  • Page 7: The Embedded Displayport Test Adapter Care And Handling Precautions

    While individual high-speed coaxial cables within the test adapter have some rotational freedom, twisting the EDP-TPA as a unit, with one end held stationary, in excess of +/- 90° may damage or severely degrade performance. Adherence to Caution 5 (below) helps to avoid exceeding twist limits.
  • Page 8 The EDP-TPA female SMA connectors have flats that accept an open-end 1/4-inch or 6.5mm wrench. (Male SMA connectors have flats that accept an open-end 5/16- inch or 8mm wrench.) When attaching instrument cables to the EDP-TPA, it is recommended that the EDP-TPA connectors be mechanically held and the instrument cable SMA connectors be tightened to the equipment manufacturer’s...

  • Page 9: General Test Adapter, Cable, And Connector

    Before each use of the EDP-TPA, ensure that all connectors are clean. Handle all cables carefully and store the EDP-TPA in the foam-lined instrument case when not in use, if possible. Do not set connectors contact end down. Install the SMA protective end caps when the EDP- TPA is not in use.

  • Page 10: Electrostatic Discharge Information

    Electrostatic Discharge Information Protection against electrostatic discharge (ESD) is essential while connecting, inspecting, or cleaning the EDP-TPA test adapter and connectors attached to a static-sensitive circuit (such as those found in test sets). Electrostatic discharge can damage or destroy electronic components. Be sure to perform all work on electronic assemblies at a static-safe workstation, using two types of ESD protection: ...
