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 “

Setting Source list

of formats” on page 43.

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 “Selecting image” on page 47 or Appendix B, “Image Reference.”

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:

XVSI 8 // Selects the SDI interface

ALLU // 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

HDMI-H

1 2 ... 82 83 84 85 86 87 88 89 90 91 92 ... 125 126
