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.
2 Chapter 1 Getting Started
• High Bandwidth Digital Content Protection (HDCP). Generates HDCP encrypted
content for testing DDCP-compliant displays.
• DVI or HDMI Analyzer. Optional receiver, which measures pixel errors at different
frequencies, measures timing of external sources, and displays EDID from external
sources. Can also be used to test cables or distribution systems.
• High Definition Multimedia Interface (HDMI). The HDMI feature helps manufacturers
increase the likelihood that their products will not only meet compliance standards, but
also flawlessly interoperate with other HDMI devices.
• General Purpose Interface Bus (IEEE-488). Use to operate the generator in an
automated environment.
• Component video BNC connectors. The generator can be equipped with R, G, B,
VS, and HS/CS BNC connectors.
802BT/802R Video Test Generator User Guide 3
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.

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.

Special operating modes
You can set the generator to operate in various modes to accomplish specific functions.
When any special operational mode is set, it persists (until overridden) throughout
subsequent power cycles, which may be performed to set other modes.
You can view the operational settings and special functions of the generator on a video
display by viewing the GenOps image. This image provides key sequences and the status
of special operating modes in the generator.
To determine the status of operating modes:
1. Connect the appropriate interface cable to the video display.
2. Using the Format knob, select a format suitable for the display.
3. Turn the Image knob to select the GenOps image.
