1. About the 980 DP Video Generator Module
This chapter provides an overview of features of the 980 DP Video Generator module and the 980 GUI Manager.
The module can be equipped in either of the following 980 Advanced Test Platforms:
1) The 980B Advanced Test Platform – 5-slot chassis with a 15 inch touch display
2) The 980R Advanced Test Platform - 5-slot rack mountable chassis with a 7 inch touch display
The 980 DP Video Generator module supports video pattern testing and audio testing of DP 1.2 capable displays
at 5.4Gb/s link rates per 4 lanes. It is equipped with two (2) Tx ports and an Rx port. The two DP Tx ports are both
active simultaneously which enables you to test multiple sinks and displays at the same time. The Rx port is for the
optional DP analyzer for testing DisplayPort source devices up to 5.4Gb/s link rates per 4 lanes.
The 980 GUI Manager is a PC application to manage and use the 980 DP Video Generator module.
1.1
Scope of this User Guide
This User Guide provides descriptive and procedural information on the 980 DP Video Generator module for
testing DP display devices.
Although you can operate the 980 DP Video Generator module through the “embedded GUI,” most of the
examples used in the procedures in this User Guide are taken from the external standalone PC 980 GUI Manager.
The procedures are nearly identical between the embedded GUI running through the 980B/980R front panel
display and the external standalone PC application but the look and feel is slightly different.
There are separate User Guides for the other 980B/980R modules. The following is a list of the User Guides
available with the 980B/980R and its modules. These are available from the downloads and product web pages of
the Quantum Data website http://www.quantumdata.com/products/980.asp:
The following is a list of the User Guides available for the 980 systems:

4. DP LINK TRAINING CONTROL
The 980 DP Video Generator module enables you to control the link training with a DisplayPort sink device. The
Link Train application enables you to control the link training process. There are two modes: 1) Adaptive Training
and 2) Non Adaptive training. Adaptive Training enables you to train based on Lane Count and Link Rates
capabilities that you define in the application. When you set the Lane Count and Link Rate in the Adaptive training
mode you are emulating a DP source with those capabilities. The link will be established with the appropriate
voltage swing level and pre-emphasis necessary to establish a proper link. In the Non-Adaptive mode, you are
forcing the Lane Count and Link Rate as well as the voltage swing level and pre-emphasis and bypassing the
typical link training function.
Note that you can monitor the Aux Chan link transactions during these link training tests.
4.1
Accessing the Link Training Control application
Use the following procedure to test link training with your DP display device. This procedure assumes that you
have already selected a DP VESA format and a test pattern to meet your test application requirements.
1. Access the Link Train control application through the Tools tab on the 980 DP Video Generator module
interface as shown below.
The Command tab is show in the example below.

5 Auxiliary Channel Analyzer (ACA) Utilities
The Auxiliary Channel Analyzer (ACA) utilities enable you to view the DDC and aux channel traffic for DisplayPort
1.2 streams in real time or from stored real time files. For DisplayPort, you can view the HDCP authentication
transactions, EDID exchanges and Link Training transactions in real time with the ACA either through the
embedded 980 GUI (or the external 980 GUI with release 4.9.35 or later). There are three (3) Auxiliary Channel
Analyzer utilities:

Auxiliary Channel Analyzer – Used for real time viewing auxiliary channel DisplayPort Aux Chan data
through the embedded 980 GUI Manager.

ACA Remote Control - Used for viewing auxiliary channel DisplayPort data through the external 980 GUI
Manager. This application operates in sync with the Aux Channel Analyzer on the embedded display.

ACA Data Viewer - Used for viewing previously captured auxiliary channel data. You can view saved
these ACA traces and disseminate them to colleagues at other locations. These colleagues can then use
the ACA Data Viewer utility off-line without a 980 test instrument to view these transactions.
The look and feel of each utility is somewhat different.

9. Command Reference
This section provides a list of commands available for use with the 980 DP Video Generator.
Since the 980 can be equipped with multiple modules, there is a convention for addressing commands to specific
modules. By default any command you enter will be addressed to the 980 DP Video Generator module in slot 3.
The addressing convention is as follows:
<IN/OUT><Slot><Port>: command_string
Here are some examples of addressing commands. The configuration used in these examples is a 980 DP
Protocol Analyzer module in the first slot (Slot 1) and the 980 DP Video Generator module in the third slot (Slot 3).
Example #1: Load a format (resolution) for the transmitter port (Tx1) on the 980 DP Video Generator module:
OUT30:FMTL SMPTEBar
Example #2: Query the image transmitted:
OUT30:IMGU?
Notes:
1. Text case is not important.
2. Since both Tx ports on the DP Video Generator module always transmit the same signal, you do not have to
include the port number.

Upgrading the 980 Manager and 980
This Chapter provides information about upgrading your 980 and 980 GUI Manager. Detailed procedures are not
provided in this document. Please be sure to refer to the Release Notes for a specific release for detailed
upgrade instructions.
Quantum Data periodically provides maintenance release of software and firmware. The most recent versions are
available on the downloads page of the Quantum Data website.
http://www.quantumdata.com/downloads/index.asp
Two software packages are available for upgrading the 980:
1. Embedded firmware and gateware package for the 980 instrument. This is a Debian software package for
installation in the Linux-based instrument. (The file extension is .deb.) This package also includes the
embedded Graphical User Interface that will be installed for the Touch Screen User Interface. The 980
software package includes the firmware and gateware for all available modules.
2. Graphical User Interface for Windows PCs. This is the 980 Manager GUI that can be used to control all 980
instruments from a Windows PC.

11.18.2Test
Purity adjustment.
11.18.3Purpose
To produce correct colors in a displayed image, the electron beams from each of the three (3) guns in the CRT
should strike only their matching phosphors. A white image shows patches of various colors on a monitor with bad
purity. The purity adjustment(s) should be performed before doing any brightness or color tests. In some cases,
purity adjustments involve loosening and repositioning the yoke, in which case purity should be adjusted prior to
doing any geometry tests.
Method The methods used for adjusting purity on a color monitor depend on the type of monitor and CRT (for
example; Delta, In-Line or Single Gun). In most cases, the first step is to degauss the CRT.
Note: For a Delta Gun CRT, turn on only the red output. A solid uniform field of red should appear. If the color is not
uniform, adjust the yoke and the Purity Tabs assembly.
If purity cannot be corrected to acceptable limits, the monitor may not have been properly degaussed or there may
be a defect in the CRT or purity assembly.
11.18.4Test
Shadow mask warping.
11.18.5Purpose
Page 208
March 10, 2015
980 DP Video Generator - User Guide
Rev. A5
The purity characteristics of your CRT can change over time if you leave it on with a lot of video being displayed.
This may be due to the CRT’s electron beams striking its shadow mask with enough energy to cause the mask to
heat. This internal heating may be enough to cause the shadow mask to warp and give bad purity.
Method Set the purity image to white and allow the monitor to run for a few minutes. Any mask warping shows up
as a change in purity. You can use a color meter to measure the change. The BriteBox pattern may also be useful
for measuring shadow mask warping.

Rev. A5
Select the inverted version and perform the Brightness Control Adjustment test on the center box. Then, center the
light meter probe in each of the corner squares and note the reading you get for each square. The deviation
between each of the corner readings and the center reading should be within your specification limits.
11.22 Burst (TV formats only)
Description
The left side starts with reference white (+100 IRE) and black (+7.5 IRE) levels. This is followed by six bursts of sine
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, 2, 3, 3.58, and 4.43 MHz.
11.22.1Test
Frequency response.
11.22.2
Method
When viewed on a TV screen, the peak intensities of all of the bursts should match the white reference level. The
darkest portions between the peaks should match the black reference level.
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, is shown at the top of the next page. 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.
Some waveform analyzers can be set to detect and display the amplitude of the peaks. A typical amplitude
waveform for a good system is shown at the bottom of the next page.

The primary version of the Dot_24 image is shown below.
11.42.2Purpose
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.
Page 233
March 10, 2015
980 DP Video Generator - User Guide
Rev. A5
11.42.3Method
The convergence adjustments of most color monitors fall into two main categories. The first set of adjustments,
usually called Static Convergence, aligns the three beams in the center of the display. This method involves turning
on all three guns and adjusting the various magnets on the convergence assembly to produce all white dots in the
center of the display. The convergence assembly is located on the neck of the CRT. Different monitors and CRT
types may each require their own magnet-adjustment sequence.
After the center of the display is properly converged, the outer areas are adjusted by using the monitor’s Dynamic
Convergence controls. The number of controls, the area of the screen they affect, and their adjustment procedure
depends on the monitor under test.
11.42.4Test
Focus adjustments.
11.42.5Purpose
An out-of-focus monitor displays fuzzy pixels which, in turn, result in poorly formed and hard-to-read characters.
11.42.6Method
On monitors with a single (static) focus adjustment, adjust the control for the best average focus over the entire
screen. The focus at certain locations should be within specified limits.
Some monitors have a static and one or more dynamic focus controls. The sequence for adjusting them and the
areas of the screen they affect depend on the monitor under test.

11.85.1Description
The primary versions consist of a white, green (G and GRN), or magenta (M) crosshatch drawn on a black
background. The lines form square boxes. A single pixel dot is located in the center of each crosshatch box. The
number of boxes formed depends on the version of the image selected and the screen aspect ratio of the currently
loaded format. The number in the image’s name refers to the number of boxes that are formed along the minor axis
for most aspect ratios. The generator calculates the ratio and then finds the closest match from the table on the
next page. Version names indicate the drawing method, as follows:
•
Versions ending in “i” draw from the inside (center) out. Any partial boxes are placed around the perimeter
of the image.
•
Versions ending in “o” draw from the outside in. Any partial boxes are placed along the centerlines of the
image.
•
Versions ending in “s” are the “i” version plus a 1-pixel thick border.
The secondary versions invert the images to black lines and dots on a white background. Hatch_G, Hatch_M,
GRN_HTCH and Magenta do not have secondary versions.

11.85.2Test
Convergence adjustment (color monitors only).
11.85.3Purpose
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.
11.85.4Method
The convergence adjustments of most color monitors fall into two main categories. The first set of adjustments,
usually called Static Convergence, aligns the three beams in the center of the display. This method involves turning
on all three guns and adjusting the various magnets on the convergence assembly to produce all white dots in the
center of the display. The convergence assembly is located on the neck of the CRT. Different monitors and CRT
types may each require their own magnet adjustment sequence.
After the center of the display is properly converged, the outer areas are adjusted by using the monitor’s Dynamic
Convergence controls. The number of controls, the area of the screen they affect, and their adjustment procedure
depends on the monitor under test.

regulation. This is done by observing the vertical lines at the left and right edges of the image. They should be fairly

Linearty (Linearity)
11.101.1
Description
Rev. A5
This image has three parts. The first part consists of six (6) 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 smaller circle is drawn at half the
diameter and concentric with the larger circle. 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 at every other pixel location. Every fifth mark is slightly longer. The color of the pattern
can be changed with the individual video output controls.
11.101.2
Test
Linearity adjustment.
11.101.3
Purpose
To present 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 present across the
entire screen, in a large portion of the screen, or localized in a very small area.
11.101.4
Method
The circles in the image can be used to do a general adjustment of a monitor’s linearity controls. Adjust the
controls to form perfectly round circles. The crosshatch image can be used to measure linearity and to make finer
control adjustments. All the full boxes in the crosshatch should be identical in size. Measure them with a ruler or a

Description
Rev. A5
This image has several parts. The first part consists of a large circle in the center of the screen. Its diameter equals
the lesser of the video height or width of the display.
The second part is a 10x10 box crosshatch. The crosshatch is drawn in from the outside edges, with any extra
pixels in the boxes placed along the vertical and horizontal axis. The vertical centerline is two pixels thick if the
format has an even number of active pixels per line. The horizontal centerline is two pixels thick if the format has an
even number of active lines per frame. A smaller box is added at the center of the image. The box is one-half the
height and two-fifths the width of one of the crosshatch boxes. Current format data is shown in the lower left
quadrant of the image. It shows the number of active pixels (H) and lines (V) as well as the vertical and horizontal
scan rates.
The primary version (shown below) consists of a white pattern on a black background. The secondary version has a
black pattern on a white background.
The image also includes blocks of focus-checking characters at various locations. The blocks are positioned inside
the crosshatch boxes and are up to 3x3 characters in size. The size of the blocks is limited by the number of
characters that can fit in one box.

The primary version of the Outline0 image consists of a rectangular white border on a black background. The
border is one (1) pixel wide and defines the active video area. Two (2) diagonal lines join the opposite corners.
A-full size cross is centered in the image. The horizontal line of the cross is one (1) pixel thick for formats with an
odd number of active lines and two (2) pixels thick for formats with an even number of active lines. The vertical line
of the cross is one (1) pixel thick for formats with an odd number of active pixels per line and two (2) pixels thick for
formats with an even number of active pixels.
The secondary version of these images draw black lines on a white background.
In the Outline1 version, the two diagonal lines are removed and short marker lines are added to the border lines
near to where the cross lines meet the border lines. The markers appear at both sides of the cross lines. The
distance between the marker lines and the cross lines is the greater of either two (2) pixels or one (1) millimeter.
In the Outline2 version, the two diagonal lines are removed and short marker lines are added to the corners, and

11.117.2
Test
Yoke tilt correction.
11.117.3
Purpose
The horizontal axis of a displayed image should line up with the horizontal axis of your monitor. Any tilt is likely due
to the yoke being rotated on the neck of the CRT. A rotated yoke makes any displayed image appear rotated.
11.117.4
Method
Place your monitor on a flat surface so the face of the CRT is perpendicular to the surface.
Use a ruler or gauge to measure the height of each end of the image’s horizontal center line from the surface. The
difference between the two readings should be within specification for the monitor. If it is out of specification, the
yoke must be adjusted. Loosen the hardware that clamps the yoke to the neck of the CRT and rotate the yoke until
the line is horizontal. Tighten the yoke-clamp hardware.

980 DP Video Generator - User Guide
Rev. A5
11.117.5 Test
Yoke winding orthogonality check.
11.117.6 Purpose
The horizontal and vertical deflection coils on the yoke should have their axes cross at exactly 90 degrees.
Improper orientation of the windings causes displayed rectangles to look more like nonorthogonal parallelograms.
This type of defect is almost impossible to correct with adjustments. It is usually easier to replace the defective
yoke.
11.117.7 Method
First, perform the yoke tilt correction described above. The vertical center line of the image should be perpendicular
to the work surface. If the deviation is beyond specification, the monitor should be rejected and sent back for repair,
rather than trying to magnet a defective yoke.
11.117.8 Test
Display size correction.
11.117.9 Purpose
A too-large active video size adjustment on a monitor may cause information to be lost around the edges of the
screen. A too-small active video size adjustment may make some displayed information hard to read. The correct
size is needed to obtain the correct aspect ratio. You need the correct aspect ratio to get round circles and square
squares.
11.117.10
Method
First, determine the correct physical size of the active video area for the display. This information usually is given in
a display’s specification sheet or service manual. The size should match the sizes in the format you are using. The
size setting of the current format can be checked using the Format test image.
Place a ruler or gauge along the horizontal line of the image and adjust the monitor's horizontal size control until
the distance between the end points matches the specified value.
Move the ruler or gauge to the vertical line and adjust your monitor's vertical size control until the distance between
the end points matches the specified value.
11.117.11
Test
Parallelogram distortion check.
11.117.12
Purpose
Parallelogram distortion is very difficult to correct with magnets because the correction often causes barrel
distortion. Therefore, you should decide early whether your monitor meets this specification. The problem usually
can be traced to the improper winding of the yoke coils. If the problem is not too severe, it may be corrected by
adding or adjusting magnets on the yoke. However, if the distortion is excessive, it may be an indication of a
defective yoke which cannot be corrected with magnets.
Page 315
March 10, 2015
980 DP Video Generator - User Guide
11.117.13
Rev. A5
Method
Measure the lengths of the two (2) diagonal lines. Any difference is an indication of parallelogram distortion. The
difference in readings should be within the specifications of the monitor.
If the difference in the readings is too far beyond specification, the monitor should be rejected and sent back for
repair, rather than trying to magnet a defective yoke.
11.117.14
Test
Trapezoid distortion correction.
11.117.15
Purpose
This image gives you a way to measure trapezoid distortion in your monitor. If the distortion is not too severe, you
may be able to correct it by adding or adjusting magnets on the yoke.
11.117.16
Method
Perform the yoke winding orthogonality check and parallelogram distortion check first to avoid wasting time on a
monitor with a defective yoke.
Measure the width of the image at the top and bottom of the display. Any difference in readings should be within the
specification limits. Measure the height of the image at both sides of the display. Again, any difference in readings
should be within specification limits. If either of the differences is out of specification, the trapezoid distortion of the
monitor is out of specification.
Add or adjust magnets on the yoke to correct the problem. The pin and barrel distortion correction should be
repeated to make sure that it is still in specification.
11.117.17
Test
Pin and barrel distortion correction.
11.117.18
Purpose
If perfectly linear sweep signals are sent to a perfectly wound deflection yoke mounted on a perfect CRT, you would
not necessarily get a perfectly formed raster. Instead you would likely get a raster that had its corners stretched
away from the center, resembling a pin cushion. This distortion occurs because the geometry of the deflected
electron beam does not match the geometry of the tube face plate. Also, imperfections in the yoke or CRT may
affect this problem. In some cases one or more corners may be pulled towards the center of the raster causing it to
look like a barrel. Uncorrected raster distortion carries over as distortion of the displayed image.
11.117.19
Method
A slot gauge may be used to determine if the amount of pincushion or barrel distortion is within limits. A basic slot
gauge may consist of a piece of opaque film with at least two (2) transparent slots in it. One slot is used for top and
bottom distortion and the other is used for the sides. By positioning the correct slot over each portion of the border
line, the entire line should be visible. If this cannot be done at all four sides, the monitor requires correcting.
There are two main ways of correcting pincushion distortion. The first involves placing or adjusting magnets on the
yoke. This is a trial-and-error method. However, skilled operators develop a feel for how strong a magnet to use and
Page 316
March 10, 2015
980 DP Video Generator - User Guide
Rev. A5
how to place it in order to get the desired correction. If any correction is performed, the trapezoid distortion
correction should be repeated.
The other correction method involves adding correction signals to the deflection signal driving the yoke. This
method is usually found in color monitors, where adding magnets to the yoke would cause problems with
convergence and purity. The type and number ofadjustments depends on the monitor being tested.

11.134.1
Description
Rev. A5
In the primary version, 15 small white boxes move back and forth between diagonal guide lines. The lines form 15
side-by-side tracks. The size of each box is scaled to the light meter box size set by the MSIZ system parameter.
The image does the following:
•
The box in the center track (marked “1X”) moves one scan line vertically and one pixel horizontally for each
vertical frame of refresh.
•
The seven boxes to the right of the center track (marked “2X” through “8X”) move 2, 3,4, 5, 6, 7, and 8
pixels and lines per frame, respectively.
•
The seven boxes to the left of the center track (marked “/2” through “/8”) move one scan line vertically and
one pixel horizontally for every 2, 3, 4, 5, 6, 7, and 8 vertical frames of refresh, respectively. These boxes
are at the bottom of the tracks.
In cases where the next move would cause the box to move beyond the end of its track, it immediately reverses
and moves the correct distance in the opposite direction for the next frame.
A continuously-running counter appears in the upper left corner of the image. The number shown is the number of
vertical frame refreshes that have occurred since the generator was first powered up.
The secondary version draws a black image on a white background.
An example of the primary version of the Persist image is shown below:

Purpose
The phosphors on the face of most CRTs continue to glow for a short period of time after the electron beam has
stopped energizing them. This phenomenon is called persistence. A certain amount of persistence is desirable in
Page 333

most applications. It prevents a flickering of a displayed image that most users would find objectionable. On the
other hand, a CRT with an overly long persistence time causes moving objects to leave a blurred trail.
11.134.4
Method
A flickering in the slower moving boxes indicates that the combination of refresh rate and phosphor persistence is
not suitable for long-term viewing.
A fading tail left behind by the faster moving boxes indicates that the display may not be suitable for viewing
animated images.

11.143.1
Description
Rev. A5
This image is used to view a specific range of grayscale levels (ranges up to 1024) throughout the entire range
allowed by deep color support in the generator (i.e. 36 bit/pixel or 12-bit/component = 4096). If you set the ramp to
display the maximum color depth supported by the display under test you will see a nearly uniform ramp depending
on the horizontal resolution of the active format.
The following is a sample of the Ramp12 image is rendered on a display.

RampDif
11.144.1
Description
Rev. A5
This image has two ramps. One on the top and one on the bottom. It enables you to show a contrast of color
depths. For example you can specify that the top ramp use 12-bit/component deep color and the bottom ramp
10-bit color. You can then view the image and see whether banding occurs and how pronounced, in the either of
the ramps. If the display under test supports 12-bit/component color, the top ramp will show a near uniform ramp
on the top (depending on the horizontal resolution of the active format). The bottom ramp will show more
pronounced banding because the range of the ramp is greater than the color depth.
This image is used to view two specific range of grayscale or color levels (ranges up to 512) throughout the entire
range allowed by deep color support in the generator (i.e. 36 bit or 4096). You need to set the pixel depth in the
generator to 24 bit (PELD = 32) in order to access 512 grayscale or color levels on a single image rendered on a
display. The following is a sample of the RampDif image is rendered on a display.

SMPTE133
11.160.1
Description
Rev. A5
This image is based on a recommended practice (RP-133) test pattern designed by the Society of Motion Picture
and Television Engineers (SMPTE). The original application was used in testing and evaluating medical imaging
monochrome displays. The image now is used in many different display applications. The image is self-scaling as
to the number of active pixels and active lines used. Some of the image’s elements have minor differences from the
original SMPTE specification.
These differences are noted in descriptions of the individual elements.
The image is drawn on a reference background having a 50% intensity level. The background covers the
entire active video area.
Crosshatch – There are 10 boxes vertically. The number of horizontal boxes is based on the physical aspect ratio
determined by the HSIZ and VSIZparameters in the currently loaded format. The boxes are perfectly square with
any fractional spaces placed around the outside edges of the image. The vertical lines are two (2) pixels thick while
the horizontal lines are two (2) scan lines thick. Small crosses indicate the intersection of the horizontal and vertical
lines when they are covered by other parts of the image. All parts of the crosshatch are normally drawn using a
70% intensity level. A 75% level is used in the secondary version.
Resolution patch – The patch is made up of six (6) smaller boxes that are each about 6.25% of the height of the
display. The boxes are made of alternating intensity (0 and 100%) stripes. The stripes run vertically and
horizontally. The stripes may be one (1), two (2) or three (3) pixels wide each. Details of the patch are shown in the
lower half of the following illustration. The patches are located in each corner of the main image and in the center.
They are oriented with the highest resolution and contrast boxes closest to the outside corners. The 48%-53%,
48%-51% and 50%-51% level patches are omitted in the secondary version.
Grayscale boxes – Twelve (12) boxes at eleven (11) intensity levels are clustered around the center of the main
Page 361

980 DP Video Generator - User Guide
Rev. A5
image. They start at 0% and increase in 10% steps to100% with two (2) boxes at a 50% level. All of the
grayscale boxes are omitted in the secondary version.
Gamma check dither box – A small box is drawn inside the right-hand 50% grayscale box. The box is half the
width and height of the larger box. The box consists of a checkerboard of alternate one-on and one-off pixels. The
alternate pixels have levels of 0 and 100%. This smaller box is not part of the original SMPTE specification and is
omitted in the secondary version.
Contrast boxes – Two (2) boxes are drawn adjacent to the grayscale boxes. They are at 0 and 100% levels.
There are smaller boxes drawn inside each box at 5 and 95% levels. The contrast boxes are omitted in the
secondary version.
Black and white windows – Two (2) horizontal bars are located above and below the grayscale boxes. Their
height equals 8% of the display height. There are half-size bars centered in the larger bars. In the primary version,
the dark portion of the windows is at a 5% level and the bright portion is at a 95% level. Zero and 100% levels are
used in the secondary version.
Border – A border line is drawn around the image. It is set in from the edges of displayed video a distance
equal to 1% of the displayed height and has a thickness equal to 0.5% of the displayed height. The intensity
level is the same as that of the crosshatch lines.
Circle – A large circle is centered in the image. It touches the top and bottom of the active video area when the
aspect ratio is wider than it is high (landscape-type display). The circle touches the left and right sides of active
video when the aspect ratio is taller than it is wide (portrait-type display). The intensity level is the same as that of
the crosshatch lines. The circle is not part of the original SMPTE specification.
Resolution data - The number of active pixels per line and the number of active lines is shown as text below the
lower black and white window. The pixel depth also is shown. The intensity level of the text is the same as that of
the crosshatch lines. The displaying of the data is not part of the original SMPTE specification.
The secondary version adds a row of six (6) color bars above and below the black-and-white windows. The order of
the colors, from left to right, is red, green, blue, cyan (g+b), magenta (r+b) and yellow (r+g). The top row is drawn at
100% intensity levels and the bottom row is drawn at 50% intensity levels. Color bars are not part of the original
SMPTE specification.

Description
Rev. A5
This image is based on an engineering guideline (EG1-1990) test signal specified by the Society of Motion Picture
and Television Engineers (SMPTE). The SMPTE pattern, in turn, is derived from an EIA standard test pattern
(RS-189-A). The image, is set up to be generated by an 801GX generator as an encoded TV output. It is 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. The image is available on all models as a
component RGB signal. Some of the image’s elements have some differences from the original SMPTE
specification.
These differences are given in descriptions of the individual elements.
•
The 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. They are similar to the 801GX’s TVBar_75 image without the last black bar.
•
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.
•
The right side of the lower 25% of the image contains a narrow 12.5 IRE gray bar. Due to a hardware
limitation on the 801GX, this portion of the pattern does not match the original EIA and SMPTE patterns.
The original patterns had +3.5 (blacker than black) and +11.5 IRE bars separated by a +7.5 IRE (black)
bar.
•
The remaining central 8% of the image contains a row of chroma set bars. These bars are part of the
SMPTE pattern but are not in the EIA pattern. The order of the alternating color and black bars matches
those in the SMPTE pattern.

Rev. A5
Purpose
This general purpose pattern can be used to check the video handling capabilities of most parts of a television
system.
11.161.4
Method
When viewed on a TV screen, all of the upper color bars should be correct and in the order shown. The hue and
intensity of each bar should be uniform over the entire bar.
The image can be used with a TV waveform analyzer to check the performance of a video system. The upper color
bars, as they would appear on a waveform analyzer, are shown on a previous page.
11.161.5
Test
Color decoder performance.
11.161.6
Purpose
The image can used with a TV vectorscope to check for proper operation of a video color decoder. Vectorscope
signatures of the upper and lower portions of the image using NTSC encoding can be found on the previous page.
11.161.7
Method
The vectorscope signature for the color bars should hit the target test point for each color on the vectorscope’s
graticule. If you are using PAL encoded video, the signature will be similar to the one shown for the TVBar_75 test
image.
The three “legs” of the vectorscope signature for the -I and Q color difference signals should match the Burst, -I
and Q reference lines on the vectorscope’s graticule.
The following tests are based on the original SMPTE guideline:
11.161.8
Test
Visual chroma gain adjustment.
11.161.9
Method
To perform this test, you must have a way of turning off the red and green guns in the monitor under test. Turning
off the red and green video components of the 801GX generator’s video output will not work for this test.
This test uses the upper and central color bars. Switch off the red and green guns on the monitor. This will produce
four blue bars, separated by black bars. Adjust the chroma gain so that the brightness of each outer blue bar is
uniform over the entire bar. The gain is correct when the bottom 10% of each bar is the same brightness as the rest
of the bar.

lines of each image, as they would appear on a waveform analyzer, are shown on the following page.
The image is quite effective when used with a TV vectorscope to see how a video system handles an encoded
color signal.The image consists of a white crosshatch on a black background. The lines form square boxes when
the display’s active video area has a 4:3 aspect ratio. The vertical lines are made using sine-squared (2 T) pulses
(T = 125 nSec for NTSC and T = 100 nSec for PAL).

Test
Convergence adjustment.
11.176.6
Purpose
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 mis-converged monitor will appear as several
multi-colored lines, and the transitions between different colored areas will contain “fringes” of other colors.
11.176.7
Method
The convergence adjustments of most color monitors can be divided into two main categories. The first set of
adjustments, usually called “Static Convergence,” calls for aligning the three beams in the center of the display.
This method involves turning on all three guns and adjusting the various magnets on the convergence assembly to
produce all white lines and dots in the center of the display. The convergence assembly is located on the neck of
the CRT. Different monitors and CRT types may each require their own magnet adjustment sequence.
After the center of the display is properly converged, the outer areas can be adjusted by using the monitor’s
“Dynamic Convergence” controls. The number of controls, the area of the screen that they affect and their
adjustment procedure is dependent upon the monitor under test.

Rev. A5
Purpose
To present 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 will cause portions of an image to be stretched
while other portions will be compressed. Non-linearity in a monitor can show up in several ways. It may be present
across the entire screen, a large portion of the screen, or it may be localized in a very small area.
11.176.10
Method
Adjust the display’s linearity controls so that all of the boxes in the crosshatch are identical in size. You can
measure the boxes with a ruler or with a gauge made for the monitor under test. Any deviation should be within
your specification limits.

Description
Rev. A5
A zone plate is a radially symmetric pattern with low frequencies in the middle and high frequencies near the edge.
It is useful for experimenting with frequency- and direction-sensitive filtering and also for testing the anti-aliasing
capability of image resizing methods.
