    Note: The power switch in the front is used when you are turning off the 980/980B for a short period of time. For extended off periods, it is best to power down the 980 by first using the power button on the front and then the rocker switch on the back.

  • Page 7: Making The Physical Ethernet Connections

    If you are connecting through your corporate LAN, the PC hosting the Test Automation System will typically have an IP address assigned to it through DHCP services. You can either assign an IP address to the 980/980B directly or allow the network DHCP server to assign an IP address to the 980/980B. The procedures for changing the IP address of the 980/980B are provided in this subsection.

Connect an Ethernet cable from the 980/980B Ethernet jack on the back panel of the 980/980B to your corporate LAN or local Ethernet hub. The IP address on this 980B Ethernet port is configurable using the procedures that following.

    This subsection provides procedures on how to make the HDMI connection between an HDMI source device and the 980 HDMI Protocol Analyzer module. The images below identify the locations of the HDMI Rx interface on the 980 HDMI Protocol Analyzer module when installed in the 980 and 980B.

  • Page 13: Creating A Capabilities Declaration Form (Cdf)

    980 HDMI Protocol Analyzer compliance test function provides a set of forms that can be filled out and saved. This saved CDF is stored on the 980 test instrument and is used during the test. You must complete a CDF prior to running the test scripts through your ATS.

  • Page 14: Acquiring A Test Edid

    When running the source compliance test through an Automated Test System you will have to ensure that the EDID provisioned in the 980 HDMI Protocol Analyzer module’s Rx port supports all video and audio capabilities that your source device supports. Quantum Data provides the EDID(s) necessary. In most cases the Quantum Data default EDID will be sufficient for testing your source device.

  • Page 15: Executing The Source Compliance Test

    Your Automated Test System runs the HDMI source compliance test through a telnet session. Use the steps below to establish a telnet session to the 980. 1. Enter the telnet command at a terminal program to establish a telnet session request with the 980/9080B: telnet <IP Address>...

    That you have upgraded your 980 (if necessary) to a suitable released version. Note: The easiest way to verify that you have the proper license and that the 980 Protocol Analyzer is equipped with the proper released version is to run a simple quick test through the 980 GUI Manager. We recommend that you use the embedded 980 GUI Manager through the 980’s touch screen display.

  • Page 21 Performing the Capture (Raw TMDS) In the case of the 7-16,17,18,19 Protocol Tests, the 980 has to also look at the protocol data such as the preamble and guard band. This requires a separate capture of “raw tmds” data. The following series of commands set up the capture and trigger conditions, etc and then initiate the capture of the raw tmds data.
