbps)
Link Training Establishing a link between source and sink before normal operation
RBR Reduced Bit Rate (1.62 Gbps)
Sink Any type of receiver, such as a display or panel
SOR Serial Output Resource. Module naming referring to the DP and eDP block
Source Any type of transmitter, such as Orin
SSC Spread Spectrum Clock, will reduce EMI
Required Equipment
The following hardware and software are required:
Hardware
• DP Plug Test Fixture, corresponding to the plug type
• Oscilloscope and Probes
• Unigraf DPR-100 DisplayPort Reference Sink or UCD-400 DP 1.4a – HBR3 8K
Generator & Analyzer
Software
• DisplayPort Compliance Test Software
• NVIDIA Orin DisplayPort Driver for AUX channel automation
Test Fixtures
Test fixtures connect the probes to the outputs of the Serial Output Resource (SOR) of the
DUT. NVIDIA recommends that a native fixture be selected and that no adapters be used
between the DP connector and the DP test fixture, since adapters will heavily affect the signal
integrity.

WilderTech
VPrime
Keysight
Oscilloscope and Probes
The oscilloscope and probes are used to measure the signal electrically. The equipment must
be capable of accurately measuring the maximum bitrate supported by the DUT, up to 8.1
Gbps (HBR3).
