Calibrating  
Model 700 and 701 generators use programmable hardware to set the amplitude calibration factors  
for analog video outputs. These calibration factors are stored in Flash EPROM, and are not lost if the  
batteries are run down or removed.  
Quantum Data calibrates the analog video and sync output amplitudes in new generators to pub-  
lished specifications. You can recalibrate these amplitudes over a nominal range to meet your  
specific testing conditions.  
WARNING: Recalling the original factory calibration settings is not possible after saving  
your own settings.  
Equipment Needed for Calibration  
DC voltmeter capable of measuring from 0 to 1 volt with a minimum resolution of 2 millivolts  
Precision 75 ohm (+/- 1%) input terminator for the voltmeter  
Test cable to connect the voltmeter to the R, G, B and ground pins on the VGA connector  
Oscilloscope with a precision 75 ohm (+/- 1%) input impedance and suitable gain and band-  
width to display a 1.00 Volt pk-pk signal with 3.579 MHz color carrier

Special Tests  
Using Generator with CS-1 Probe  
The Test > CS1 Probe option uses the Quantum Data CS-1 color sensor to measure the chromaticity  
and luminance (brightness) of a display. The CS-1 probe connects to the generator’s serial port.  
Chromaticity is shown as x,y C.I.E. coordinates and the luminance (Y) can be shown either in units of  
foot-Lamberts or nits. The CS-1 needs to be over a fully lit white area of the display for accurate  
readings. The Flat_Wht test image is suitable for use with the CS-1

Testing HDCP Interfaces  
Model 701 video test generators may be equipped with an optional production (private) key for testing  
High-bandwidth Digital Content Protection (HDCP) interfaces of DVI receivers that support HDCP. For  
more information about HDCP, see http://www.digital-cp.com/.  
To output HDCP-encyrpted video content:  
1. Connect the DVI connector of the generator with the DVI connector of the device under test.

Model 700, 701 Quick Start Guide  
 
Special Tests  
2. Choose a DVI video format supported by the device.  
3. Press Test > HDCP > Start to output HDCP encrypted content.  
The display on the generator indicates if the test passed or failed. If the test passed, the currently  
selected pattern is displayed on the device under test. Noise is displayed if the HDCP authenti-  
cation failed.  
After the initial authentication of the connection is established, the generator displays the number  
of authentication verficiation cycles until you stop the test.  
During the test, if you reconnect the cable or restart the device under test, the test should restart  
automatically.  
4. To stop the test, press the Exit soft key or any gray key.  
Generating Pseudo Random Noise  
When the generator is connected to a device that supports the Quantum Data pseudo random noise  
standard, press Test > PR Noise to output the noise pattern as a static image. Depending on how the  
device is designed, it may compare the pattern output by the generator with an identical pattern,  
created internally, to detect errors in the cable and in the device itself.

Using Video Generator Manager  
About VGM  
Video Generator Manager (VGM) is a Windows-based application for creating and editing formats and  
test sequences. As many as 132 formats and one test sequence can be stored in the generator.  
VGM was originally created for use with Quantum Data 80x video generators. The 700-Series  
generators support only some VGM features. For information about using VGM, see the VGM help file.  
VGM Quick Tour  
1. Connect the generator to your computer using a null modem serial cable.  
Note: You may not be able to connect to the generator when it is Power Save mode.  
2. Start VGM, and then select Generator > Connect.  
3. In the Select Port dialog box, select the Serial option, and then click OK.  
The name of the connected generator is listed in the bottom half of the VGM window.  
4. Click the View Formats icon  
to view the formats available in the generator, and then double-  
click the format you want the generator to use.  
5. Click the  
Image List icon to view the available images, and then double-click the image you  
want the generator to use.

Model 700, 701 Quick Start Guide  
 
Creating Video Formats  
Editing Video Formats  
You can use VGM to create your own video formats. You can start with a default format in the VGM  
format editor, or copy an existing format.  
To create a video format:  
1. Connect the generator with VGM, and then double-click the generator name.  
2. Click the View Formats icon to list the available formats.  
3. Right-click a format that is similar to the format you want to create, then select Copy to create a  
copy of the format. The name of the new format is based on the original format, followed by an  
underscore and number.  
4. Right-click the copied format, select Edit, and then click Yes to open the Format Editor.  
5. Specify the format parameters.  
The format editor works as described in the VGM help file, except that the physical size entries  
have no affect on how test images are displayed on the 700 series. However, the integer portion  
of the horizontal size in millimeters specifies the storage location of the format in the generator.  
Unlike our other models, the 70x generators store formats by specific numeric locations, and not  
by name. If you do not change this number, the edited format will replace the previous version of  
the format when you upload it back to the generator. You will not get any warnings that you are  
about to overwrite a memory location.  
6. Select File > Save to save the format on your PC, and then close the Format Editor window.  
7. In the VGM data pane, select the format, and click the Send Data icon  
the generator.  
to store the format on

Modifying Test Sequence  
Editing the Test Sequence  
The generator has a default sequence, which you can edit in VGM. One sequence can be stored in  
the generator at the same time.  
To modify the test sequence:  
1. Connect the generator with VGM, and then double-click the generator name.  
2. In the generator window, click the Sequence List icon  
to display the sequence name.  
3. Right-click the sequence name, and then select Edit to open the Sequence Editor.  
4. Select the 70x generator from the Generator list. Do not select the virtual generator.  
5. Modify the test sequence.  
VGM help describes the basic operation of the Sequence editor. Specify only a format and image  
for each step. Do not use the No Change value. The 700-Series generators do not support the  
output gating and sync options, and the No Change value.  
6. Select Edit > Edit Sequence Name to save the sequence as a new sequence file.  
7. Select File > Save to save the sequence on your PC, and then close the Sequence Editor.  
8. In the top half of the main VGM window, select the sequence, then click the Send Data icon  
to store the sequence on the generator.  
To run the test sequence, see page 12.

Pattern Descriptions  
Flat_Wht/(R,G,B)  
Description - Fills the screen with white, blue (B), green (G) or red (R).  
Application - Use to test chrominence.  
Grid  
Decription - White crosshatch on a black background. The lines form square boxes. A single pixel dot  
is located in the center of each crosshatch box.  
Application - Use the Grid pattern to test convergence. To accurately produce an image on a color  
monitor, the three electron beams in the CRT must meet (converge) at the same location at the same  
time. Lines displayed on a misconverged monitor appear as several multi-colored lines, and the  
transitions between different colored areas contain fringes of other colors.  
Rev_Grid  
Description - Black crosshatch drawn on a white background. The lines form square boxes.  
Application - Use to test convergence. To accurately produce an image on a color monitor, the three  
electron beams in the CRT must meet (converge) at the same location at the same time. Lines  
displayed on a misconverged monitor appear as several multi-colored lines, and the transitions  
between different colored areas contain fringes of other colors.  
Overscan  
Description - The image has three parts. The first part consists of five white circles. A large circle is  
drawn in the center of the screen. Its diameter equals the lesser of the video height or width of the  
display. A circle also is drawn in each of the corners of the screen. The diameter of the corner circles  
equals one-fifth of the display width.  
The second part of the image consists of a white crosshatch. The number of boxes in the crosshatch  
depends on the physical size of the display.  
The last part of the image consists of white tic marks on the horizontal and vertical center lines of the  
image. The marks are one pixel thick. Every other mark is slightly longer. The color of the pattern can  
be changed with the individual video output controls.  
Application - Used for detecting non-uniformity and non-linearity. The image presents an undistorted  
display, the horizontal and vertical sweeps of the electron beam across the face of the CRT should be  
at uniform speeds. Any non-uniformity in the sweep causes portions of an image to stretch while  
other portions are compressed. Non-linearity in a monitor shows up in several ways. It may be  
19  
 
Pattern Descriptions  
present across the entire screen, in a large portion of the screen, or localized in a very small area.  
Raster  
Description - Black display (nothing being displayed).  
Application - Useful for centering the raster on a CRT. Many monitor applications require that the  
displayed image or text fit completely within a bezel that surrounds the CRT. This usually requires that  
you first center the blank raster on the face of the CRT, and then center the image within the raster.  
Cutoff  
Description - The entire active video area is filled with a shade of gray.  
Application - Useful for testing chrominence and contrast.  
Window  
Description - Single white box in the center of active video. The size of the box is one-third the width  
and height of the active video area.  
Application - Use for brightness control adjustment.  
Focus  
Description - This image fills the screen with white M characters.  
Application - Used for testing focus.  
ColorBar  
Description - The image has 7 full-height vertical color bars.  
Application - Useful for verifying that none of the video channels are bad or connected incorrectly.  
GrayBar  
Description - The image has 16 full-height vertical graybars. The intensity of the bars iincreases from  
left to right. All bars are untined gray at all levels.  
Application - Useful for testing brightness control adjustment and brightness uniformity tests.  
20  
Model 700, 701 Quick Start Guide  
 
Pattern Descriptions  
Regulate  
Description - The image has a pair of white outlined boxes which surround a blinking solid white box.  
Application - Tests for proper high voltage regulation.  
Checker  
Description - The image’s active video area is equally divided into a 6x6 checkerboard of black and  
white boxes.  
Application - The pattern is based on a proposed ANSI method of measuring the contrast ratio of  
video projection systems.  
Dot_12  
Description - The image’s active video area is filled with multiple rows of white, single pixel dots. The  
dots define the corners of what would appear to be square boxes if all connecting pixels were lit. The  
number of rows of boxes and the number of boxes per row depends on which version of the image is  
selected and the screen aspect ratio of the currently-loaded format.  
Application - Used to measure convergence. To accurately produce an image on a color monitor, the  
three electron beams in the CRT must meet (converge) at the same location at the same time. Small  
dots displayed on a misconverged monitor appear as a group of multi-colored dots.  
SMPTEBar  
Description - The image’s upper 67% of the image consists of a series of color bars. These bars  
match the order of the bars in the SMPTE and EIA patterns.  
The left side of the lower 25% of the image contains isolated -I and Q color difference signals that  
match the original EIA and SMPTE patterns. The -I signal appears as a bluish-gray bar and the Q  
signal appears as a purple bar on a TV monitor. The bars are separated by a white (+100 IRE) bar.  
After the Q blocks there are four blocks: black, (black - 4 IRE), black, (black + 4IRE).  
The right side of the lower 25% of the image contains a narrow 12.5 IRE gray bar.  
Application - Designed for adjusting the color settings of a television monitor by eye. It can also be  
used with a TV waveform analyzer and vectorscope for testing video signal processors and color  
decoders.

Pattern Descriptions  
Ramp  
Description - This image provides an active video area starting from full black (+7.5 IRE for NTSC) at  
one edge of the screen to full white (+100 IRE) at or near the opposite end of the screen.  
Application - Useful for testing pixel anomolies and chrominance.  
PulseBar  
Description - The image looks like two vertical lines followed by a wide vertical bar on a display’s  
screen. The first line is a red pulse. The pulse is 20 T for PAL and 12.5 T for NTSC formats. The  
second narrower line is a 2 T white sine-squared pulse. T = 100 nSec for PAL and 125 nSec for  
NTSC formats. The wide bar is white with sine-squared edges.  
Application - This image is intended for TV formats, but can be displayed with any format up to 100  
MHz.  
Burst  
Description - The left side starts with reference white and black levels. This is followed by six bursts  
of square waves. Each burst is at a different frequency, forming vertical lines of various widths. The  
frequencies, going from left to right, are 0.5, 1, 1.53, 2.04, 3.06 and 6.13MHz.  
Application - The image can also be used with a TV waveform analyzer to check the frequency  
response of a video system. One scan line of the image, as it would appear on a waveform analyzer.  
High frequency roll-off (loss) would show up as a decrease in the peak-to-peak swings on the right  
side of the waveform. Low frequency roll-off would show up as a decrease in the peak-to-peak  
swings on the left side of the waveform.

Updating Firmware  
Updating Firmware  
The generator’s operating system firmware is stored in Flash EPROM, which you can update via the  
serial port.  
To install a firmware update:  
1. Turn off generator, and connect it to your PC using a null modem serial cable.  
2. Hold down the upper-right menu button, and then press the On/Off button. The LCD screen will  
indicate that the generator is ready for the upload.  
Pressing the upper-right button during startup sets the serial port at 19200 bps. To set the serial  
port at 9600 bps, press the upper-left button while turning on the generator.  
3. If necessary, expand the .zip archive file that contains the firmware update.  
4. If you have HyperTerminal, double-click the HyperTerminal setup file (QD70x Upgrade.ht) to start  
HyperTerminal with the proper communications setup (9600 bps, 8 data bits, no parity, 1 stop bit,  
Xon/Xoff flow control).  
Note: You may not be able to connect to the generator when it is in Power Save mode.  
If you are using a COM port other than COM1, choose File > Properties to select the desired COM  
port.  
HyperTerminal Private Edition is recommended when using Windows 2000 to install firmware.  
5. In HyperTerminal, select Transfer > Send Text File.  
6. In the Send Text File dialog box, double-click the firmware filename to start the transfer.  
The generator will display the progress of the update, which takes several minutes, and then  
restart to complete the installation. If you need to cancel the installation, select Exit.  
7. If the firmware update includes new or revised video formats, press Options > Clear Fmts, and  
then select Yes to delete the current formats. Then press Options > Reload Fmts to load the new  
formats.
