TekExpress® DisplayPort Automated Solution Application Help 9
Welcome
Welcome
The Tektronix TekExpress DisplayPort software supports CTS 1.2 and CTS 1.4. The software uses Tektronix DisplayPort AUX controller
(DP-AUX for standard DP 1.2 DUT) and Unigraf DPR-100 to automate DisplayPort physical layer source compliance tests for Standard
and Type-C connectors. The DP-AUX/ DPR-100 puts the DUT in different test modes and eliminates the need for user intervention during
testing. For Alpine Ridge DUTs, the software automates the TenLira scripts to put the DUT into different test modes.
Tektronix provides various tools such as DPOJET (Jitter and Eye Analysis tool), SDLA (Serial Data Link Layer Analysis), and DisplayPort
essential (DisplayPort measurement library) to perform the characterization/debug of the silicon, and TekExpress DisplayPort application to
perform the compliance tests.

• One-button MHT report format saves time.
• Complete Solution: Complete compliance solution with an elaborate test fixture and support for SMA probing provides a cost-effective
way to perform compliance testing.
• Customize the setup:
• Modify the test setup according to the DUT configuration.
• Run tests using different record lengths.
• Run test measurements using more than one signal.
• Detailed test reporting:
• Provides a Pass/Fail summary table.

Before you run tests for the first time, do the following:
1. Understand where your test files are stored on the instrument.
After you install and launch TekExpress DisplayPort, it creates the following folders on the oscilloscope:
• Windows 10: C:\Program Files\Tektronix\TekExpress\ TekExpress DisplayPortTx
• \My Documents\My TekExpress\ DisplayPort
• \My Documents\My TekExpress\DisplayPort\ Untitled Session
Every time you launch TekExpress DisplayPort, an Untitled Session folder is created in the DisplayPort folder. The
Untitled Session folder is automatically deleted when you exit the DisplayPort application.
CAUTION:
Do not modify any of the session files or folders because this may result in lost data or corrupted session files. Each session
has multiple files associated with it. When you save a session, a .T
the associated files, is created on the oscilloscope X: drive.
2. Map the shared My TekExpress folder as X: (X drive) on all the instruments used in test setups running Microsoft Windows Operating
System.
The My TekExpress folder has the share name format <domain><user ID>My TekExpress. Or, if the instrument is not connected
to a domain, then the share name format is <instrument name><user ID> My TekExpress. This shared folder is
used to save the waveform files and is used during other file transfer operations.
Note: If the X: drive is mapped to any other shared folder
disconnect the X: drive manually.
3. Make sure that the My TekExpress folder has read and write access, and that the contents are not set to be encrypted:
a. Right-click the folder and select Properties.
