6 Using the 780B Test Instrument to Test HDMI Source Devices
This section provides procedures for testing HDMI source devices such as DVD players, set top boxes and
outputs on repeater devices.
6.1 Testing Video from an HDMI Source Device
This subsection describes how to test the video on HDMI source devices.
6.1.1 Connection Configurations for Testing HDMI Source Devices
The 780B
’s HDMI input port acts as a “reference” HDMI sink device. Therefore it enables you to emulate a
known good HDMI sink device to conduct a basic confidence test of an HDMI source device. This test ensures
that you are receiving a valid HDMI video signal by displaying the timing of the incoming signal and informing
you whether it is HDCP encrypted or not. You can run this test in three configurations:

Source device connected directly to the 780B HDMI IN connector.

Source device connected to the 780B HDMI IN connector through a repeater device.

780B HDMI OUT and HDMI IN ports acting as both as a known good source and a known good sink
connect to both the input and output of the repeater device.
In all cases the 780B is emulating a sink to test an upstream source. In the third configuration, the 780B is
emulating both an HDMI source and sink. These test configurations are shown below.
