A new DisplayPort Type-C transmitter test solution is said to significantly reduce compliance test times compared to older schemes. According to real-world field evaluations, the highly optimized solution for use with Tektronix high-performance oscilloscopes allows engineers to complete the full suite of DisplayPort Type C compliance tests in less than six hours compared to competitive offerings that require up to 16 hours to complete.
In addition to full automation and shorter test times, the new release of the Tektronix DisplayPort test solution also integrates support for the Type-C specification including automated test setup and timer pop-ups to help users perform hands-free testing.
One of the key features of this release is the introduction of the DPOJET measurement library which helps in characterizing silicon and debug. If any of the tests fail during compliance testing, users can tap into the DPOJET DisplayPort measurement library for a deeper dive into the failures, such as eye diagram mask hit failures, and look at the relation between pre-emphasis level vs. voltage swing tests to perform root cause analysis. The solution also gives users the flexibility to configure measurements at different settings, make configuration changes in existing measurements on the fly, and run tests in single-shot or free-run repetitive modes.
The DisplayPort TX automated solution supports the compliance tests per DisplayPort 1.2 Type-C Spec and CTS using the TekExpress framework, a state-of-the-art tool designed for automation. The backend automation engine is based on Iron Python which uses socket-based programming and .Net remoting. Socket-based scripting interface is a de-facto standard that allows engineers to integrate an automated Tektronix solution into their automation environments.
TekExpress framework provides a simplified user experience with a single panel for device-under-test (DUT) configuration. It now includes DUT automation support using an Unigraf DPR-100 reference sink auxiliary controller. Enhanced reporting options let users generate reports in .html, .mht, .pdf and .csv formats. Data logging in .csv format helps users to collect results and analyze system behavior in depth, with both live and offline waveform analysis available.
The Tektronix Option DP12 application is compatible with Tektronix DPO/MSO70000 and DPO70000SX series oscilloscopes. The solution is available now worldwide and can be downloaded from the Tektronix website. Pricing is $11,800 US MSRP.
