4 Using the 780 to Run Video and Audio Pattern Tests on Sink
Devices
This chapter provides procedures for running audio and video pattern tests on high definition sink devices such as
HDTVs and projectors. The features and functions described in this chapter are provided with the standard 780; no
options are required. The following signal types are supported.
HDMI (via the HDMI physical connector)
DVI (via the HDMI physical connector)
YPbPr Component analog (via the HD VGA connector)
RGB Analog (via the HD VGA connector).
4.1 Making Physical Connections
The first step in testing a sink device is to make the physical connections between the 780 and the device(s) under test.
4.1.1 Connecting the 780 to the Display Device
Use the following procedures to make the physical connections from the 780 to the display device under test.
1. Make the cable connection between the appropriate the 780 video output connector (e.g. HDMI OUT or ANALOG)
connector and the input connector of the HDTV using the cables supplied.
2. Alternatively you may connect from the 780 video output connector to an HDTV through an HDMI repeater device
such as an A/V receiver. In this case make the HDMI connection between the HDMI OUT connector on the 780 and
the HDMI input of the HDMI repeater device using an HDMI-to-HDMI cable. Then connect the HDTV to an active
output on the repeater. The following illustrations depict the typical test configurations.

4.2.2 Procedures for Selecting an HDMI Resolution and Frame Rate
The procedures below describe how to select the resolution in HDMI.
Note: You can create your own custom formats using the Quantum Data Format Editor. These procedures are described
in the User Guide.
When you make a physical connection to an HDMI HDTV, a hot plug event will occur. There are two modes the 780 can
be set in when testing HDMI sink devices that determine how the 780 responds to this hot plug event: 1) Hot plug formats
On; 2) Hot plug formats Off.
When hot plug formats are On and a hot plug event occurs, the 780 will read the EDID of the display device connected to
its output port. It will then automatically configure the list available signal types (resolutions and frame rates) to only those
supported by the HDMI sink device. The 780 will also be configured to output the signal indicated in the EDID as the
―preferred‖ timing. The preferred timing is highlighted in green following a hot plug event.

780 Handheld Test Instrument Page 12

Revision A19
When hot plug formats are Off, the 780 will display all viable HDMI formats for the HDMI interface whether they are
supported by the display or not.
1. Select the Preferences from the 780 top level menu.
2. Select the Hot Plug Formats mode to On or Off as desired. Refer to the screen above.
3. Touch select the interface button (left button on the bottom panel). Refer to the figure below.
For the HDMI interface, you will set the Color Space, sampling mode, Bit Depth and Format Type.
4. Touch select the resolution and frame rate (middle button on the bottom panel). Refer to the figure below.

780 Handheld Test Instrument Page 13
Quick Start Guide
Revision A19
For the HDMI formats, there are color codes that are applied to the Resolution and Frame Rate selections. The following
is a summary of their meaning:
A Resolution or Frame Rate with white lettering but with no outline –a Resolution or Frame Rate that appears in
the EDID and has a short video descriptor associated with it.
A Frame Rate with green lettering and with white outline –The Frame Rate that is currently selected.
A Frame Rate with red lettering but with no outline –The Frame Rate is not supported by the EDID for that
Resolution.
A Frame Rate(s) with green lettering and with white outline –The Frame Rate along with the currently selected
Resolution that is the ―preferred‖ timing.
A Frame Rate with black lettering but with no outline –The Frame Rate is not supported by the standard for the
selected resolution.
Note: When you make a physical connection to an HDMI HDTV, a hot plug event will occur. If Hot Plug Formats is
enabled on the Preference menu, when the hot plug event occurs, the 780 will read the EDID of the display device
connected to its output port. The output is automatically set to the preferred timing which is highlighted in green
following a hot plug.
4.3 Rendering Test Patterns on an HDTV

7. Select the 3D bitmap image from the Test Pattern list.
Note: When selecting 3D bitmap images, you will have to make sure that the 3D bitmap you use matches your
selection of 3D formats and timing (resolution). In the example above, a 3D Frame Packing bitmap is selected for
1280 x 720. Therefore you have to make sure that you select that specific timing (i.e. 1280 x 720) and that specific
3D format structure (Frame Packing).
4.5 How to Scroll a Bitmap Pattern
This subsection describes how to scroll bitmaps on your 780
4.5.1 Guidelines for Scrolling Bitmaps
There are two ways you can animate (move) a bitmap image: 1) image shifting (scrolling); 2) panning. You can shift or
scroll a bitmap image that you have imported into the 780 by modifying the X and Y parameters or by dragging and
panning. When you use the X and Y parameters, you are limited to linear scrolling. With panning you can move the
image in non-linear motions.
You can only scroll bitmaps whose overall pixel resolution is smaller than the resolution of the active format and you can
only scroll them within the bounds of the resolution of the active format. You cannot scroll the standard test patterns in
the 780.
In order to scroll a bitmap the name of the bitmap has to be “zp.bmp.”But you can scroll any bitmap. You just have to
make sure that you have named it ―zp.bmp‖ (without the quotes). The zone plate bitmap is the only bitmap that comes
standard with the 780.
4.5.2 Procedures for Scrolling Bitmaps
Use the following procedure to scroll your bitmaps.
1. Touch select the desired bitmap image, e.g. Zone Plate image from the list of video patterns.
2. Double touch select on the Zone Plate bitmap to access its options.

780 Handheld Test Instrument Page 19
Quick Start Guide
Revision A19
The Zone Plate Options menu appears:
3. Specify the Horizontal Movement by touch selecting the appropriate setting Slow, Medium, Fast.
4. Specify the Vertical Movement by touch selecting the appropriate setting Slow, Medium, Fast.
The pattern will begin to move around the raster of the display in accordance with the horizontal and vertical
settings. To halt the motion, touch Stop for either or both of the Horizontal Movement and Vertical Movement.
4.6 How to Pan a Bitmap Image
This subsection describes how to pan bitmap test patterns on your 780
4.6.1 Guidelines for Panning Bitmaps
There are two ways you can animate a bitmap image: 1) image shifting (scrolling) 2) panning. Here are the rules and
capabilities:
You can pan bitmaps whose overall pixel resolution is greater than the resolution of the active format only to the
extent of the difference between the resolution of the bitmap and the resolution of the format you currently have
selected.
You can pan bitmaps whose resolution is lower than the active format but only within the range of the excess space
in the raster. You cannot pan the standard test patterns in the 780.
4.6.2 Procedures for Panning Bitmaps
Use the following procedure to pan your custom bitmaps.
1. Select by double touching, the desired bitmap image, e.g. Master 1920x1080 image from the list of video patterns
(shown below).
