Quantum Data 780 Pattern Generator/Analyzer
Unit comes with all standard features plus the optional Cable Analyzer and Network Analyzer features.
This 780 with the newest, installed, software is capable, in conjunction with the CalMan software, not included, of calibrating the latest HDR displays. In addition the Quantum engineers created a set of custom buttons, see photo, to perform a quick check to verify the displays HDR capabilities.
The unit has been lightly used and comes with all the original included accessories and box.
The specifications follow:
• Pattern testing for HDTVs - Enables you to conduct pattern testing for an HDTV through the
HDMI and analog component outputs. Provides dozens of patterns with variation options on most.
• Custom bitmaps and pattern scrolling – The 780/780AH enables you to import bitmaps for use in
pattern testing. You can initiate a scroll of these bitmaps with user control over the rate and
extent of horizontal movement.
• Create custom formats using the standalone Format Editor.
• 3D bitmap pattern testing – The 780/780AH enables you to import 3D bitmaps for use in pattern testing. You can create your own bitmaps from any stereoscopic images you have using the Quantum Data Bitmap Conversion Tool available from the Quantum Data website:
http://www.quantumdata.com/apps/3D/BMP_conv.asp. There are some sample 3D bitmaps on this webpage
• Video confidence test of an HDMI source device – The 780/780AH enables you to view the
incoming video on the 780/780AH’s LCD screen. 780AH enables the incoming image to be routed out
the HDMI output connector if unused. 780AH also enables scrolling to view an entire unscaled 4K
image received on the HDMI input port.
• Audio confidence test of an HDMI source device – The 780AH enables you to listen to the incoming
LPCM audio through the 780AH’s headphone jack on the front edge or through an embedded speaker.
There will be no sound when compressed audio is received on the incoming HDMI stream.
• Audio Return Channel confidence test of an HDMI 1.4 A/V receiver – The 780AH can emulate an ARC
Tx device on its HDMI IN port. Note: The 780AH does not support enabling ARC on the AV receiver,
therefore you will have to enable ARC through some other means.
• Audio testing for AVRs and HDTVs – The 780/780AH provides multi-channel digital audio test
patterns through the HDMI, SPDIF and optical outputs. A variety of audio patterns and formats are
provided at sampling rates from 32kHz up to 192kHz and bit depths of 16, 20 and 24. Format
supported are Dolby Digital and DTS compressed formats and lossless compressed or high bit rate
• Installer Utility – Provides simplified diagnostics of HDMI interoperability problems in an HDMI
installation. The Installer utility enables installers to connect the 780/780AH into an HDMI
network and quickly conduct diagnostics without required detailed knowledge of HDMI protocols.
• Command line interface for automated testing.
1.4.2 Network Analyzer features
The following features are available with the Network Analyzer option:
• HDCP test of an HDMI sink or input to a repeater device – The 780/780AH enables you to run an
HDCP functional test on an HDMI sink device directly or through a repeater device.
• EDID test of an HDMI HDTV or input to a repeater device – The 780/780AH enables you to run an
EDID functional test on an HDMI sink device directly or through a repeater device. You can view the entire EDID in human readable text. You can also run a portion of EDID compliance test.
• Video test of an HDMI source device – The 780/780AH provides an HDMI input for testing HDMI
source devices. You can run a verification test of a video source which includes timing and format
information and an indication of whether the video is HDCP content protected.
• Data Island test of an HDMI source device – The 780/780AH provides an HDMI input for testing HDMI source devices. You can view the infoframes and other data islands.
• Audio test of an HDMI source device – The 780/780AH provides an HDMI input for testing HDMI
source devices. You can run a verification test of an audio source which includes decoding of the
audio IEC headers, audio infoframes and audio sample packet headers including parsing out of the
channel status bits.
• EDID test of an HDMI source device – The 780/780AH’s HDMI input can be provisioned with any EDID
you have access to. You can verify that a source device responds properly to the provisioned EDID.
The EDID could be a known-good EDID or an EDID that you have created specifically for testing.
• HDCP test of an HDMI source device – The 780/780AH enables you to run a test to determine how
many HDCP devices an HDMI source can support during HDCP authentication.
CEC ping test of any HDMI device – The 780/780AH enables you to run a CEC ping test on an HDMI
1.4.3 HDMI Cable and Repeater test features
The following features are available with the Cable and Repeater test option:
• HDMI Cable & Repeater test – Because the 780/780AH has both an HDMI input and an HDMI output, you can loop a cable or entire HDMI distribution networks comprised of splitters, extenders, repeaters, switches, etc. from the 780/780AH’s output to input and run a pseudo-random noise pattern test to determine pixel errors on the TMDS lines. The feature also runs a continuity test on the DDC test pair, CEC bus, the +5V line and the hot plug lead. The Repeater test also shows you the hot plug delay between the downstream side and the upstream side and the pulse width. The Cable & Repeater Test enable you to test a cable, repeater or distribution network if the source and sink ends are collocated. If the source and sink ends are not collocated then you need to use the Frame Compare test described below.
• HDMI Frame Compare test – Because the 780/780AH has an HDMI input, you can emulate a sink and
test a distribution network at the sink end. The feature works by capturing a frame of video from
the source and then comparing that frame, pixel-by-pixel, to subsequent frames. Errors are shown
along with the number of frames tested which 10 frames.
