Full Automated DisplayPort Sink Device Compliance Testing

The BERTScope DP SINK CTS provides a complete physical layer testing solution for DisplayPort Sink devices. The system provides full coverage of the DisplayPort PHY Compliance Test Specification for Sink devices. It also offers the designer additional information beyond the compliance–PASS/FAIL result, with Fast Mode analysis, monitoring, and device control tools.

The BERTScope DP SINK CTS features include:

• Fully automated compliance testing with test report generation
• Automated lane switching
• Pre-calibrated stress levels to eliminate the need for pre-test calibration
• Everything necessary for testing — right out of the box

Full Aux Channel Control
The key component for implementing a Sink Device PHY test is the Aux Channel Controller. This device communicates with the device under test, reading the bit error counter at the proper times as required to determine the BER. The Aux Channel Controller in the BERTScope CP SINK CTS is the first design to be truly universal — compatible with any design of SINK Device.

The Aux Channel Controller also supports interruptible straight-through signal path of the four lanes to the Main link, facilitating access for compliance testing. Including both Sink and Source side connectors, the controller interface can access the lanes for compliance testing of the Source device as well.

Fully Automated Lane Selection
As the lanes adjacent to the one being tested are driven with a crosstalk signal, changing the tested lane during a compliance test is a labor-intensive task. The automated lane switch eliminates the need to manually move cables. The lane switch incorporates the ISI channels and other signal conditioning required for compliance test.

Full Performance Pattern Generator
The BERTScope DP SINK CTS includes a BSA12500B SPG Stressed Pattern Generator. It also can support a full BERTScope, for users who also need to perform Source testing. The pattern generator in these instruments provides the stressed stimulus, including Spread Spectrum Clocking (SSC), which fully meets the requirements of the Compliance Test Specification.

Pre-Calibrated Stress Levels
The BERTScope DP SINK CTS is shipped from the factory pre-calibrated to provide the correct stress levels for compliance testing to the DisplayPort PHY Compliance Test Specification. This eliminates the need to perform complicated, error prone stress calibration before testing. Simply connect the system as illustrated, power-up the instruments and DUT, and begin testing!

Integrated Test Automation Software
The DP SINK CTS includes compliance test automation software, which provides a control interface that is easy to configure and use. A full compliance test can be initiated with a single click, allowing unattended operation. For design characterization or debugging needs, the user can select subsets of the test to run — focusing on specific lanes, full or reduced data rate, or specific stress frequencies.

Not only does the automation software provide easy compliance, with printable test reports, but it also features powerful debugging tools such as views of the Sink Device registers, Configuration Data registers, and Enhanced Display Identification Data. The contents of registers defined to permit external writes can be edited from the keyboard.

BERTScope DP SINK CTS includes:

• BERTScope Stressed Pattern Generator with enhanced SSC
• Aux Channel Controller
• Automated Lane Switch
• DP Test Automation and Control Software

The BERTScope DP SINK CTS is also available without the Stressed Pattern Generator for users who prefer a full BERTScope for Sink and Source testing. The recommended model is the BSA7500B with option Opt-XSSC.

Also Required:
Host PC with Microsoft Windows XP or Vista operating system (any 32-bit version), Ethernet or GPIB, and two unused USB 2.0 ports.
