3 General Operation
This section describes power up, power usage and general operation.
3.1 Power Considerations
The 780/780AH has a rocker style power switch on the back panel. Refer to the photo below.
The 780/780AH is a portable battery powered test instrument. It is equipped with nickel metal hydride batteries.
It requires an overnight charge. Quantum Data recommends that you set the screen brightness to the minimum
level required. Turn the unit off if you are not going to be using it for extended periods.
The 780/780AH is supplied with the Part No 25-00094 12V DC power supply and charger as well as a part
number 30A00400A03 line cord. We recommend that you use the 780/780AH with the charger and only
use the batteries when fully charged for a short period of time—an hour or two—when power is not
available.
Important Notes about power usage and status:
Monitor the battery meter on the lower right.
The screen will automatically dim after 2 minutes of inactivity to save on battery life.
The 780/780AH will begin to chirp when it requires recharge. Turn the unit off or plug it in to the wall
charger when you hear the chirp.
A green indication or partial green indication shows the battery is being charged.
A gold color indicates that the device is being powered through the wall charger.
Fully charge the 780/780AH overnight.
You must touch an active portion of the LCD to update the battery indicator to show its power status.
Do not continue using the 780/780AH from battery power when the battery meter indicates that the
batteries are exhausted. When you see a thin green line at the right most portion of the battery icon,
turn the power off and switch to line power using the AC Charger adapter; then reapply power.

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 Creating and Using Custom Formats, EDIDs and Bitmaps.
When you make a physical connection to an HDMI HDTV, a hot plug event will occur. There are two modes the
780/780AH can be set in when testing HDMI sink devices that determine how the 780/780AH 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 780/780AH 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 780/780AH 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.
When hot plug formats are Off, the 780/780AH 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 780/780AH top level menu. Navigate to the second page by touch
selecting the More… key.

780/780AH Handheld Test Instrument – User Guide Page 23
November 17, 2016
Revision C2
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 780/780AH 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.
4.2.3 Procedures for Enabling AVMute
The procedures below describe how to enable AVMute. AVMute is an optional feature in HDMI that enables a
source to signal a sink to extinguish its audio and video. The source, in this case the 780/780AH emulating a
source sets the AVMute Set flag in the general control packet. The purpose of AVMute is to avoid audio
artifacts when switching resolutions.
1. Select the Preferences from the 780/780AH top level menu. Navigate to the second page by touch
selecting the More… key.

2. Assess the color gradation on each bar.
3. Close right eye to view image from left eye.
4. Subjectively compare the images to assess color
uniformity.
Method – Crosstalk (extinction ratio):
1. Close left eye to view image from right eye.
2. Verify that the bottom bar is extinguished. The extent to
which the bar is not extinguished represents the amount
of crosstalk.
3. Repeat for a test of the left eye
3D Cross Talk
Application: This is a 3D
pattern used to measure the
crosstalk (extinction ratio) for
frame packing, top and bottom

structures.
No variants
Description: This image is divided in two sections with four rows of
16 white boxes each. The top section is for testing with the left eye
open. The bottom section is for testing with the right eye open.
The background area surrounding the boxes is a series of
grayscale ramps. The ramps begin at 100 IRE and transitions to
50 IRE at the left end of the fourth row of each series.
Method – Calculating percent crosstalk:
1. Close right eye to test the left eye using the top section.
2. Check the visibility of the boxes. Any deviation from
black indicates crosstalk.
3. Assess where the box and its background blend such
that they are not distinguishable.
4. Calculate the degree of crosstalk as a percent by
counting the number of boxes (from the beginning of the
series to the box identified in step 3) and divide that by
127. Example if the 20th box blends with its background,
the crosstalk would be 20/127 * 100 = 15.7%
5. Repeat with the left eye closed to test the right eye.
