Overview of 780780E Protocol Analyzer / Generator
This section provides an overview of the Teledyne LeCroy quantumdata™ 780E
Video Generator / Analyzer. The 780E provides HDMI, HDBaseT and DisplayPort
and Tx and Rx ports and digital audio output ports. The HDMI ports support
600MHz operation. The DisplayPort ports support 5.4 Gb/s lane rates and the
HDBaseT ports support 300MHz pixel rates.
Note: The DisplayPort interfaces are optional with the 780E P/N 00-00251;
they are standard with the 780E P/N 00-00243.
Scope of this Quick Start Guide
This Quick Start Guide provides instructions on the 780E connectors, power up
instructions and basic turn up procedures. This Quick Start Guide does not
provide instructions on the operational features and functions of the 780E.
Please refer to the 780E User Guide available on the Quantum Data website for
detailed instructions on the operation of the 780E to achieve the variety of
applications it supports.

780E Video Generator / Analyzer
The 780E Video Generator / Analyzer is a handheld multimedia pattern generator
and analyzer that enables you to conduct quick, verification testing of your
digital video devices, systems and installations. The 780E is equipped with
both reference source and a reference sink HDMI, DisplayPort and HDBaseT
interfaces allowing you to test audio, video and protocols—HDCP, EDID, CEC &
infoframes, DP Link Training—of any type of these digital video interface
devices: sources, repeaters, distribution gear and sinks. Its portability
makes it ideal for your bench and for use in the field. Because the 780E has
both output and input ports, you can test your digital video cables and
systems with splitters, extenders and switches as well with the pixel error
rate test feature.
A 7 inch color touch display makes the 780E easy and convenient to use. When
testing a digital video source device you can toggle between operating the
unit through the touch screen and viewing the incoming video from the source
.
