    General Information Incoming Inspection PSC Connectors PSC denotes a precision slotless connector. Precision slotless connectors are metrology grade connectors that have better electrical performance, better repeatability, and are more durable than slotted connectors. Clarifying the Terminology of a Connector Interface In this document and in the prompts of the PNA calibration wizard, the gender of cable connectors and adapters is referred to in terms of the center conductor.

    Use, Maintenance, and Care of the Cables Electrostatic Discharge Electrostatic Discharge Protection against ESD (electrostatic discharge) is essential while connecting, inspecting, or cleaning connectors attached to a static-sensitive circuit (such as those found in test sets). Static electricity can build up on your body and can easily damage sensitive internal circuit elements when discharged.
  • Page 20: Visual Inspection

    Use, Maintenance, and Care of the Cables Visual Inspection Visual Inspection Visual inspection and, if necessary, cleaning should be done every time a connection is made. Metal particles from the connector threads may fall onto the mating plane surface of the connector when it is disconnected.
  • Page 21: Precision Slotless Connectors (2.4 Mm)

    Use, Maintenance, and Care of the Cables Precision Slotless Connectors (2.4 mm) Precision Slotless Connectors (2.4 mm) The female 2.4 mm connectors in the cable sets are metrology-grade, precision slotless connectors (PSC). Precision slotless connectors are used to improve accuracy. A characteristic of metrology-grade connectors is directly traceability to national measurement standards through their well-defined mechanical dimensions.
  • Page 22: Cleaning Connectors

    Use, Maintenance, and Care of the Cables Cleaning Connectors Cleaning Connectors Clean connectors are essential for ensuring the integrity of RF and microwave coaxial connections. 1. Use Compressed Air or Nitrogen Always use protective eyewear when using compressed air or nitrogen. WARNING Use compressed air (or nitrogen) to loosen particles on the connector mating plane surfaces.
  • Page 23 Use, Maintenance, and Care of the Cables Cleaning Connectors 3. Clean the Mating Plane Surfaces a. Apply a small amount of isopropyl alcohol to a lint-free cleaning swab. b. Clean the center and outer conductor mating plane surfaces. Refer to Figure 2-1 on page 2-4.
  • Page 24: Gaging Connectors

    Use, Maintenance, and Care of the Cables Gaging Connectors Gaging Connectors The gages available from Keysight Technologies are intended for preventive maintenance and troubleshooting purposes only. (See Table 4-1 on page 4-4 for part number information.) They are effective in detecting excessive center conductor protrusion or recession, and conductor damage on test cables and other accessories, DUTs, and calibration kit devices.
  • Page 25: Gaging Procedures

    Use, Maintenance, and Care of the Cables Gaging Connectors Gaging Procedures Gaging 2.4 mm Connectors Always hold a connector gage by the gage barrel, below the dial indicator. This NOTE gives the best stability, and improves measurement accuracy. (Cradling the gage in your hand or holding it by the dial applies stress to the gage plunger mechanism through the dial indicator housing.) 1.

  • Page 27: Making Connections

    Use, Maintenance, and Care of the Cables Making Connections Making Connections Good connections require a skilled operator. The most common cause of measurement error is bad connections. The following procedures illustrate how to make good connections. How to Make a Connection Preliminary Connection 1.
  • Page 28 Use, Maintenance, and Care of the Cables Making Connections Using a torque wrench guarantees that the connection is not too tight, preventing possible connector damage. It also guarantees that all connections are equally tight each time. Prevent the rotation of anything other than the connector nut that you are tightening. It may be possible to do this by hand if one of the connectors is fixed (as on a test port).
  • Page 29: How To Separate A Connection

    Use, Maintenance, and Care of the Cables Handling and Storage 4. Tighten the connection just to the torque wrench break point. The wrench handle gives way at its internal pivot point. See Figure 3-4. Do not tighten the connection further. You don’t have to fully break the handle of the torque wrench to reach the CAUTION specified torque;...
  • Page 30: Avoiding Cable Movement

    Use, Maintenance, and Care of the Cables Handling and Storage Avoiding Cable Movement When you use cables to make a precise calibration, you may have to fixture the cables to prevent excessive movement after the calibration. In some cases, unless you restrict cable movement, you may not be able to perform a verification after the calibration, especially if you use a precision calibration kit.
