
Audio Return Channel confidence test of an HDMI 1.4 A/V receiver
– The 780B can emulate an ARC Tx
device on its HDMI IN port. Note: The 780B 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 780B 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 HDMI formats.

Installer Utility
– Provides simplified diagnostics of HDMI interoperability problems in an HDMI installation.
The Installer utility enables installers to connect the 780B into an HDMI network and quickly conduct
diagnostics without required detailed knowledge of HDMI protocols.

Command line interface for automated testing via RS-232 or USB.
1.4.2 Network Analyzer features
The following Network Analyzer features are available:

HDCP test of an HDMI sink or input to a repeater device
– The 780B 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 780B 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 780B 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 780B 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 780B 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 780B’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 780B 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 780B enables you to run a CEC ping test on an HDMI device.
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 780B 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 780B
’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.
1.4.4 Auto EDID Test
The following features are available with the Auto EDID test option :

Select a series of EDIDs to test a source’s handling of them.

Emulate the EDIDs on the 780B HDMI Rx port.
