    SMA Connectors SMA Connectors Good connections are essential for accurate calibrations and measurements and require a skilled operator. The most common cause of measurement error is poor connections. The following information is for use when connecting the two Waveform Generator cables to the DPT Test Fixture and when connecting the BNC-SMA cable to the PD1000-60002 Protection Probe.

    Use a Keysight 8710-1582, 0.56N-m (5 lb-in) 5/16 inch break-over torque wrench to make a final connection. A Torque wrench is supplied as part of the PD1500A Accessory Kit. Figure 7 Keysight 8710-1582 SMA Torque Wrench The Keysight 8710-1582, 5 lb-in Torque Wrench is a precision instrument and should be treated and maintained like a measuring instrument.

    SMA Connectors 3 Hold the torque wrench lightly, at the end of the handle only (beyond the groove). See the following figure. Torquing Direction Stop when handle begins to yield Figure 9 Using the Torque Wrench 4 Apply force downward to the wrench handle. This applies torque to the connection through the wrench.

  • Page 106: Inspect And Clean Connectors

    SMA Connectors Inspect and Clean Connectors Clean connector interfaces prolong connector life and produce more accurate and repeatable measurements. When using SMA female connectors, pay special attention to the contact fingers on the female center conductor. These can be bent or broken, and damage to them is not always easy to see. A connector with damaged contact fingers will not make good electrical contact and must be repaired or replaced.
