Source PHY Tests (CTS1.2b Section 3) 1. Introduction This MOI (Method of Implementation) provides the test procedures for testing DisplayPort Source to the DP 1.2b Compliance Test Specification (CTS). The purpose of the document is to provide the approved test equipment, test connections and setup, and procedures for the DP1.2 compliance program. Review and approval of compliance test procedures for DisplayPort is the responsibility of the VESA Test Implementation Subgroup. The test procedures in this document are only the Normative (or required) tests in the DP 1.2b CTS. For informational tests, refer to the test equipment vendor s documentation. 2. Test Pre- test Procedures Prior to making any measurements, the following steps must be taken to assure accurate measurements: Allow a minimum of 20 minutes warm-up time for oscilloscope. Run oscilloscope calibration routines. Agilent Infiniium oscilloscope calibrations are valid over a specific temperature range even after a power cycle so the oscilloscope does not have to be recalibrated before every test device or every day. If using probes, perform the probe calibration defined for the specific probes being used. Make sure you use a torque wrench to make all SMA connections. 3. PHY CTS 1.2b Source Testing Overview This section describes the procedure for testing the DisplayPort Source electrical parameters. This testing is required for all ports on a device under test. The DP electrical parameters are as specified by Section 3 of the PHY CTS 1.2b. The CTS is available to VESA members at www.vesa.org. Agilent offers probing and automation software used for testing DisplayPort, which is used for this procedure. This document covers the following PHY CTS 1.2b tests: 3.1. EYE Diagram Testing 3.2. Non Pre- Emphasis Level Verification Testing 3.3. Pre- Emphasis Level Verification and Maximum Differential Pk- Pk Output Voltage 3.4. Inter- Pair Skew Test 3.11. Non ISI Jitter 3.12. Total Jitter (TJ) and Random Jitter (RJ/DJ) 3.14. Main Link Frequency 3.15. Spread Spectrum Modulation Frequency (if DUT supports SSC) 3.16. Spread Spectrum Modulation Deviation (if DUT supports SSC) 3.18. Dual- mode TMDS Clock (if DUT supports Dual- mode) 3.19. Dual- mode EYE Diagram (if DUT supports Dual- mode) DisplayPort Test Implementation Group 7 Agilent 90000A/X/Q Series Source MOI Draft2

Connecting to the DUT for testing (Referring to Figure 8) 1. Plug HPD Connection from DP Test Adapter (Wilder as an example) into the AUX Adapter board. 2. Connect SMA Cables from the AUX connections on the Test Adaptor to the AUX connections on the AUX Adapter board. 3. Attach USB Cables from the AUX adaptor board to the DP AUX Controller. 4. Connect the AUX Adapter board to the DP AUX Controller using a standard DP Cable. 5. Connect the differential SMA pairs on the DP test adapter to the Differential Probe Heads using SMA cables as in the following table: DisplayPort Test Implementation Group 13 Agilent 90000A/X/Q Series Source MOI Draft2

On the oscilloscope, select the Setup > Probe menu. Figure 9: Probe Setup Dialog Panel 7. For each channel, verify that the channel is reported as connected to the proper probe amplifier (1168A in this example). If this is not the case, then check the physical connection of the probe to the appropriate oscilloscope channel. 8. In the Probe Head pull-down, verify that the proper probe head (N5380 in this example) is selected. If not, then click on Add Head The Add/Edit User Defined Head panel appears. In the pull-down menu, select the proper probe head that is attached to the differential amplifier. In this example it would be N5380A:Df SMA.

9. Ensure the DUT is powered. Figure 10: Setup Probes Add User Defined Head Dialog 9. Running the DisplayPort Compliance Tests The following is the recommended test flow for a 4 lane Source that supports all Swing and Pre- Emphasis Levels. The testing is broken up into the following two sub-sections. 1. RBR/HBR/HBR2 Measurements this section takes advantage of the DPCD Control over the AUX channel to capture all waveforms and performs all the required tests for RBR and HBR. It also describes the test procedure if the DUT does not support automation. 2. Dual Mode Measurements this section describes how to put the DUT in a TMDS signaling mode at the proper resolution in order to make the Dual Mode (DP++) compliance measurements. 9.1. RBR/HBR/HBR2 Measurements This section takes advantage of the DPCD Control over the AUX channel to capture all waveforms and performs all the required tests for RBR and HBR. It is highly desirable to perform these tests with automation due to the number of test conditions that need to be performed. Full automation reduces an engineer s time to execute and removes human error from the DUT setup during testing. However, not all sources support full automation. Thus, both automated and non-automated procedures are outlined below. 9.1.1. RBR/HBR/HBR2 Measurements if the DUT supports Automation If using full automation, execute the RBR/HBR tests as follows: DisplayPort Test Implementation Group 15 Agilent 90000A/X/Q Series Source MOI Draft2

9.2. Dual Mode Measurements (if the DUT supports Dual- Mode) This section describes the procedure for running Dual Mode Display Port (DP++) tests as called out in Sections 3.18 and 3.19 of the DP1.2b CTS. This procedure is implemented using the same setup as in Figure8 with a fixture that is configured for Dual Mode testing. 9.2.1. Connecting to the DUT for testing (Referring to Figure 8) In this example, the Wilder AUX adapter needs to be changed to the correct jumper settings for Dual Mode testing. The following figure shows the correct jumper settings. Wilder AUX Controller Board Dual Mode Test Jumper Location Figure 31: Wilder AUX Control Board used for Dual Mode Testing 9.2.2. Dual Mode (D++) Test Procedure The following procedure is to be used for Dual Mode testing. 1. If not already running, start the U7232B DisplayPort Test App in the Infiniium GUI.
