  • Page 12: General Information

    General Information Adapter Set Overview The Keysight 11904S adapter set is designed to give network analyzer systems with 2.4 mm test ports (such as the Keysight 8510, 8722, and the PNA Series) the ability to perform measurements on devices with 2.92 mm connectors. The set can be used to achieve calibrated measurements of 2.92 mm devices up to 40 GHz, and 2.4 mm devices up to 50 GHz.

  • Page 19: Mechanical Characteristics

    Mechanical characteristics such as center conductor protrusion and pin depth are not performance specifications. They are, however, important supplemental characteristics related to electrical performance. Keysight Technologies verifies the mechanical characteristics of the devices in the kit with special gaging processes and electrical testing.
  • Page 20 When measuring pin depth, the measured value (resultant average of three or more measurements) is not the true value. Always compare the measured value with the observed pin depth limits in Table 2-2 to evaluate the condition of device connectors. Keysight 11904S User’s and Service Guide...

  • Page 27: Calibration Information

    Use, Maintenance, and Care of the Devices Calibration Information The calibration procedure for using the Keysight 11904S adapters requires that a 2.4 mm calibration be done using the calibration definitions of the 11904S instead of the calibration definitions of the Keysight 85056A 2.4 mm calibration kit. Although response, 1-Port, and 1-Path 2-Port calibrations may also be done, the following section is a general overview of a full 2-Port calibration, as it is the most complex of the calibrations.
