Definitions

Warranted Specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

  • Typical—describes the performance met by a majority of models.
  • Nominal—describes an attribute that is based on design, conformance testing, or supplemental testing.

    • Values are Typical unless otherwise noted.

    Conditions

    Specifications are valid under the following conditions unless otherwise noted.

    • 0 °C to 55 °C

    PXIe-8520 Pinout

    The I/O of the interface devices installed within the PXIe-8520 interface carrier determine the available I/O.

    IVN-8532 Pinout

    Use the pinout to connect to the H-MTD Z (f) ports on the IVN-8532 when it is installed within the PXIe-8520.

    Each IVN-8532 has two H-MTD Z (f) ports.

    Environmental Guidelines

    Notice Failure to follow the mounting instructions in the product documentation can cause temperature derating.
    Notice This product is intended for use in indoor applications only.
    Notice All cabling should be strain-relieved near input connectors. Take care not to directionally bias cable connectors within input connectors when applying strain relief.
    Notice Cover all empty slots using filler panels.
