
Audio testing for AVRs and HDTVs
– The 780C provides multi-channel digital audio test patterns through
the HDMI, HDBaseT., 3G-SDI, 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 and HDBaseT interoperability problems in an
installation. The Installer utility enables installers to connect the 780C into an HDMI/HDBaseT network and
quickly conduct diagnostics without required detailed knowledge of protocols.

Command line interface for automated testing.
1.4.2 Network Analyzer features
The following Network Analyzer features are available:

HDCP test of an HDMI or HDBaseT sink or input to a repeater device
– The 780C enables you to run an
HDCP functional test on an HDMI or HDBaseT sink device directly or through a repeater device.

EDID test of an HDMI or HDBaseT HDTV, projector or input to a repeater device
– The 780C enables you
to run an EDID functional test on an HDMI or HDBaseT 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, HDBaseT or SDI source device
– The 780C provides an HDMI, HDBaseT or SDI
input for testing HDMI, HDBaseT or SDI 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 or HDBaseT source device
– The 780C provides an HDMI/HDBaseT input for
testing HDMI or HDBaseT source devices. You can view the infoframes and other data islands.

Audio test of an HDMI, HDBaseT or 3G-SDI source device
– The 780C provides HDMI, HDBaseT and 3G-
SDI inputs for testing 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 (for HDMI and
HDBaseT and parsing out of the channel status bits for 3G-SDI as well.

EDID test of HDMI or HDBaseT source device or outputs
– The 780C’s HDMI or HDBaseT input ports 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 or HDBaseT source device
– The 780C enables you to run a test to determine how
many HDCP devices an HDMI or HDBaseT source can support during HDCP authentication.

CEC ping test of any HDMI device
– The 780C enables you to run a CEC ping test on an HDMI device.
1.4.3 Cable and Repeater test features
The following features are available with the Cable and Repeater test option :

Cable & Repeater test
– Because the 780C has both digital video inputs and outputs, you can loop a cable
or entire distribution networks comprised of splitters, extenders, repeaters, switches, even hybrid networks
with HDMI, HDBaseT or 3G-SDI components, from the 780C
’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 HDMI or HDBaseT 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.
