1.2 Topics Covered in this Quick Start Guide

The following high level tasks are described in this Quick Start Guide:

Set up procedures

Provisioning the IP address of the M42de

Installing the M42de VPS GUI on a PC

Establishing an IP session between an M42de and the host PC

running the VPS GUI

Connecting the DisplayPort source or sink devices under test to

the M42de

This Quick Start Guide does not include descriptive or procedural

information for any of the video test functions of the M42de applications

themselves. Procedures for the functional applications are covered in the

M42de User Guide. The User Guide is available from the product page

on the Teledyne Lecroy website: Teledyne LeCroy - quantumdata

M42de Video Analyzer/Generator.

Note: Please be sure to check the Teledyne Lecroy website (Teledyne

LeCroy - quantumdata M42de Video Analyzer/Generator) for updates to

this Quick Start Guide & User Guides.

1.3 About the M42de

The M42de is a compact versatile test instrument offering entry level

functional testing that can be extended through software licenses to a full

compliance tester with sophisticated analysis and diagnostic capabilities.

M42de 80Gbps Video Analyzer/Generator

2About the VPS GUI Application

The M42de is operated through the embedded Video Protocol Suite

(VPS). The VPS is a GUI application that can run either on a Windows

host PC or on an external display connected to an HDMI port.

Note: The VPS GUI is activated by default for M42de systems.

Instructions for operating through the legacy ATP Manager is provided in

the User Guide. You can switch between the ATP Manager (legacy GUI)

and the VPS GUI using the procedure provided in Section 2.1.

When operating from a host PC, the VPS and/or ATP Manager

application has to be installed on the PC. When operating using an

external display, a mouse (provided) is required and a keyboard is

optional but recommended. These operational scenarios are shown in

the following images.
