  • Page 9 Based on measurements conducted by Wilder Technologies, the Cooling Module is an optional recommendation for use on the SFP-DD MCB (Receptacle) when testing modules of Power Class 6 or greater (not yet defined by specification). At these power classes, the case temperatures and heatsink temperatures of the SFP-DD MCB may exceed recommended limits (Per MSA and ASTM standards).

  • Page 10: Product Inspection

    SFP-DD Test Adapter User Manual Product Inspection Upon receiving the SFP-DD test adapters from Wilder Technologies, perform the following product inspection: • Inspect the outer shipping container, foam-lined instrument case, and product for damage. Retain the outer cardboard shipping container until the contents of the shipment have been inspected for completeness and the product has been checked mechanically and electrically.

    If the SFP-DD TPA must be turned or twisted to make connection to the DUT, avoid using the SFP-DD TPA housing alone to make this occur. Try to distribute the torque forces along the length of the test setup and cabling.
  • Page 12 2. Insert the mating High-Speed connector barrel and hand-tighten the free-spinning nut onto the connector while avoiding pulling, bending, or twisting the SFP-DD TPA coaxial cable. The SFP-DD TPA High-Speed connectors have flats that accept an open-end 1/4-inch or 5/16-inch wrench, depending on configuration.

    Observing simple precautions can ensure accurate and reliable measurements. Handling and Storage Before each use of the SFP-DD TPA, ensure that all connectors are clean. Handle all cables carefully and store the SFP-DD TPA in the foam-lined instrument case when not in use, if possible.

  • Page 14: Electrostatic Discharge Information

    Electrostatic Discharge Information Protection against electrostatic discharge (ESD) is essential while connecting, inspecting, or cleaning the SFP-DD 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: •...

  • Page 15: User Model

    An RX signal, inputted from a connected Signal Generator, is transferred through the HCB’s RX lines into the SFP-DD host under test. The Host responds by outputting TX signals which are transferred through the HCB, out through its TX lines into a connected Oscilloscope for measurement.

  • Page 19: Calibration Through De-Embedding

    Calibration Through De-Embedding The SFP-DD Test Adapters are fully passive components. Therefore, calibration compensating for the losses must occur within the test instrumentation that drives the SFP-DD Receivers or looks at the response of the SFP-DD Transmitters. The SFP-DD TPA’s have Touchstone S4P files for de-embedding the electrical length and losses within the TPA up to the SFP-DD connector interface pads.
