Ensuring Signal Quality when Interconnecting the PXIe-5842

After you install the PXIe-5842 modules into your chassis, you must use the included cables to interconnect the PXI Express modules to each other and, if applicable, to any modules external to the PXI Express chassis. To ensure proper connections that maintain signal quality, adhere to these guidelines while interconnecting the modules.

  • Inspect all RF connectors before attaching mating cables. Clean with dry compressed air, if necessary, to remove any contaminants that may be present.
  • Position RF cables with instrument connectors to ensure center pins are straight and aligned before mating.
  • For all threaded RF connectors for your PXIe-5842 instrument, engage and finger-tighten the connector nuts. The connector nuts should thread easily without binding, but if not, ensure the connector is straight and that center pins have not been damaged.
  • Carefully tighten all threaded RF connectors to the torque specified in the interconnection process for your instrument using an appropriate torque wrench or torque screwdriver and driver bit; tighten only until the wrench or screwdriver reaches the torque limit.
    Notice Incorrect torque at threaded connections can damage connectors and degrade signal integrity.
To complete installation, continue with the relevant interconnection procedure for your PXIe-5842 instrument.
