    The protection provided by the PXI-2536 can be impaired if it is used in a manner not described in this document.


    To ensure the specified EMC performance, operate this product only with shielded cables and accessories.


    Refer to the Read Me First: Safety and Electromagnetic Compatibility document for important safety and compliance information.


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

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

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

    Specifications are Warranted unless otherwise noted.


    Specifications are valid at 23 °C unless otherwise noted.

    All voltages are specified in DC, ACpk, or a combination unless otherwise specified.
