    Supported products The information in this manual covers the Tektronix products described below. ECO422D SD/HD The ECO422D is a highly versatile sync changeover unit designed for use in a serial SD/HD digital television environment. The ECO422D will accommodate Changeover Unit component or composite serial digital video signals, AES/EBU digital audio, tri-level sync, and analog black-burst signals.
  • Page 16 However, in the unlikely event both sync sources are faulty, the ECO422D will not alternate between the two sources. If necessary, this function may be overridden with the manual sync source selection.

    This does not apply to the three Option ELSW channels, which are buffered. To avoid this problem, work on an output only when the ECO422D is not in operation. Disconnect the output cable from the ECO422D before working on the cable, and verify proper termination before reconnecting the cable to the ECO422D.

  • Page 43: Figure 11: Eco422D User Configuration Switches (Default Position)

    CAUTION. Make sure that any channel that is not in use has checking disabled. If checking is not disabled, errors will always be generated and the ECO422D will not operate properly. No error checking also allows the maximum voltage, current, and frequency to pass through the ECO422D.
