    Overview You can operate and program the generator from an external computer or terminal using the optional IEEE-488 (GPIB) interface. The GPIB interface enables the generator to be used as a programmable video signal source for integration into automated test systems that use IEEE-488 or GPIB communications between instruments.

  • Page 171: 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 172: 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 173: Sending Commands And Queries

    Sending commands and queries The generator parses command lines one at a time. Command lines must be terminated with a carriage return (<cr>).The generator immediately echoes each character as it is received and places it in a command line buffer. This buffer currently has room for a total of 256 characters.

    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.

    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.

    Creating image catalogs An image catalog is an XML file that lists image names. When a catalog is enabled, the image names in the catalog appear in the Content list. You can create image catalogs and use them to control which image names appear when you press the Content key. If your test environment requires only a subset of the built-in images (for example, only images for testing TV CRTs), you can create an image catalog containing only those image names.

  • Page 291 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 292 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 293 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 294 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 295 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).
