GRL-DP21-SINK-AN User Guide & MOI Rev. 2.5

1Introduction

This User Guide & MOI describes the procedures to perform DisplayPort 2.1 Sink (or Receiver)

calibration and tests of the VESA DisplayPort Logo Compliance Program using the Anritsu

MP1900A BERT and High Performance Real-Time Oscilloscopes in conformance with the

DisplayPort PHY 2.1 Compliance Test Specification (CTS). Sink tests are required to qualify a Sink

product or silicon building block for Logo certification and listing on the DP Integrators List.

This User Guide & MOI explains how to set up and use the GRL-DP21-SINK-AN software to

automate receiver calibration and compliance testing for DisplayPort 2.1 Sink conformance. The

GRL-DP21-SINK-AN software is used with the Anritsu MP1900A BERT for testing DisplayPort

receivers per the Jitter Tolerance requirements of the DisplayPort PHY CTS and DisplayPort over

USB Type-C® CTS respectively.

The GRL-DP21-SINK-AN software automates stressed signal calibration and jitter tolerance testing

at the following DisplayPort data rates‒UHBR 10 (10.0 Gbit/s per lane), UHBR 13.5 (13.5 Gbit/s per

lane) & UHBR 20 (20.0 Gbit/s per lane) and supports USB Type-C and standard DisplayPort sink

device-under-tests (DUT’s). For link training, compliance, and margin testing through DPCD

registers, the software provides automation control using a compatible DisplayPort AUX

controller.

The following are the main topics covered by this User Guide & MOI:

1. Equipment required for calibration and testing.

2. GRL-DP21-SINK-AN software setup for calibration and test automation.

3. Manual DisplayPort PHY CTS Sink calibration and test methodology.

3Installing and Setting Up GRL-DP21-SINK-AN Software

This section provides the procedure for installing, configuring and verifying the operation of the

GRL-DP21-SINK-AN software. It also helps you familiarize yourself with the basic operation of the

software.

The software installer automatically creates shortcuts in the Desktop and Start Menu.

To open the software application, follow the procedure in the following section.

3.1 Download and Set Up GRL-DP21-SINK-AN Software

Install, launch and set up the GRL-DP21-SINK-AN software on a PC or an oscilloscope (where GRL-

DP21-SINK-AN is referred to as ‘Controller PC’ or ‘Scope’ respectively in this MOI & User Guide):

1. Install VISA (Virtual Instrument Software Architecture) on to the PC/Scope where GRL-DP21-

SINK-AN is to be used (see Section 2.1).

2. Download the GRL-DP21-SINK-AN ZIP file package from the Granite River Labs support site.

3. The ZIP file contains:

a) DPSink21_ANPatternFilesInstallationxxxxxxxxxSetup –Run this on the Anritsu

MP1900A BERT to install the DisplayPort 2.1 test pattern setup files. This will place the

DisplayPort Configuration and Pattern files on the MP1900A BERT in the

‘C:\Configurations\Anritsu DisplayPort Sink Test 2.1’directory hierarchy.

b) DPSinkTest21_ANApplicationxxxxxxxxxSetup –Run this on the Controller PC or

Oscilloscope to install the GRL-DP21-SINK-AN application. This application will create the

‘C:\GRL\Rx Test Solution\Applications\DPSinkTest20_AN’directory hierarchy.

c) DPSinkTest21_ANScopeSetupFilesInstallationxxxxxxxxxSetup –Run this on the

Oscilloscope to install the Infiniium setup files. This will place the DisplayPort Setup and

Filter folders in the ‘C:\GRL\Agilent\Setup\Anritsu DisplayPort Sink Test 2.1’of the Keysight

Scope or C:\TekApplications\DPOJET of the Tektronix Scope directory hierarchy.

3.1.1 On the Anritsu MP1900A BERT

1. Launch the Signal Quality Analyzer-R Control Software.

2. Select the “Expert BERT” button to turn on the Miscellaneous System. This will allow you to

remotely control the MP1900A BERT.

3. Note the IP Address as it will be used to connect the MP1900A BERT with the GRL-DP21-SINK-

AN software.

3.1.2 On the PC Used for GRL Framework Installation

1. Open the GRL folder from the Windows Start menu. Click on GRL –Automated Test Solutions

within the GRL folder to launch the GRL software framework.

FIGURE 2. SELECT AND LAUNCH GRL FRAMEWORK

2. From the Application →Rx Test Solution drop-down menu, select Anritsu DisplayPort Sink

Test 2.1 to start the application. If the selection is grayed out, it means that your license has

expired.

3. To enable license, go to License→License Details.

FIGURE 4. SEE LICENSE DETAILS

a) Check the license status for the installed application.

FIGURE 5. CHECK LICENSE FOR INSTALLED APPLICATION

4. Activate License:

a) If you have an Activation Key, please enter in the box provided and select Activate.

b) If you do not have an Activation Key, select Close to use a demo version of the software

over a free 10-day trial period.

Note: Once the 10-day trial period ends, you will need to request an Activation Key to continue using

the software on the same computer or oscilloscope. The demo software is also limited in its

graniteriverlabs.com

GRL-DP21-SINK-AN User Guide & MOI Rev. 2.5

capability, in that it will only calibrate the maximum frequency for each data rate. Thus, the demo

version cannot be used to fully calibrate and test a device. For Demo and Beta Customer License

Keys, please request an Activation Key by contacting [email protected].

5. Select the Equipment Setup icon on the DisplayPort Sink Test 2.1 Application menu.

4. Connect the Anritsu MP1900A BERT via LAN to the GRL automation control enabled Scope or

PC. Enter the MP1900A IP address and Port number to match what is shown in the MP1900A

Remote Client window in Section 3.1.1. For example, the BERT can be connected using a

connection string in the following format: “TCPIP0::192.168.0.14::5001::SOCKET” or

“192.168.0.14:5001”. Note the IP address listed is only example and should be changed

according to the actual network connection being used.

6. On the Scope or controller PC, obtain the network addresses for all the connected instruments

from the device settings. Note these addresses as they will be used to connect the instruments

to the GRL automation software.

(Note: The Scope IP address can be obtained, if not known, by typing CMD → IPCONFIG on the

Scope and observe the IP address listed. If the GRL software is installed on the Tektronix Scope,

ensure the Scope is connected via GPIB and type in the GPIB network address, for example

“GPIB8::1::INSTR”.) If the GRL software is installed on the PC to control the Scope, type in the

Scope IP address, for example “TCPIP0::192.168.0.110::inst0::INSTR”. Note to omit the Port

number from the address.)

7. Then select the “lightning” button ( ) for each connected instrument.

The “lightning” button should turn green ( ) once the GRL software has successfully

established connection with each instrument.

Recommended procedure:

Step 1: When calibrating, select the desired conditions and perform the calibration tests.

Step 2: When ready for testing, re-select the desired test conditions. For example, if required to

test only one Lane at one SJ Frequency for the UHBR10 Data Rate, then select the appropriate

conditions for testing.

a) Lane tab: Select the desired Lanes for testing. [Note: This is only applicable for DUT compliance

test and NOT for calibration.]

b) Test Point tab: Select the test points for calibration and testing. [Note: TP1 calibration (Total

Jitter & Eye Height) must be performed first prior to TP3_EQ calibration (Optimized EQ Lookup,

Eye Height & Eye Width).]

c) Data Rate tab: Select the desired data rates for calibration or testing:

•UHBR 10 (10.0 Gbit/s per lane)

•UHBR 13.5 (13.5 Gbit/s per lane)

•UHBR 20 (20.0 Gbit/s per lane)

3.2.3 Set Up AUX Controller for DUT Test Automation

Select from the menu to access the Setup Configuration page.

Select to use a supported AUX Controller in the DUT test setup or select ‘None’ if not using an AUX

Controller. Then enter the COM port number of the connected AUX controller.

3.3 Select Calibration/Test

Go to the Select Tests page on the left of the screen to select the available calibration or tests to

be performed. Select the check box(s) of the desired calibration/test.

Initially, when starting for the first time or changing anything in the setup, it is suggested to run

Calibration first. If the calibration is not completed, the Sink Tests will show an error message.

FIGURE 13.CALIBRATION SELECTION

Select the calibration groups to perform calibration for all DisplayPort Sink parameters. Note that

while the user can select individual calibration parameters, it is possible that a particular

calibration may require the previous calibration to be completed before it can proceed. Thus, it is

advisable to complete all previous calibration before going on to the next calibration.
