Testing SDI and HD-SDI digital component video studio
displays
This section describes how to test SDI and HD-SDI digital component video for HDTV flat
panel displays.
To set up the generator to test a digital (SDI/HD-SDI) component video HDTV display:
1. Connect a coaxial cable between the SDI/HD-SDI BNC connector on the generator
and the SDI/HD-SDI BNC connector on the studio display under test.
2. Identify the component studio formats to test. These formats are listed after the
composite studio formats in the generator’s default Source list. See “
3. Determine additional formats to test based on the resolution of the studio display. The
studio monitor product specification sheet will provide information on what resolutions
to test. It is necessary to test only those resolutions with the supported scanning type.
4. Determine the images to test. For digital studio displays, you would typically want to
select images to test for pixel anomalies, persistence, photometry, and
resolution-related problems. For more details on which images test these specific
display attributes, see “
To activate the SDI/HD-SDI interface on the output port:
1. Press the
Interface key. A listing of signal interfaces appears on the generator’s display
as shown below.
2. Choose the
SDI item by pressing the adjacent soft key. The interface is activated and
the port outputs the currently selected image and format.
Alternatively, to activate the interface through the command line interface, enter the
following commands:
8
// Selects the SDI interface
// Applies the interface setting to the generator
To verify the test set-up:
1. Press the
Source key to access the list of formats.
2. Choose a component studio format (for example, 720p50) by pressing the adjacent soft
key.
Alternatively, you can load the format with the following command:
VGA
HDMI-D
CVBS
S-VIDEO
SDI
