1 Overview of the 280G & 280A Test Set
Important Note: Please check the quantumdata 280 webpage for updates to this Quick Start Guide.
The 280 Test Set is a battery-powered, portable Video Generator and Analyzer set that enables you to conduct quick, on-
site verification testing of your HDMI and HDBaseT devices, cables and entire distribution networks. The 280 Test Set is
comprised of:
280G Video Generator - Provides HDMI Tx port operating up to 18Gbps (600MHz) and an HDBaseT Tx port
operating up to 300MHz pixel rate.
280A Video Analyzer - Provides HDMI Rx port operating up to 18Gbps (600MHz) and an HDBaseT Rx port operating
up to 300MHz pixel rate.
Because the 280 instruments have both HDMI and HDBaseT outputs and HDMI and HDBaseT inputs, you can test your
HDMI and HDBaseT cables and systems with splitters, extenders and switches whether in your lab or installed on-site.
