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.

3.1 Power Considerations
The 280 Test Set has a rocker style power switch on the back panel. Refer to the photo below.
The 280G and 280A are portable battery powered test instruments. They are equipped with rechargeable batteries.
Typically, you can use the 280 instruments on batteries for about 4-6 hours after a full charge. Teledyne LeCroy
recommends that you set the screen brightness to the minimum level required. Turn the unit off when not in use.
The 280G and 280A are Test Set is supplied with a 12V DC power supply and charger with an associated line cord.
Important Notes about power usage and status:
Monitor the battery meter on the lower right.
A green indication or partial green indication shows the battery is being charged.
A blue color with an electrical charge icon indicates that the device is being powered through the wall charger.
Fully charge the 280 units overnight.
Do not continue using the 280 units from battery power when the battery meter indicates that the batteries are
exhausted.
The following screen shows a charging battery condition.
The following example shows a nearly charged battery condition while the unit is running on batteries.

will activate an item on the screen or take you down to a lower level menu. A +indicates that you have to double touch to
navigate down to a lower level menu.
Note: Teledyne LeCroy recommends using a stylus or suitable plastic item with a blunt end to activate the buttons on the
280 screen. Selecting with your finger is sufficient however a stylus is preferable. You should not expect a similar touch
response that you have with a mobile phone.

4 Using the 280G to Run Video and Audio Tests on Displays and TVs
This Chapter provides procedures for using the 280G to run video and audio tests on high definition sink devices such as
HDTVs and projectors but you can also run tests downstream on entire distribution networks. The following signal types
are supported.
HDMI
HDBaseT
4.1 Making Physical Connections
The first step in testing a sink device is to make the physical connections between the 280G and the device(s) under test.
Connecting the 280G to the Display Device
Use the following procedures to make the physical connections from the 280G to the display device under test.
1. Make the cable connection between the 280G video output connector (e.g. HDMI OUT or HDBaseT OUT) and the
input connector of the sink device under test.
The following illustrations depict typical test configurations.
280G connected to an UHD TV via an HDMI cable
280G connected to a projector via HDBaseT

4.2 Selecting a Signal Type and Resolution
After making the physical connections between the 280G and the display device under test you will need to select the
Signal Type, Resolution and Frame Rate for the sink device under test.
Selecting Video Formats
The procedures below describe how to select the active signal type.
1. Power up the 280G using the rocker switch on the top edge. Review the guidelines for battery usage above.
2. From the Home page touch select the Signal Type activation button on the bottom status panel as indicated below.
3. Touch select the interface type (Connector), HDMI or HDBaseT.
Example shows HDMI being selected. You can also select DVI once HDMI is selected.

Revision 5
Example shows HDBaseT being selected.
HDBaseT has “Long Reach”mode which enables transmission of a 1080p60 signal to go 170 meters on Cat7 cabling.
4. Touch select the options for the Signal Type such as the Color Space, Sampling, Bit Depth and Format Type in
accordance with your requirements.
5. Touch select the options for the Signal Type such as the HDR in accordance with your requirements. Example below
shows HDR selected.
Selecting an HDMI Resolution and Frame Rate

280 Test Set –Quick Start Guide Page 18
May 11, 2018
Revision 5
The procedures below describe how to select the resolution.
When you make a physical connection to an HDMI HDTV (or an HDBaseT input port), a hot plug event will occur. There
are two modes the 280G can be set in when testing HDMI sink devices that determine how the 280G responds to this hot
plug event:
Hot plug formats On –This mode will cause the 280G to select a preferred timing in the EDID of the connected
sink device. Supported formats will be indicated in white text. You can select formats that are not supported but
the frame rates of unsupported frame rates will be shown with red text. You will be able to select other formats
that are not supported by the sink device.
Hot plug formats Off –This mode will show all supported formats on the 280G in white text.
For the HDMI and HDBaseT formats, there are color codes that are applied to the Resolution and Frame Rate selections.
The following is a summary of their meaning:
A Resolution or Frame Rate with white lettering but with no outline –a Resolution or Frame Rate that appears in the
EDID and has a short video descriptor associated with it.
A Frame Rate with green lettering and with white outline –The Frame Rate that is currently selected.
A Frame Rate with red lettering but with no outline –The Frame Rate is not supported by the EDID for that
Resolution.
A Frame Rate(s) with green lettering and with white outline –The Frame Rate along with the currently selected
Resolution that is the “preferred” timing.
A Frame Rate with black lettering but with no outline –The Frame Rate is not supported by the standard for the
selected resolution.
1. Select the Preferences from the 280G top level menu.
2. Select the Hot Plug Formats mode to On or Off as desired. Refer to the screen below.

3. Touch select the resolution and frame rate (middle button on the bottom panel). Refer to the figures below.
The following is an example with a 4K format selected.
The following is an example when Hot Plug formats is turned on for 720p formats.
The following screen shows red text where a format is not supported in the EDID received at the 280G. Note that you can
select these other formats.
