Interoperable Testing By Teledyne LeCroy’s Video Analyzer and Generator

  • Supports high data rate for high-resolution display
  • Best suited for AR/VR applications, as well as other test devices

Teledyne LeCroy has announced the availability of the quantumdata M42d Video Analyzer and Generator, the industry’s first DisplayPort 2.0 protocol test instrument. This allows designers and test engineers to conduct interoperable testing with other test devices.

The DisplayPort 2.0 provides data rates of up to 20Gb/s per lane for an overall aggregate bandwidth of 80Gb/s. This goes well beyond the DisplayPort 1.4 standard’s aggregate rate of 32.4Gb/s. These data rates support high screen resolutions of up to 16k with a 60 Hz refresh rate.

Enhanced functionalities

Quantumdata M42d system supports both Source and Sink testing at new data rates and line coding, as well as enhanced capabilities like LTTPR emulation and Panel Replay. The Capture Analyzer functionality provides deep visibility into the Main Link. And the Aux Channel Analyzer logs the Aux Channel transactions.


The M42d incorporates built-in passive probing based on Teledyne LeCroy’s state-of-art T.A.P.4™. “Adding the passive probing option allows for non-intrusive monitoring of the Aux Channel and Main Link between devices and is especially valuable at the higher data rates offered by DisplayPort 2.0,” said Neal Kendall, Product Manager for Teledyne LeCroy’s Video products.

“As consumer electronic products, ranging from desktop PCs and displays to mobile and wearable devices increasingly incorporate the DisplayPort digital interface to drive higher video resolutions and frame rates, it is essential for the ecosystem to have test tools for both specification and product development, as well as product compliance testing. We depend on efforts of VESA® member companies like Teledyne LeCroy to provide comprehensive test solutions for DisplayPort 2.0 silicon and devices,” said Bill Lempesis, executive director of the Video Electronics Standards Association (VESA), which develops and administers the DisplayPort standard and compliance logo program.

The device is perfect for applications like AR/VR and gaming.

All compliance test suites for DisplayPort 1.4 data rates are available now and DisplayPort 2.0 Link Layer compliance tests will be added as they are defined by the committee.
