Product overview

The generator enables you to test a broad range of video displays including composite or component television video signals as well as computer video display terminals. The generator enables you to quickly set the format appropriate for each display simply by twisting a knob. The generator’s functions can be customized to support video display testing in a variety of environments such as development, repair center, or production line.

Standard features

There are over 250 built-in video formats with the generator including VESA, ATSC, EIA-770, SMPTE, NTSC, and PAL. The generator contains a library of over 250 test images which enables comprehensive testing of color, size, linearity, convergence, focus, persistence, and more. You can create custom formats and images, and create test sequences to automatically progress through a list of formats and images for production line environments. You can also configure the generator to continuously loop through the test images.

The generator provides a hot sync feature through the VGA, DVI, or HDMI interface. This feature simplifies format selection by filtering formats in accordance with the Extended Display Identification Data (EDID) it receives and processes from the display.

A probe pulse feature is available on the Special Sync BNC connector. This enables you to trigger an oscilloscope or to synchronize an inspection camera. You can position the leading edge of the probe pulse anywhere within the video frame. This feature facilitates troubleshooting by enabling you to focus on very specific video signal problems occurring anywhere in the video signal. The probe BNC connector can also be configured to output frame sync, line sync, composite sync, or a special probe pulse.

You can control the generator using the front panel knobs and keys, a command line interface, or a Windows-based graphical application called Video Generator Manager (VGM).

The generator supports custom data backup, automatic or on-demand calibration, and downloadable firmware upgrades.

Optional features

Your generator may include one or more of the following options:

• Digital Visual Interface (Single Link and Dual Link). The generator can be equipped

with a single link or dual link Digital Visual Interface (DVI) transmitter. The DVI transmitter enables testing of DVI compliant video displays. The DVI option includes EDID parsing and a hot-plug, EDID-driven format list.

Operating the generator

This section describes basic operating procedures. There are four operational interfaces for controlling the generator.

• Physical control s. Most of the generator’s features and functions are supported using

the front panel using the knobs and keys. Functions which are not supported using the front panel include upgrading the firmware, creating and editing formats, creating and editing images and reconfiguring the format and image knob lists.

• Command line. An ASCII command line interface, available through the RS-232 port,

allows you to send commands either interactively or as command files. All functions are supported by the command line interface except upgrading firmware.

• Video Generator Manager (V GM). VGM is a Windows-based application that supports

most generator functions using a graphical user interface. When upgrading the generator firmware, VGM must be used.

• GPIB Programmatic interface (optional). An IEEE-488 GPIB interface supports the

use of the 802 as a programmable video signal source in an automated test evironment. All generator commands are supported through this interface.

Physical controls

The physical controls on the generator consists of the Format knob, Image knob, and eight keys, arranged into four function groups: Image, Video Gate, Sync Gate, and Outputs. All of the keys have built-in indicator lights. When illuminated, a key’s function is considered on, or enabled.

Power switch

This rocker switch turns the power on and off. The power supply is auto switching and can handle 110 or 220v.

Format knob

The Format knob is used to select a video signal format from a list of stored formats. A format is a set of parameters that specifies the video and sync signal requirements of a particular timing. Format parameters include timing, sync type, video type, display size, and others. By turning the knob, you can scroll through a list of formats stored in non-volatile memory. The list includes the factory default formats. The knob list can be edited to add custom formats. If a format containing erroneous information is selected, the generator turns off the outputs, and displays an error message.

4 Chapter 1 Getting Started

Image knob

The Image knob is used to select a test image from a list of stored images. The exact behavior of the knob depends upon the status of the Image key. Turning the knob when the light on the Image key is extinguished scrolls through the main list of test images.

Not all images are supported by all signal formats. Some images in the main image list may be skipped while certain formats are selected. For example, the ColorBar image will be skipped whenever a monochrome format is selected.If the currently selected image cannot be drawn given a newly selected format, the Outline image is automatically drawn after the new format has finished loading.

Some of the image names in the main list may refer to a sub-set of two or more different images. The images in the sub-sets are selected by first selecting the name of the desired sub-set from the main image list. If the sub-set consists of just two images, pressing the Image key will toggle between the two images. The key is illuminated when the second image is showing.

Image Step key

The Image Step key determines the behavior of the Image knob in normal operating mode where it is used to select alternate versions of a given test image. The Step key will illuminate only when you have selected an image with multiple versions. The following procedure describes how to select image versions.

To select image versions:

1. Using the Image knob, select an image that has multiple versions.

2. Press the Step key. The key illuminates.

3. Turn the Image knob to step through the image versions. As you turn the knob, the

image name on the LCD will not change.

4. Press the Step key again. The light on the key extinguishes, and the Image knob

returns to normal operation.

The following procedures describe how to setup a terminal session with the generator using the RS-232 interface.

To setup a terminal connection with the generator:

Whenever the generator is powered on, the baud rate returns to 2400 bps, no parity, 8 data bits, 1 stop bit, and no handshake.

1. Connect the RS-232 cable between your computer or terminal and the serial connector on the generator.

2. Using a terminal emulator, such as HyperTerminal, establish a terminal connection with the generator. Configure the terminal emulator to use the following parameters:

• 2400 baud rate

• 8 data bits

• 1 stop bit

• no parity

• no handshaking

• full duplex

3. Press the Enter key until the R:> prompt appears.

14 Chapter 1 Getting Started

Changing the baud rate

The RS-232 interface can be configured from the physical controls to support faster baud rates and to supprort a remote keypad (optional accessory). The default configuration is 2400 baud. When the generator is powered on, the baud rate returns to the default configuration.

To support file transfers, you can change the baud rate of the port to 38400 bps using the command line interface or 9600 bps using the physical controls.

To increase the baud rate using the command line interface:

1. At the R:> prompt, enter the following command:

MODE 38400 n, 8, 1, h, n

After you press Enter, the terminal emulator will lose its connection with the generator, which is now set at a different baud rate.

2. Close the terminal emulator session, change the baud rate to 38400, and then re-open the session, specifying the baud rate as 38400.

To change the baud rate to 9600 using the front panel:

1. Turn off the generator.

2. Hold down the R and DCS keys while starting the generator. The serial port is now set to 9600 bps. Restarting the generator again, without pressing any keys, will

Sending commands interactively

This procedure describes how to send commands through an interactive user session. 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. When sending multiple commands at once, separate each command with a semi-colon. Commands are not case sensitive.

To send single commands to the generator:

1. Establish a terminal session with the generator (see page 14).

2. At the R:> prompt, enter commands or queries and terminate with a carriage return.

Command examples

• To display the name of the format currently in the format buffer, enter:

FMTL?

• To load a format, enter:

FMTL format_name

802BT/802R Video Test Generator User Guide 15

• To apply the format to the generator hardware, enter:

FMTU

• To load an image, enter:

IMGL image_name

• To apply the image to the generator hardware, enter:

IMGU

To send multiple queries and commands to the generator:

1. Establish a terminal session with the generator (see page 14).

2. At the R:> prompt, enter the queries or commands, separating each with a semi-colon and terminating the command line with a carriage return.

Command examples:

• To query the current format and then load a new format enter the following:

FMTL?; FMTL new_format; FMTL? FMTU

The generator will return the following in response to this command and query string:

current_format; new_format

• To change the format and image active in the generator enter:

FMTL 480p59; IMGL SMPTEbar; ALLU

This tells the generator to load the 480p59 format named “” into the format data buffer, the image named “SMPTEbar” into the image data buffer, and then to “use” the contents of both (“all”) buffers to drive the generator's output.

Sending commands from text files

When developing more complex, custom test sequences or formats, it is easiest to enter commands in a text file, and then send the file to the generator. This approach allows you to modify the file without entering the entire command script.

To send a text file to the generator:

1. Using a text editor, enter the commands that define a test sequence or format into a text file, and save the text file using a *.txt extension.

2. Establish a terminal session with the generator (see page 14).

16 Chapter 1 Getting Started

3. At the R:> prompt, transfer the text file to the generator. For example, to transfer a file using HyperTerminal, do the following:

a. On the Transfer menu, click Send Text File. The Send Text File dialog box

appears.

b. Select the text file you want to send, and then click Open. HyperTerminal displays

the commands as they are sent.

c. Press Enter once to ensure that the last command is sent.

This section explains how to configure the generator to output video formats that are supported by the device being tested.

DVST

Note: You can create your own formats. See “Creating custom formats” on page 63 for details. Additionally, you can create your own Format knob lists. See “Editing Format knob

lists” on page 67 for details.

Selecting formats automatically

When testing EDID-compatible displays, the generator can automatically update the Format knob list (list of format names shown on the LCD) to include only formats supported by the display under test. Depending on the output used, the generator can do this on demand, or automatically when a display is connected.

To update the Format knob list on demand:

1. Connect the display you want to test with the generator.

2. Hold down the R key, and then press and release the ACS key. This puts the generator into either Analog Friendly or Digital Friendly mode based on the EDID that the generator receives.

3. Turn the Format knob to choose a format. Only formats supported by the display are listed.

802BT/802R Video Test Generator User Guide 25

To update the Format knob list automatically when a dis play is connected:

1. Connect the display you want to test with the DVI or HDMI connector on the generator. (Analog outputs do not support this feature.)

2. Turn the generator off.

3. Hold down the R and ACS keys while starting the generator, until hot plug formats displays on the LCD.

Note: The generator is now in Digital Friendly mode.

4. Turn the Format knob to choose a format. Only formats supported by the display are listed.

5. Connect a different device to automatically update the Format knob list again.

Selecting formats manually

When testing a display that is not EDID-compliant, you must manually choose formats from the generator that are supported by the display.

To do this:

• Identifing the type of display (composite television, component standard definition television, component high definition television, computer equipment, or other specialty display).

• Check the specifications of your display for supported formats.

• Learn how the format library is organized, and how formats are named (see below).

• Turn the Format knob to try formats from the appropriate format category. Try the DMT0660 (VGA) format if you are not sure of which formats to use.

Understanding the format library

After connecting the generator with the display under test, turn generator on, and select a video format.

This section describes how to choose a video format, from the list of formats built into the generator, for the display you are testing. A format defines a set of video, timing and sync parameters for a specific device or standard.

A summary of the format naming convention is provided. For a detailed description of the naming conventions, see to “Format naming conventions” on page 56.

Organization of format library

The generator has several built-in formats to test a broad range of display types. These formats are grouped in the following categories:

26 Chapter 2 Testing Video Displays

• Composite television formats

• Component standard definition television formats

• Component high definition television

• Computer display formats

• Military and medical display formats

• Miscellaneous formats

When you turn the Format knob, the formats are listed in the order shown above.

Composite television f ormats

Composite television formats are named by the standards defining them. The first three to five characters of the format name indicate the color coding scheme. The first set of characters refers to the standard. The next characters are optional and indicate adjustments to the format. Examples of these formats are:

• NTSC (North American TV)

• PAL (European TV)

• NTSC-J - (where J refers to a Japan standard per NTSC without 7.5 IRE setup)

• PAL-N (where N indicates 3.58205625 MHz color sub-carrier)

• PAL# (where # indicates that the sampling rate is reduced to achieve square pixels)

Component standard definition television formats

Component SDTV formats are applicable in the case of RGB, YPbPr. These formats are named by their vertical resolution, scanning method, and frame rate. The initial characters indicating the resolution are followed by the scanning method. The two characters following the scanning method indicate the frame rate. A typical example of component standard or definition TV video format is:

• 480i2x30 (for a vertical resolution of 480 pixels with interlaced scanning and a 30 Hz frame refresh rate; 2x indicates that the pixels are double-clocked for DVI compatibility).

Component high definition television formats

Component high definition television formats, like the standard definition television formats, are named by their vertical resolution, scanning method, and frame rate. These formats are applicable in the case of RGB, YPbPr, and YCbCr. These initial characters indicating the resolution are followed by the scanning method. The two characters following the scanning method indicate the frame rate. A typical example of component high definition TV video format is:

• 1080i30 (for a vertical resolution of 1080 active vertical lines with interlaced scanning and a 30 Hz frame refresh rate).

802BT/802R Video Test Generator User Guide 27

Computer display formats

Computer display formats are assumed to use progressive scanning. Computer format names consist of four blocks. The initial three characters indicate the vendor ID using the EISA ID (for example, IBM, SUN, and VSC) or the standard body or acronym (for example, SMT, DMT, GTF, CEA, and EIA). The next two characters provide the first two digits of the horizontal resolution in pixels. Following the horizontal resolution are two characters which indicate the frame rate. The final character indicates the aperture, which is used only if the aperture is not 1.33 (A). The following are examples of computer display formats:

• VSC1275 for Viewsonic 1280 by 1024 at 75 Hz

• DMT0685 for Discrete Monitor Timing with 680 by 480 at 85 Hz

Viewing format parameters

You can use the Format image or VGM to view detailed information about formats in the generator.

To view formats parameters using VGM:

• Open each format in the Font Editor.

• Generate a detailed format listing.

Selecting images

Once you have determined the format or formats appropriate for testing the display you will apply a series of images suitable for evaluating the display. Of primary importance is determining what type of display you are testing (for example, CRT or digital flat panel display). You must also determine if you are testing composite TV and use images appropriate for these formats and video types.

Each image in the generator’s library is intended to test one or more attributes of a particular display type and video type.

Note: You can create your own images. See “Creating custom images” on page 75 for details. Additionally, you can create your own custom Image knob lists. See “ Editing Image

knob list” on page 81 for details.

Refer to the VGM online help for instructions.

30 Chapter 2 Testing Video Displays

Testing analog computer (IT) CRTs

This section describes how to test analog computer (IT) displays.

To test an analog computer CRT:

1. Use a standard VGA cable to connect the VGA connector on the generator with the VGA connector on the display under test.

2. Calibrate the generator by holding down the R, G and B keys while starting the generator. See “Calibrating the generator” on page 47.

You can also calibrate the generator by entering the following command:

SCAL

When calibrating the generator, if you load the analog outputs (as they will be loaded when conducting testing) then the calibrations will be slightly more accurate. This is not required however. Also, loading the unused outputs with 75 ohms will optimize signal damping.

3. (Optional) Enable the Status Display mode and Analog Friendly mode (see “Special

operating modes” on page 18). The Analog Friendly mode ensures that the generator

will output an analog signal. The Status Display mode enables you to view the current output characteristics on the LCD.

4. Determine the formats to test (see “Selecting formats automatically” on page 25).

5. (Optional) To view the EDID on the display, use the Image knob to select the EdidData image and follow the directions on the display. You may wish to view the EDID data to verify that the formats required for testing are specified in the EDID.

Alternatively, you can load the image with the following command:

IMGL EdidData; IMGU

6. Determine additional formats to test based on the resolution of the display. The VESA formats are shown below:

Standard Quantum Data format name

VGA DMT06xx

SVGA DMT08xx

XGA DMT10xx

SXGA DMT12xx

UXGA DMT16xx

QXGA DMT20xx

QSXBA DMT25xx

802BT/802R Video Test Generator User Guide 31

Determine the images to test:

For analog CRTs you typically want to select images to test for geometry, focusing, photometry, resolution, cross talk, EMI, and regulation characteristics. For more details on what images test these specific display attributes, see “Selecting images” on page 28 or Appendix B, “Image Reference.”

Verify the test set-up:

1. Using the Format knob, select one of the formats you have identified.

Alternatively, you can load the format with the following command:

FMTL format_name; FMTU

2. Using the Image knob, select a suitable image such as ColorBar. Verify that the display is presenting the image to ensure that the generator is sending a valid signal to the display.

Alternatively, you can load the image with the following command:

IMGL ColorBar; IMGU

Test the display:

1. Using the Format knob, select the first test format identified.

Alternatively, use these commands to load the format:

FMTL format_name; FMTU

2. Using the Image knob, select the first test image.

Alternatively, you can also load an image with the following command:

IMGL image_name; IMGU

3. Repeat steps 1 and 2 for all formats and test images. Use the following guidelines to verify proper operation:

• When testing geometry with the Hatch images (for example, Hatch20) look for

distortion with concave or convex lines near the periphery of the display. Look for irregular spacing on the cross hatch patterns.

• When testing photometry such as chrominance, use the ColorBar, SMPTE133, or

SMPTEbar images. Look for missing bars which may indicate a dead or

unconnected channel. Also, look at the transition between the bars; they should be sharp and distinct. Each bar also should be uniform in color and intensity across its entire width.

• To test luminance, you can use the SMPTE133 (grayscale portion) image. To test

gamma correction, you can use the SMPTE133 (checkerbox portion) image. The detailed methods for verifying these parameters on the SMPTE133 image are provided in Appendix B, “Image Reference.”

• When testing focus with the Focus or Text images, the characters in all areas of the

display should be well-formed and in focus.

32 Chapter 2 Testing Video Displays

• When testing resolution with the Grill images, you should be able to see individual

and distinct stripes in all areas of the display at all four resolutions.

• When testing for centering use the Outline images. For detailed methods for

verifying centering with the Outline images, see Appendix B, “Image Reference.”

• When testing for high voltage regulation with the Regulate image, observe the

outline at the edges of the image. They should stay in place and not pull away from the area of the large white blinking patch (when it appears).

Note: You can customize your generator to run through a specified set of formats and images automatically or manually b y creating test sequences. See to “Creating a test

sequence” on page 87 for details.

802BT/802R Video Test Generator User Guide 33

Testing digital computer (IT) FPDs

This section describes how to test digital computer (IT) displays.

To test a digital FPD:

1. Use a DVI-I cable to connect the DVI output on the generator with the DVI connector on the display under test.

2. Place the generator in Digital Friendly mode by holding down the G and B keys while starting the generator.

Alternatively, you can set the Digital Friendly mode by entering the following command:

SROP 2 4; ALLU

The Digital Friendly mode ensures that the generator will output a digital signal on the DVI connector, when selecting analog formats from the format library.

3. Determine the formats to test. Auto-select the formats to test by enabling the generator’s DDC-based auto configuration. See “Selecting formats automatically” on page 25 for instructions.

4. (Optional) To view the EDID on the display, use the Image knob to select the EdidData image and follow the directions on the display. Verify that the EDID specifies the formats required for testing.

Alternatively, you can load the image with the following command:

IMGL EdidData; IMGU

5. Determine which images to test. For digital flat panel displays, you typically want to select images to test for pixel anomalies, persistence, photometry and resolution related problems. For more information, see “Selecting images” on page 28 or Appendix B, “Image Reference.”

Verify the test set-up:

1. Using the Format knob, select one of the formats you have identified.

Alternatively, you can load the format with the following command:

FMTL format_name; FMTU

2. Using the Image knob, select a suitable image such as SMPTE133. Verify that the display is presenting the image to ensure that the generator is sending a valid signal to the display.

Alternatively, you can load the image with the following command:

IMGL SMPTE133; IMGU

Test the display:

1. Using the Format knob, select the first test format identified.

34 Chapter 2 Testing Video Displays

2. Using the Image knob, select the first test image.

3. Repeat steps 1 and 2 for all formats and test images. Use the following guidelines to verify proper operation:

• When testing photometry such as chrominance, use the ColorBar, SMPTE133, or

SMPTEbar images. Look for missing bars which may indicate a dead or

unconnected channel. Also, look at the transition between the bars; they should be sharp and distinct. Each bar also should be uniform in color and intensity across its entire width.

• To test luminance, you can use the SMPTE133 (grayscale portion) image. To test

gamma correction, you can use the SMPTE133 (checkerbox portion) image. The detailed methods for verifying these parameters on the SMPTE133 image are provided in Appendix B, “Image Reference.”

• When testing for centering use the Outline images. The detailed methods for

verifying centering with the Outline images (Outline0, Outline1, Outline2, Outline3) are provided in Appendix B, “Image Reference.”

• When testing resolution with the Grill images, you should be able to see individual

and distinct stripes in all areas of the display at all four resolutions.

• 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.

• When testing for persistence with the animated images (for example, Cubes and

Persist), look for bleeding or trails in the wake of the moving object.

Note: You can customize your generator to run through a specified set of formats and images automatically or manually b y creating test sequences. See “Creating a test

sequence” on page 87 for details.

802BT/802R Video Test Generator User Guide 35

Testing analog composite video SDTV (CE) CRTs

This section describes how to test CRT composite televisions with analog composite video inputs.

To test analog composite video SDTV:

1. Use a standard coax cable to connect the TV BNC connector on the generator with the display under test.

Or, use an S-video cable to connect the SVIDEO connector on the generator with the S-Video input on the display under test.

2. (Optional) Place the generator in Analog Friendly mode by holding down the R and B keys while starting the generator (see “Special operating modes” on page 18).

The Analog Friendly mode ensures that the generator will output an analog signal.

3. Determine which composite television standard you need, such as NTSC or PAL, and then select the formats compatible with the standard. Typically, you would test all the formats in the family of formats for a standard.

4. Determine the images to test. For analog CRTs you typically want to select images to test for geometry, focusing, photometry, resolution, cross talk, EMI, and regulation characteristics. For more details on what images test these specific display attributes, see “Selecting images” on page 28 or Appendix B, “Image Reference.”

Verify the test set-up:

1. Using the Format knob, select the first NTSC or PAL format.

Alternatively, you can load the format with the following command:

FMTL format_name; FMTU

2. Using the Image knob, select a suitable image such as SMPTEBar. Verify that the generator is sending a valid signal to the display and that the display is presenting it.

Alternatively, you can load the image with the following command:

IMGL SMPTEBar; IMGU

2. Using the Image knob, select the first test image.

Note: You can customize your generator to run through a specified set of formats and images automatically or manually b y creating test sequences. See “Creating a test

sequence” on page 87 for details.

3. Repeat steps 1 and 2 for all formats and test images. Use the following guidelines to verify proper operation:

36 Chapter 2 Testing Video Displays

• When testing geometry with the Hatch images (for example, TVHatch and

Hatch20) look for distortion with concave or convex lines near the periphery of the display. Look for irregular spacing on the cross hatch patterns.

• When testing photometry such as chrominance, use the TVBar100 & TVBar_75

(TV formats only), TVSplBar, SMPTE133 or SMPTEbar images. Look for missing

bars which may indicate a dead or unconnected channel. Also, look at the transition between the bars; they should be sharp and distinct. Each bar also should be uniform in color and intensity across its entire width.

• When testing focus with the Focus images, the characters in all areas of the display

should be well-formed and in focus.

• When testing resolution with the Grill images, you should be able to see individual

and distinct stripes in all areas of the display at all four resolutions. When testing for resolution with the Burst image, the peak intensities of the all of the bursts should match the white reference level. The darkest portions between the peaks should match the black reference level.

• When testing for centering, use the Outline and TVoutLin images. The detailed

methods for verifying centering with the Outline images (Outline0, Outline1,

Outline2, Outline3) are provided in Appendix B, “Image Reference.”

• When testing for high voltage regulation with the Regulate image, observe the

outline at the edges of the image. They should stay in place and not pull away from the area of the large, white blinking patch (when it appears).

Testing analog component video SDTV (CE) CRTs

This section describes how to test CRT televisions with standard definition component video inputs.

To test an analog component video SDTV display:

1. Use a VGA-to-RCA cable to connect the VGA connector on the generator with the YPbPr inputs on the display under test.

Or, if your generator has optional component BNC connectors, use a BNC to RCA cable to connect the BNCs on the generator with the RCA connectors on the display under test.

2. Identify the component television formats to test. These formats are listed after the composite television formats in the generator’s default Format knob list. Begin with the first format in the range of standard definition component television formats (480i).

3. Determine additional formats to test based on the resolution of the television display. The television specification sheet will provide information on what resolutions to test. It is necessary to test only those resolutions with the supported scanning type (typically, interlaced for a standard definition television).

Verify the test set-up:

1. Using the Format knob, select the first component video format (480i).

Alternatively, you can load the format with the following command:

FMTL 480i; FMTU

2. Using the Image knob, select a suitable image such as SMPTE133. Verify that the generator is sending a valid signal to the display and that the display is presenting it.

Alternatively, you can load the image with the following command:

IMGL SMPTE133; IMGU

Test the display:

1. Using the Format knob, select the first test format.

2. Using the Image knob, select the first test image.

Note: You can customize your generator to run through a specified set of formats and images automatically or manually b y creating test sequences. See “Creating a test

sequence” on page 87 for details.

Testing digital component video HDTV (CE) flat panel displays

This section describes how to test digital component video for HDTV flat panel displays.

To test a digital (DVI) component video HDTV display:

1. Use a standard DVI cable to the DVI connector on the generator and then to the DVI connector on the television display under test.

Note: If the display under test has a DVI-D connector you will need a DVI-I to DVI-D adaptor.

2. Place the generator in Digital Friendly mode by holding down the G and B keys while starting the generator (see “Special operating modes” on page 18).

This mode ensures that the generator outputs a digital signal on the DVI connector, even when selecting analog formats from the format library.

3. Identify the high definition component television formats to test. These formats are listed after the composite television formats in the generator’s default Format knob list. Begin with the first format (720p) in the range of high definition component television formats. See “Selecting formats automatically” on page 25.

4. Determine additional formats to test based on the resolution of the television display. The television product specification sheet will provide information on what resolutions to test. It is necessary to test only those resolutions with the supported scanning type (typically interlaced for a high definition television).

5. Determing which images to test. For digital television flat panel 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 images” on page 28 or Appendix B, “Image

Reference.”

Verify the test set up:

1. Using the Format knob, select the first HDTV video format (720p50).

Alternatively, you can load the format with the following command:

FMTL 720p50; FMTU

2. Using the Image knob, select a suitable image such as the SMPTE133 image. Verify that the generator is sending a valid signal to the display and that the display is presenting it.

Alternatively, you can load the image with the following command:

IMGL SMPTE133; IMGU

40 Chapter 2 Testing Video Displays

sequence” on page 87 for details.

3. Repeat steps 1 and 2 for all formats and test images. Use the following guidelines to verify proper operation:

• When testing photometry such as chrominence, use the ColorBar, SMPTE133, or

SMPTEbar images. Look for missing bars which may indicate a dead or

unconnected channel. Also, look at the transition between the bars; they should be sharp and distinct. Each bar also should be uniform in color and intensity across its entire width.

• To test luminance, you can use the SMPTE133 (grayscale) images. To test gamma

correction, you can use the SMPTE133 (checkerbox) image. The detailed methods for verifying these parameters on the SMPTE133 Image are provided in Appendix B, “Image Reference.”

• When testing for centering, use the Outline images. The detailed methods for

verifying centering with the Outline images (Outline0, Outline1, Outline2, Outline3) are provided in Appendix B, “Image Reference.”

• When testing resolution with the Grill images, you should be able to see individual

and distinct stripes in all areas of the display at all four resolutions.

• 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.

• When testing for persistence with the animated images (Cubes and Persist), look

for bleeding or trails in the wake of the moving object.

3 Administrative Tasks

The chapter describes how to accomplish common administrative tasks. Most administrative functions are supported through the front panel or command line interface. However, upgrading firmware can only be achieved through VGM; it is not supported through the front panel. Most administrative functions are supported through the VGM application. See the VGM online help for information on performing these administrative tasks through VGM.

Topics in this chapter:

• Displaying system information

• Restoring factory settings

• Calibrating the generator

Displaying system information

Use the GenStats image to display information about the generator, including revision levels of FPGA software installed. This image also list installed options.

To display information about generator:

1. Connect the generator with a display.

2. Choose a format supported by the display.

3. Turn the Image knob to select the GenStats image.

44 Chapter 3 Administrative Tasks

Restoring factory settings

This section describes how to set and restore the generator system parameters.

System Parameters

The following system parameters are stored in the 802’s non-volatile system memory:

• The reference rate calibration factor. The 802 uses a crystal controlled oscillator as the reference for all timing signals. The crystal frequency has a maximum error of ±50 ppm. The 802 hardware and firmware is capable of compensating for this small amount of error by applying a user set calibration factor. The factory default setting is 1.000 for the calibration factor. Use the

• The maximum pixel clock rate used for error checking formats. All 802 generators will operate, to some extent, at pixel rates beyond their spec sheet limits. The maximum rate can be set to a higher limit if it is known that a particular unit will work reliably at the higher limit. Use the checking of analog formats.

RATC

command to set the pixel calibration factors.

JRAT

command to set the maximum pixel rate used for error

• The gamma correction flag. This flag determines whether individual formats can control the application of gamma correction or if gamma correction is disabled regardless of a format’s setting. The factory default setting is to allow gamma correction to be controlled by individual formats. Use the gamma correction flag.

GAMC

command to enable or disable the

Setting and restoring system parameters

There are two ways of changing the settings of these parameters:

• They can be restored to their default factory settings as part of a user initiated system reset. This will also restore the entire format storage memory to its factory default contents.

• A suitably equipped computer or terminal connected to one of the communications ports can be used to set the parameters to user defined settings.

When the generator is reinitialized, each format in the standard library is tested (one-at-a-time), to determine if the format parameters are fully supported by the generator. This algorithm is necessary because the standard format library is used across all generators. If there are some limitation the generator applies a format justification algorithm. In these cases the generator stores a modified version of the format under a similar name. If the format is beyond what can be corrected the format is left out of the generator’s list of formats.

WARNING: The initializing the generator permanently and irreversibly removes all user-created formats, custom images, test sequences and directories from memory.

802BT/802R Video Test Generator User Guide 45

To re-initialize generator through system reset:

1. Hold down ACS and DSS while powering up the generator.

A confirmation message is displayed.

2. Press the Outputs key to continue, or press the Step key to cancel the operation.

To re-initialize and calibrate the generator using command interface:

1. Establish a terminal session with the generator (see page 14).

2. Enter the following command:

INIT

The generator then goes through a complete self-test and self-calibration procedure.

To re-initialize without calibrating the generator using the command line:

1. Establish a terminal session with the generator (see page 14).

2. Enter the following command:

BOIT

The generator is re-intialized.

46 Chapter 3 Administrative Tasks

Calibrating the generator

The 802BT/R generator can calibrate itself. Once calibrated, the generator does not require periodic calibration. There are no physical controls to adjust. All calibration is electronic. Calibration factors are saved in non-volatile memory.

The calibration accuracy of the generator for analog video voltage swing is specified to be ±14mV (or ±2% for a nominal 700mV signal). Using a typical oscilloscope such as a Tektronix VM700T, which might have a swing measurement accuracy of ±14mV, we should expect readings between 674mV to 726mV.

You can also set the analog output calibration factors to values other than those set by the generator's own self-calibration function. Each channel is calibrated using two independent zero calibration points, and two independent slope calibration points. Interpolation equations for the different video types are used to set the caldac values that controls the output sync and voltage levels to the correct values.

Follow the procedures below to calibrate the generator.

To self-calibrate the generator using the front panel:

1. It is not necessary to load the outputs of a generator during self-calibration. However, attaching a nominal load may yield a slight increase in accuracy.

2. Simultaneously depress all three R, G and B video gate keys and power cycle the generator.

The LCD will display a special message indicating that it is about to do a self-calibration.

3. Release the R, G and B video gate keys and the generator will begin its self-calibration routine.

You will see calibration factors flash on the display. Observe the display for any error messages that might occur. If an error message appears, make a note of it and call your technical support representative for further assistance.

To self-calibrate the generator using the command interface:

1. Establish a terminal session with the generator. See “Setting up a terminal connection

with the generator” on page 14.

2. Enter the following command:

SCAL

The generator then goes through a complete calibration procedure.

To view analog calibration factors:

1. Enter the following commands to view the analog video Red, Green, Blue calibration factors:

802BT/802R Video Test Generator User Guide 47

CALF?

The generator presents the following in response:

1089, 2589, 1993, 3223, 1148, 2633, 2059, 3279, 1000, 2505, 1990, 3219, 793, 787, 3382, 3509

Calibrating frequency

All frequencies associated with the generator are derived from a common frequency reference, which can be calibrated using the rate calibration command RATC.

To reduce all frequency errors to zero:

1. Measure any convenient frequency from the generator using a very accurate frequency counter.

For example, measure the horizontal TTL separate sync frequency with the DMT0660 format loaded and the horizontal rate temporarily set to 100KHz. Enter the following:

FMTL DMT0660; HRAT 100E3; ALLU

2. Measure the TTL horizontal sync frequency with the frequency counter.

3. Divide the frequency that you expect by the frequency that you measure on the frequency counter and enter that ratio using the

RATC

command.

For example, if you measure 99.9955782499875 kHz, when you expect

100.000000000KHz, then divide 100.000000000KHz by 99.9950002499875kHz and enter the following on the command line:

RATC 1.0000442194553987

This will raise all frequencies output by the generator and make them exact.

48 Chapter 3 Administrative Tasks

Cloning generators

This section describes how to copy configuration settings from one generator to other generators using a PCMCIA card. The entire block of battery backed user memory (including video formats, custom test images and test sequences) is copied from one generator to another using a suitable PCMCIA memory card.

The card you need is a Type 1, Battery Backed RAM PCMCIA card with at least 2 MB of storage. These cards are available from synchrotech P/N PCM-SRW-AM002 2MB. Flash or compact type memory cards will not work.

Note: See VGM online help for procedures for cloning generators using VGM.

To clone a generator using PCMCIA card:

1. Install the same firmware version on the source and target generators.

Note: This procedure can only be used when the firmware of the source and target generators are the same. To verify the firmware version, load the GenStats image.

2. Insert PCMCIA card into the source generator.

3. Hold down the Step and Outputs keys while starting generator.

4. Choose WR (press Outputs key) to copy the generator configuration to the card. The generator displays a Done message when it is done writing to the card.

5. Transfer the PCMCIA card to the second generator.

6. Hold down the Step and Output keys while starting generator.

7. Choose RD (press Step key) to copy the configuration data from the card to the generator.

All user-created objects on the target generator will be deleted. To cancel the operation, press the ACS key.

8. Hold down the ASC, DCS, and DSS keys while starting the generator to return the generator to normal operating mode.

802BT/802R Video Test Generator User Guide 49

Installing firmware

Firmware upgrades are available at http://www.quantumdata.com/support/downloads/.

Important: Always backup any custom ob jects (formats, images) stored on the gener ator before installing an upgrade. The firmware installation re-initializes the generator, which deletes any custom objects. After installing the firmware, you can restore custom objects.

Firmware upgrades require the use of VGM. Please refer to the VGM online help for procedures on upgrading the generator.

50 Chapter 3 Administrative Tasks

Memory management

The generator includes commands to manage its internal memory resources. These commands or useful if the generator exhibits degraded performance or other anomolies.

To verify and correct memory related anomolies:

1. Check the generator’s memory for corruption by running a memory self test:

MEMT // runs the memory self test MEMT? // returns the results of the memory self test

1 // returned value from the memory self test

A value of “0” indicates no memory corruption or inconsistency was found. A value of “1” indicates that there is a memory anomoly.

2. If the memory self test reveals a memory corruption, re-initialize the generator:

BOIT // re-initializes the generator

3. If the memory self test does not reveal a memory corruption, check to see if there is enough free memory and contiguous memory:

MEMF? // queries for the free memory

808320 // returns the amount of free memory

MEML? // queries for the largest contiguous block of free memory

816568 // returns the largest contiguous block of free memory

If the amount of memory is low or the amount of contiguous memory is low the memory should be compacted.

4. Compact the generators memory:

MEMC // compacts the memory MEML? // queries for the largest contiguous block of free memory

818280 // should show larger block of contiguous free memory

4 Working with Formats

Topics in this chapter:

• Overview

• Format library

• Format naming conventions

• Creating custom formats

• Editing Format knob lists

• Configuring DCS priority scheme

• Creating format aliases

802BT/802R Video Test Generator User Guide 53

Overview

The generators enable you to create your own formats and edit the Format knob list through the Video Generator Manager (VGM) application and the command line interface. Please refer to the VGM online help for details on procedures for these functions performed through VGM. This chapter provides procedures for customizing formats through the command line interface.

The following functions are provided:

• Creating formats. If the application environment requires constant switching between

video outputs, for example, you can build your own library of customized formats that individually select which video output is driven via the proper setting of AVST and DVST parameters.

• Editing the Format knob list. You can edit the Format knob list to include any

combination of built-in and user-defined formats. The default operating mode of the 802 uses the Format knob to select formats from a list of built in formats.

• Creating aliases. You can assign your own names to formats using aliases.

54 Chapter 4 Working with Formats

Format library

The generator has a built-in library of formats. The same format library is used for all 802 models. The formats are stored in read-only memory (ROM) along with the generator’s operating code.

Compatibility

Some formats are for displays and graphics systems that may not be compatible with a specific generator model. Attempting to load an incompatible format will give you an error message. If a format has too high of a pixel rate, a modified version of the format can be created with reduced horizontal timing parameters that bring the pixel clock rate below the limit of the generator. The horizontal and vertical rates however are correct. This lets you light-up a display and verify most of its operation. These modified formats can be created through the FMTJ command which references a global parameter (JRAT) that determines the bandwidth of the generator.

802BT/802R Video Test Generator User Guide 55

Format naming conventions

The names used in the built-in format library have been updated for the generator. Many format names on previous versions of the 802 generators have been renamed to more closely match the naming conventions used in the display industry or in the appropriate standards. There are three sets of naming conventions described in this section: 1) Composite television formats, 2) Component television formats, and 3) Computer display formats. In addition, several miscellaneous naming conventions are also described.

Composite television format names

Composite television formats apply to RF, D2, CVBS, and S-VIDEO signal interfaces. Composite television format names consist of a three to five character color coding scheme indicator followed by optional characters that indicate format adjustments.

Example

Color coding schemes

•NTSC

•PAL

• SECAM

Adjustments to the format

• 4x == sampling rate is four times the color sub-carrier frequency

• 44 == NTSC with color sub-carrier frequency of 4.43361875 MHz (as opposed to 3.58)

• # == sampling rate is reduced in order to make pixels square

• jp == NTSC-Japan (NTSC without 7.5 IRE setup)

• -M == PAL with 3.57561149 MHz color sub-carrier and M timing (M/PAL Brazil)

• -N == PAL with 3.58205625 MHz color sub-carrier (N/PAL Argentina, Paraguay, Uruguay)

• -N == NTSC color encoding with N timing (NTSC-N)

• -60 == PAL format that allows NTSC tape playback on PAL TV (PAL-60)

• plusKKKK == Enhanced wide-screen PALplus TV transmission system

• p == progressive video game signal (for example, NTSCp or PALp)

56 Chapter 4 Working with Formats

Common composite TV formats with sub-carriers and their respective standards:

• NTSC - ITU-R BT.470-6

• NTSC# - SMPTE 170M

• NTSC#KA - SMPTE 170M

• PAL - ITU-R BT.470-6

• PAL# - ITU-R BT.470-6

• SECAM

Component television format names

Component television formats are named by their vertical resolution and scanning method. These formats apply to RGB, YPbPr, YcbCr and HD-SDI video. In component television format naming, the first three or four characters indicate the active vertical lines in the format, the next characters indicate the frame tracing method, and the last two optional characters indicate the frame rate.

Example:

i2x480 29

Active

Using legacy format names

You can configure the generator to display names using conventions from older generator models.

Important: Configuring the generator to use legacy names will delete all user-defined video formats currently stored in the gener ator. T herefore, it is important to back u p the user data files from the generator to disk and then restore them bac k to the gener ator . V GM can be used to backup the generator.

To display legacy format names:

1. Turn the generator off.

2. Hold down the G key, and then power on the generator.

The following message appears on the front panel LCD.

3. Release the G key. This setting is retained throughout subsequent power cycles.

To re-assert the default format names you must reinitialize the generator:

1. Turn the generator off.

2. Hold down the ACS and DSS keys and then power on the generator.

The generator responds with the information in sequence as shown below:

640;480;800;2

62 Chapter 4 Working with Formats

Creating custom formats

You can create new signal formats for the generator and add them to non-volatile memory. You can create formats through VGM or by using a command line interface (either the RS-232 port or the IEEE-488 port). The recommended procedure for creating new formats is to use VGM. VGM contains the algorithms for ensuring compatibility between format parameters where there are dependencies in their respective values. Please refer to the VGM online help for information about creating formats using VGM.

Determining the signal specifications of the display

Your custom format will be based on the specifications of the display under test. Typically, you can find the information required for the format in the detailed specification sheet for the display. At a basic level, you must determine if you are working with an analog or a digital display. An analog display can show an endless range of colors or shades of gray. Analog displays normally accept video signal levels in the 1 Vp-p range. Digital displays are more limited and can display only a few gray levels or a limited number of pre-defined colors. These displays normally accept TTL video signals in the 4 Vp-p range.

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. When using this method, you can save the new format under a new name or the existing name.

Independent of the method you choose, you can enter each command interactively or, using your computer, create a text file containing all the commands you want to issue, and then download the text file to the generator. For instructions on creating and downloading text files, see “Sending commands from text files” on page 16.

Creating a new format

The FMTN command is used in creating a new format. This command sets all of the format parameters to known, default values. For a list of the parameters and their default values, see “FMTN” on page 331. Use the following procedure to create a new format using interactive commands.

802BT/802R Video Test Generator User Guide 63

To create a new format:

1. Establish a terminal session with the generator. See “Setting up a terminal connection

with the generator” on page 14.

2. Enter the following commands to initialize all parameters to default values and begin a format editing session:

FMTN // initializes all parameters to default values FMTB // begins a format editing session

3. Enter the format parameter commands in sequence to set the values for the new format.

HRES 654 // sets the horizontal resolution to 654 pixels

. . // other format parameters .

HTOT 720 // sets the horizontal total to 720 pixels

Note: You do not need to enter a parameter value if it matches the FMTN default setting.

4. End the editing session and save the new format using the following commands:

FMTE // ends a format editing session FMTA new_fmt_name // saves format as new specified name

5. Assign the format to the knob list using the following commands:

DIRL FMT // loads format directory into edit buffer DIRB // begins a directory edit session NAMI 20 new_fmt_name // assigns format to format knob list at 20 DIRE // ends a directory editing session DIRS // saves contents of directory as current name

Creating a format based on an existing format

Use the following procedure to create a format based on an existing format using interactive commands.

To create a custom format based on an existing format:

1. Determine the signal specifications of the display under test and select an existing format in the generator’s format library whose parameter values are similar.

2. Connect the display to the generator.

3. Using the Format knob, select the format you want to use as a template for the new format.

4. Using the Image knob, select the Format image to view the parameters of the selected format.

5. Establish a terminal session with the generator.

64 Chapter 4 Working with Formats

6. Enter the following commands to load and begin editing the existing format.

FMTL format_name // loads existing format into the format editor FMTB // begins a format editing session

7. Enter the format parameter commands in sequence where the new values differ from the existing format values. For example to modify the horizontal resolution enter the following command:

HRES 654

Note: You do not need to enter parameter values if they match the existing format.

8. End the editing session and save the new format using the following commands:

FMTE // ends a format editing session FMTA new_fmt_name // saves format as new specified name

9. Assign the format to the knob list using the following commands:

Modifying existing formats

The following procedure demonstrates how to modify the parameters of an existing format using the command interface. This example changes an existing digital format from RGB 4:4:4 to YCbCr 4:2:2, and saves the format into the default format directory.

To edit an existing format:

1. Establish a terminal session with the generator.

2. Set the generator to digital friendly mode:

SROP 2 (or SROP 2 4) // sets generator to digital friendly mode SROP 8 // sets generator to status display mode

3. Load and begin editing the format:

FMTL existing_format // loads existing format into format editor FMTB // begins a format editing session

4. Enter the format parameter commands in sequence where the values differ from the default values. For example to modify the component video type enter the following command:

DVST 14 // changes the component color to YCbCr DVSM 2 // changes component color make up to 4:2:2 ALLU // loads hardware and outputs new signal

5. End the editing session and save the format using the following commands:

FMTE // ends the format editing session

802BT/802R Video Test Generator User Guide 65

FMTA new_fmt_name // saves format as new specified name

6. Assign the format to the knob list using these commands:

DIRL FMT // loads format directory into edit buffer DIRB // begins a directory edit session NAMI 20 new_fmt_name // assigns new format to format knob list at 20 DIRE // ends a directory editing session DIRS // saves contents of directory as current name

7. Load the new format using these commands:

FMTL new_fmt_name // loads new format in edit buffer FMTU // applies new format to the generator

66 Chapter 4 Working with Formats

Editing Format knob lists

Stepping through all of the available formats using the Format knob 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 802 to show only the formats you want, in the order you want, when you turn the Format knob. The 802 maintains a list of these formats in non-volatile memory, and you can edit the list to include formats you have created and to remove any unneeded formats. You can edit the Format knob list using the internal editor or the command line interface; however, the most convenient way to edit the list and create custom knob lists is through VGM. Please refer to the VGM online help for instructions on creating and editing format knob lists.

The default Format knob list is named fmt. In addition to editing this list, you can also create new lists and name them to reflect their uses at your site.

Editing format knob list using internal editor

Use the following procedures to edit the format knob list using the internal format editor.

To edit the format knob list:

1. Power-up the generator while holding down the Image key until programmer is displayed.

2. Select the FmtList image.

802BT/802R Video Test Generator User Guide 67

3. Press the Step key to start the Format List editor.

The left side of the screen shows the current contents of the format list. The formats appear in the order that they are selected by the Format knob during normal operation.

The right side of the screen shows the available formats.

4. Use the Format and Image knobs to select formats in the lists. Use these commands to edit the format list.

Key Function

Insert (DCS) Inserts the format selected from the list of available files at the cursor

position in the format list.

Delete (B) Remove the selected format from the format list.

Move (R) Moves the selected format in the format list to another position in the list.

To move the selected format, press Move, use the Format knob to specify the target position, and then press the Move key again.

Remove (DSS) Deletes the format selected in the list of available formats. This will

erase the entire contents of the file from non-volatile memory. Since this operation can destroy a lot of programming work, an on-screen message will ask you to confirm the removal of the file. Pressing the Yes or OK key will erase the file. Pressing the No or Cancel key will abort the removal operation.

5. Press the Exit (Step) key to save the edited list and exit the editor.

Editing format knob list using command line interface

Use the following procedures to edit the format knob list and create new knob lists through the command line interface.

To insert a format at a specific location in a format knob list:

1. Establish a terminal session with the generator.

2. Create a format and save it to the generator (see “Creating custom formats” on page

63.)

3. Enter the following commands:

DIRL fmt // loads default format list (fmt) DIRB // begins a directory editing session NAMI 257 MyFormat // inserts format named MyFormat at position 257 DIRE // ends the directory editing session DIRS // saves contents of directory as current name

To remove a format from a specific location in the format knob list:

DIRL fmt // loads default format list (fmt) DIRB // begins a directory editing session NAMK MyFormat // deletes format named MyFormat DIRE // ends the directory editing session DIRS // saves contents of directory as current name

To create a new format knob list, enter the following commands:

DIRL fmt // loads default format list (fmt) DIRB // begins a directory editing session NAMK format_1 // deletes format_1

. . // deletes other formats .

NAMK format_x // deletes format_x NAMI 1 new_format_1 // inserts new_format_1 at location 1

. . // insert other formats .

NAMI x new_format_x // inserts new_format_x at location x DIRE // ends the directory editing session DIRA new_fmt // saves new format list as new_fmt

To apply a new format knob list:

FMTP new_fmt // loads format list new_fmt

Topics in this chapter:

• Overview

• Creating custom images

• Downloading bitmap images from a PCMCIA card

• Looping through images

• Editing Image knob list

• Creating image aliases

802BT/802R Video Test Generator User Guide 73

Overview

The 802R/BT includes a library of 250 test images. In addition, you can create custom images, which consist of one or more drawing primitives, including single pixel dots, lines, rectangles, and ovals. You can select the grayscale and color tables used in the image and save the images in non-volatile memory. Custom images can be added to the list of built-in images that can be selected with the Image knob. You can create and edit test images and edit the Image knob list using the Video Generator Manager (VGM) application or the command line interface. Please refer to the VGM online help for details on creating custom images using VGM.

The following functions are provided:

• Creating images. You can create your own custom images and add them to the image

library.

• Downloading bitmap images. You can also create your own images in other

applications and save them as bitmap files which can then be downloaded using a terminal emulator or from a PCMCIA card.

• Editing the Image knob list. You can edit the Image knob list to include any

combination of built-in and custom images. The default operating mode of the 802 uses the Image knob to select images from an internal list of built-in images.

• Setting up a looping image display. You can set up a continuous cycling mode that

draws images one-after-another in an infinite loop. Image looping can be used for burn-in testing or for running single-mode displays at trade shows.

• Creating aliases. You can assign your own names to images using aliases.

Viewing the image list

You can view the list of images available in the generator using VGM or the command line interface. Please refer to the VGM online help for details on viewing the image list using VGM. Use the following procedure to view the image list using the command line interface.

To display the image list :

1. Establish a terminal session with the generator. See “Setting up a terminal connection

with the generator” on page 14.

2. Load the default image directory (img) or custom image directory by entering the following command:

DIRL IMG

3. List the contents of the image directory by entering the following command:

NAMQ? 1 200 // lists the images from the first through 200

74 Chapter 5 Working with Images

Creating custom images

This section describes how to create images and add them to the generator’s image library, and how to customize the image list. The recommended method for creating images is create a text file containing the commands for creating the image, and then downloading the text file to the generator. Another method for creating images is to use the Image Editor in VGM to create a basic image, save the basic image as a command file in VGM, and then open and edit the command file to refine the image as needed.

To create custom images with a command file:

1. Using a text editor, open a text file (command file) on your computer and enter the following commands.

OUTG 0 // gates all video and sync outputs off IMGN new_image // creates a new image IMGB // begin an image editing session XRES 640 // sets the horizontal resolution YRES 480 // sets the vertical resolution

. . // other image parameters .

IMGE // ends an image editing session IMGA new_image // saves image as new_image

OUTG 1 // gates all video and sync outputs on

IMGU // draws the image ALLU // applies the buffer to the generator hardware

2. Save the text file, using a *.txt extension.

3. Establish a terminal session with the generator. See “Setting up a terminal connection

with the generator” on page 14.

4. At the R:> prompt, transfer the text file to the generator. For example, to transfer a file using HyperTerminal, do the following:

a. On the Transfer menu, click Send Text File. The Send Text File dialog box

appears.

b. Select the text file you want to send, and then click Open. HyperTerminal displays

the commands as they are sent.

c. Press Enter once to ensure that the last command is sent.

5. Assign the image to Image knob list by entering the following commands:

DIRL IMG // loads image directory into edit buffer DIRB // begins a directory editing session NAMI 20 new_image // assigns image to image knob list at 20 DIRE // ends a directory editing session DIRS // saves contents of directory as current name

Downloading bitmap images from a PCMCIA card

This section describes how to store a bitmap image on a standard PCMCIA memory card, and then load the image as you would a built-in image. The generator can load only one image from a card. Although you can download an image using VGM, loading an image from a card is faster and easier.

This feature is supported on 802BT and 802R generators with video board FPGA 91 or later, DVI daughter card FPGA 0xE3 or later, and firmware 7.3834000 or later (802BT) or

7.38180000 or later (802R). To determine your generator specifications, “Displaying

system information” on page 44.

To copy an image onto a card:

1. Save the image you want to store on the card as an 8-bit or 32-bit (24-bit TrueColor) bitmap (.bmp) file on your computer using any file name.

2. Hold down the ACS, DCS, and DSS keys, and then cycle the power to the generator. This removes any special modes and sets the baud rate of the serial port to 2400 bps.

3. Establish a terminal session with the generator and change the baud rate of the generator to 38400 bps (see “Changing the baud rate” on page 15.)

4. Insert a PCMCIA card into the slot in the generator.

5. At the R:> prompt, enter the following command to initiate the YMODEM-BATCH file-upload protocol:

YMDI

6. At the R:> prompt, transfer the file to the card. For example, to transfer a file using HyperTerminal, do the following:

a. On the Transfer menu, click Send File. The Send File dialog box appears. b. In the Filename box, click Browse and select the bitmap file you want to copy to

the generator.

c. In the Protocol box, click the down arrow and select Ymodem. d. Click Send.

Note: You must send the image within about 15 seconds after sending the YMDI command. If the R:> command prompt appears before you send the image, send the YDMI command again, and then send the image again.

For descriptions of any error codes displayed, see Appendix C, “Error Messages.”

To view an image stored on a PCMCIA card:

1. Insert the card that contains the image you want to view.

78 Chapter 5 Working with Images

Note: The card you need is a Type 1, Battery Backed RAM PCMCIA card with at least

2 MB of storage. These cards are available from synchrotech P/N PCM-SRW-AM002 2MB. Flash or compact type memory cards will not work.

2. Use one of the following procedures to configure the generator to use a format with the same pixel depth as the image:

• Select a built-in format with the appropriate pixel depth.

• Create a format with the appropriate pixel depth.

• Establish a terminal session with the generator and enter the following commands

to set the pixel depth to 32-bit (24-bit TrueColor) or 8-bit:

PELD 32; ALLU

PELD 8; ALLU

• Hold down the R key while pressing and releasing the G key to toggle the pixel

depth between 8 and 32-bit pixel depths.

3. Using the Image knob, select the CardBMP image, or enter this command:

IMGL CardBMP; ALLU

The image appears on the display.

4. To view an image from a different card, switch the cards, and then re-select the CardBMP image.

802BT/802R Video Test Generator User Guide 79

Looping through images

You can set up a continuous cycling mode that draws all images in the image knob listone-after-another in an infinite loop. When activated, the message “Loop Enabled” appears on the display under test.

To enable image looping:

1. Using the Format knob, select a format compatible with the display under test.

2. Turn the Image knob clockwise beyond the last image in the Image list about one turn.

The message “Loop Enabled” appears on the display under test. After a second or two, the first image in the cycle appears and the generator continuously cycles through the test image list using a given format in this mode.

To disable image looping:

1. Turn the Image knob counter-clockwise to stop image looping.

80 Chapter 5 Working with Images

Editing Image knob list

If your test environment requires only a subset of the available built-in images, you can configure the 802 to show only the images you want, in the order you want, when the Image knob is turned. The 802 maintains a list of these images in non-volatile memory. You can edit this list to include images you have created and to remove unneeded images. The Image knob list can be edited using the command line interface; however, the most convenient way to edit the knob list and create custom knob lists is using VGM. Please refer to the VGM online help for procedures on editing image knob lists.

The default Image knob list is named img. In addition to editing this list, you can also create new lists and name them to reflect their uses at your site.

Editing image knob list using internal editor

802BT/802R Video Test Generator User Guide 85

Overview

When testing video displays, you typically select a format using the Format knob, and then select an image using the Image knob. In a production environment, where there might be a need to test several combinations of formats and images, you can create a test sequence to automate the process of selecting formats and images. Test sequences provide a way to progress through a pre-defined sequence of format and images, either manually or automatically.

You can create test sequences using the command line interface, the internal sequence editor or the Video Generator Manager (VGM) application. This section describes how to create and run test sequences using the command line interface and internal sequence editor. Please refer to the VGM online help for instructions on defining and running a test sequence from VGM.

The following functions are provided:

• Create your own custom test sequences consisting of multiple steps. Each step specifies the format and image to display as well as the duration of the step. You can create multiple sequence files, which are stored in non-volatile memory.

• Program the 802R/BT generator to run in test-sequence mode on power-up. This mode of operation is useful in a manufacturing test environment where the same test procedure must be repeated on many identical displays. Multiple test sequences can be stored in the generator and selected by the operator.

86 Chapter 6 Working with Test Sequences

Creating a test sequence

You can create a test sequence using the command line interface, the generator’s built-in editor or VGM.

Creating a test sequence using command line

You can develop test sequences either by entering command interactively through a terminal session or by entering a series of commands in a text file and then send them to the generator through hyper terminal. When developing long test sequences, the recommended procedure is to enter commands in a text file, and then send the file to the generator. This approach enables you to change the test sequence without entering the entire command script.

Use the following procedure to create a test sequence, save it to the sequence directory, and then run it using the command line interface.

To create and save a test sequence interactively using the command line interface:

1. Establish a terminal session with the generator.

2. Enter the following commands to create a three-step sequence named MySeq.

SEQN // initializes the sequence edit buffer SEQB // begins a sequence editing session STEP 1 // selects a step to be edited SDLY 5.0 // sets the delay for the current step to five seconds FMTL 480p59 // loads a format IMGL SMPTEbar // loads an image STEP 2 // selects a step to be edited SDLY 5.0 // sets the delay for the current step to five seconds FMTL 720p60 // loads a second format (same image) IMGL Outline1 // loads an image STEP 3 // selects a step to be edited SDLY 5.0 // sets the delay for the current step to five seconds FMTL 1080i29 // loads a third format IMGL Geom_4 // loads another image SEQE // ends the sequence editing session SEQA MySeq // saves the current contents of the sequence editor

To create and save a test sequence from a text file:

1. Using a text editor, open a text file (command file) on your computer and enter the

following commands to create a three-step sequence named MySeq.:

802BT/802R Video Test Generator User Guide 87

IMGL SMPTEbar // loads an image STEP 2 // selects a step to be edited SDLY 5.0 // sets the delay for the current step to five seconds FMTL 720p60 // loads a second format (same image) IMGL Outline1 // loads an image STEP 3 // selects a step to be edited SDLY 5.0 // sets the delay for the current step to five seconds FMTL 1080i29 // loads a third format IMGL Geom_4 // loads another image SEQE // ends the sequence editing session SEQA MySeq // saves the current contents of the sequence editor

2. Save the text file, using a *.txt extension.

3. Establish a terminal session with the generator.

4. Transfer the text file to the generator. For example, to transfer the file using HyperTerminal, do the following:

a. On the Transfer menu, click Send Text File. The Send Text File dialog box

appears.

b. Select the text file you want to send, and then click Open. HyperTerminal displays

the commands as they are sent.

c. Press Enter once to ensure that the last command is sent.

To insert a sequence at a specific location in the sequence list:

1. Establish a terminal session with the generator.

2. Enter the following commands:

DIRL seq // loads sequence directory into edit buffer DIRB // begins a directory editing session NAMI 1 MySeq // assigns sequence to sequence list at 1 DIRE // ends the directory editing session DIRS // saves contents of directory as current name

Creating and editing test sequences using the internal editor

You can use the generator’s internal Sequence Editor to create, edit and run test sequences without using VGM. The 802 can be configured to allow an operator to run only certain sequence files in the sequence mode. The 802 maintains a list of these accessible sequences in non-volatile memory. You will need to edit the list if you wish to add sequences you have created. The procedures for creating and editing the sequence file list are provided below.

To create a test sequence using the internal sequence editor:

1. Turn on the generator while pressing the Image key until programmer is displayed.

2. Select the SeqList image.

88 Chapter 6 Working with Test Sequences

3. Press the Image key to start the Sequence List editor.

4. Use the Image knob to select a sequence file from the list of available files. NewSeq is provided by default to serve as a template.

5. Press the Insert key (DCS) to insert the NewSeq file into the sequence list.

6. Use the Format knob to select the NewSeq file, and then press the Modify key.

7. Use the Format knob to select the field you want to edit. Use the Image knob to select field values.

Press Change (Outputs) to apply the selected value.

Press Insert (ACS) to insert a new step.

Press Clear (G) to delete all steps.

Press Delete (B) to delete the selected step.

To move the selected step, press Move (R), then use the Format knob to select the target position, and then press Move again.

8. Press Mode (DSS) to specify how the generator should run the sequence file when the generator is started. If you have multiple sequence files, the file with the most recent mode setting you make will apply upon startup. Setting the mode for a file will

deactivate the mode status of all other sequence files. If a start-up mode is not set for any sequence file, then the generator will start in the normal operating mode.

Mode Display option Description

blank If no mode is specified the sequence is not started when the

generator is started.

step Use the Image knob to advance through sequence steps.

You cannot advance past the last step. However, rotating the Image knob forward one revolution past the last step will change the mode to automatic. Rotating the Image knob backward one revolution changes the mode back to manual.

Step information is displayed on the LCD only.

9. Press Save (DCS) to save the sequence file. Use the Format and Image knobs to specify a name for the file by selecting the characters presented.

10. Press Exit (Image) to exit the Sequence Editor, and to return to the Sequence List editor.

To edit the list of sequences that can be used:

1. Hold down the Image key while starting the generator, until programmer is displayed.

2. Select the SeqList image.

3. Press the Image key to start the Sequence List editor.

The Sequence List box shows a list of sequence files that can be selected with the Format knob. The Available Files box shows all sequence files available.
