Page 210: Creating Custom Formats Using The Command Line Interface
Creating custom formats using the command line interface There are two methods for creating formats through the command line interface. The first method is to use the FMTN command to set all format parameters in the format buffer to their default values, and then modify each value. The second method is to select an existing format to use as a template for the new format, and then modify only the values needed to create the new format.
Page 211: Format Catalogs
Format catalogs Scrolling through all of the available formats on the Source list can be time consuming. This is particularly true if you regularly use only a few formats that may be scattered throughout the list. You can set up the generator to show only the formats you want, in the order you want, when you browse through the Source list.
Page 212: Creating Format Catalogs
4. Press the soft key adjacent to a catalog to enable or disable it. A + sign next to the item indicates the item is enabled; a - sign indicates it is disabled. For example, to see only the VESA formats when you press the Source key, disable all catalogs except DMT and CVT.
Page 213: Deleting Format Catalogs
Note: If other catalogs are also selected, the Source list will include the formats in those catalogs as well. Note: If you power cycle the generator you will have to reinstate the format catalogs by loading with DIRL and using it with DIRU. To create a format catalog with both custom formats and default formats: 1.
Page 214 To delete a format catalog through the command line: 1. Establish a session with the generator using HyperTerminal over a serial connection or Telnet over an Ethernet LAN.

Page 221: Queries And Commands
Queries and commands The GPIB interface is an ASCII command line interface like the RS-232 command line interface. The communications protocol is per IEEE-488.2 specification. Queries and commands consist of four ASCII upper/lower case characters. Commands do not require a response from the generator, while queries cause the generator to respond with the required data.
Page 222: Queries
For example, the following number can be represented in three ways: • Integer (42) • Floating point (42.00) • Scaled floating point (4.200E+01) Queries Queries are comprised of a header followed immediately by a question mark (?). If there are any characters between the query header and the question mark character (including whitespace), a command error will result.

Page 277 • When testing for pixel anomalies, use the Flat, Raster, and Ramp images. Use the Raster and Flat images to look for pixels that may be stuck on or off, respectively. The luminance should increase uniformly for the Ramp image. Also look for sparkles indicating problems with sampling.
Page 278: Testing Hdmi 1.3 Displays
Testing HDMI 1.3 displays This section provides procedures for testing HDMI 1.3 deep color displays using the 882E. There are specific images that have been created to test HDMI 1.3 deep color displays and there is an Image Control Tool accessible from the 882E web page interface that enables you to control these images.
Page 279 The the Image Control Tool is accessible through the 882’s home web page. It enables you to change various format and 882 parameters, that applied to the test images, through a browser. The following is a view of the Image Control Tool: The following table describes the functions on the upper most tabs of the Image Control Tool.
Page 280 The following is a sample of the RampDif image is rendered on a display. Refer to the image and table below to better understand the configuration and use of this image. Chapter 9 Testing HDMI Sink Devices...
Page 281 The following table describes the parameters of the Ramp12 image through Image Control Tool. Function/Field Function Starting Level This slide bar sets the beginning (left most) grayscale level in the ramp. This is expressed as a percentage of the total range defined by the setting of Number of Bits per Component (NBPC) from 0% to 100%.
Page 282 the maximum range available is (3760 - 256 = 3504) grayscale levels. Since PELD is set to 32 (24 pixel depth in the 882) the maximum number or grayscale levels that can be rendered by the 882 on a display is 1024. So if you set the Starting Level at 25%, the Ramp12 image will begin at the left with a grayscale level of 1132 (3504 * 0.25 = 876 + 256) and end at the right with a grayscale level of 2156 (1132 + 1024 = 2156).
Page 283 Refer to the image and table below to better understand the configuration and use of this image. The following table describes the parameters of the Image Control Tool. Function/Field Function Color 1 These slide bars set the beginning color component and grayscale level (left most value) of the top and bottom ramps.
Page 284 Function/Field Function PELD This is the pixel depth within the 882. It defines the number of colors available to the 882 for rendering simultaneously on an image. The valid values for the PELD pulldown select box are 8 and 32. A setting of 8 means there is a maximum of 256 on-screen luminance levels per ramp.
Page 285 the maximum range available is (3760 - 256 = 3504) grayscale levels. Since PELD is set to 32 (24 bit depth) the maximum number or grayscale levels that can be rendered by the 882 on a display with the RampDif image is 1024 (512 per ramp). So if you set the Color1 slide bar at 25% and the Color2 slide bar at 75%, the level on the left of the top ramp would be 1132 ([3504 * 0.25] + 256 = 1132) and the level on the right end would be 2884 ([3504 * 0.75] + 256 = 2884).
Page 286 Refer to the image and table below to understand the configuration and use of this image. The following table describes the parameters of the Image Control Tool. Function/Field Function Color 1 These slide bars set the color component and grayscale level for one set of tiles.
Page 287 Function/Field Function Gamut (Range) Sets the number gamut of the output signal. This corresponds to the DVQM parameter. The values are Max (DVQM=0), MaxTV(DVQM=1) and NomTV (DVQM=2) this is the default for TV formats. Clr (Color) Space This pulldown select box specifies the color space. This field corresponds to the DVST and DVSM commands.
