Overview

The Teledyne LeCroy quantumdata M42de Video Analyzer/Generator provides an unprecedented combination of functional and compliance testing for video, audio and protocol layers for DisplayPort 2.1 source, sink and repeater devices. The M42de supports legacy DisplayPort HBR3 lane rates of 1.62, 2.7, 5.4, 8.1Gb/s and the new DP 2.1 UHBR lane rates of 10.0, 13.5 & 20.0Gb/s. Now enhanced to support DP80 connections over full size DisplayPort cables in addition to USB Type-C® cables, the M42de is your 'one-stop' solution for DP 2.1 testing and certification.

Highly Configurable

The quantumdata M42de is a highly configurable platform for testing DP 2.1 (and 1.4) source and sink devices with quick real-time views as well as full capture of main line video including meta data and AUX transactions. Invaluable for testing silicon development boards, displays, docking stations, hubs, USB-C adapters, retimers and extenders. The video generator offers a large library of standard video timings and test patterns necessary for easy verification of next generation displays. A complete API for automated testing is now available for compliance testing.

Flexible Hardware

The M42de supports generation and analysis of the DisplayPort data streams through the user-friendly Video Protocol Suite Manager. The M42de features an embedded CPU (linux-based) that operates as a stand-alone platform by connecting an HDMI monitor plus keyboard/mouse. Optionally an external laptop can be connected directly to the unit (via RJ45 LAN port) and control the analyzer as a remote PC. Both approaches provide fast access to captured video logs up to 8GB in size. The Passive Probe feature based on Teledyne LeCroy’s cutting-edge T.A.P.4™ technology, enables full monitoring of the DisplayPort Main Link and AUX Channel between two DisplayPort devices at the full 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.

Compliance

Source Link Layer Compliance

The DP source link layer compliance option is ideal for pre-testing HBR3 or UHBR-capable devices prior to submission to an Authorized Test Center.

Sink Link Layer & EDID Compliance

The DP sink EDID/DisplayID and Link Layer compliance option fully supports DP 1.4 certification and a growing list of DP 2.1 tests.

LTTPR Source, Sink & Retimer Compliance

The quantumdata M42de provides automated, one-button testing of Link Training Tunable Phy Repeater (LTTPR) compliance.
