The Teledyne LeCroy quantumdata M42d Video Analyzer/Generator provides functional and will support compliance testing for video, audio and protocol of DisplayPort 2.0 and DisplayPort 1.4. The M42d supports legacy DisplayPort lane rates of 1.62, 2.7, 5.4, 8.1 Gb/s and the new DP 2.0 higher speed lane rates of 10.0, 13.5, & 20.0 Gb/s data rates with the new line coding—128b/132b. The protocol analyzer provides a snap shot status view and deep analysis using captures of incoming DisplayPort 2.0 streams from source devices including DSC/FEC compressed streams. The M42d’s video generator can be used for testing silicon as well as devices such as displays, USB-C adapters, extenders, etc. The video generator offers a large library of standard video timings and test patterns necessary for testing next generation high resolution displays.

The M42d supports legacy DisplayPort lane rates of 1.62, 2.7, 5.4, 8.1 Gb/s and the new DP 2.0 higher speed lane rates and new line coding—128b/132b—of 10.0, 13.5, & 20.0 Gb/s data rates on 1, 2 & 4 lanes. The protocol analyzer provides a snap shot status view and deep analysis using captures of incoming DisplayPort 2.0 streams from source devices including DSC/FEC compressed streams. The M42d’s video generator can be used for testing silicon as well as devices such as displays, USB-C adapters, extenders, etc. The video generator offers a large library of standard video timings and test patterns necessary for testing next generation high resolution displays.

A Passive Probe feature, based on Teledyne LeCroy's cutting-edge T.A.P.4™ technology, enables full monitoring of the DisplayPort Main Link and the Aux Channel between two DisplayPort devices up to 20 Gb/s lane rates. For developers of Embedded DisplayPort (eDP), the M42d offers fast link training, alternate scrambler seed, Advanced Link Power Management (ALPM) and Tx backlight control. A pin header is available to provide access to the backlight Tx control test feature.
