    PXI-2597 Specifications

    Specifications characterize the warranted performance of the instrument under the stated operating conditions. Data in this document are Specifications unless otherwise noted.

    Typical Specifications are specifications met by the majority of the instrument under the stated operating conditions and are tested at 23 °C ambient temperature. Typical specifications are not warranted.

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

    Caution  

    The protection provided by the PXI-2597 can be impaired if it is used in a manner not described in this document.

    Input Characteristics

    spd-note-caution
    Caution  

    Use precaution when using the PXI-2597 to avoid electrical shock.

    Maximum voltage

    90 Vrms, CAT I
    spd-note-caution
    Caution  

    This module is rated for Measurement Category I and intended to carry signal voltages no greater than 100 V. This module can withstand up to 500 V impulse voltage. Do not use this module for connection to signals or for measurements within Categories II, III, or IV. Do not connect to MAINs supply circuits (for example, wall outlets) of 115 or 230 VAC.[1]

    spd-note-caution
    Caution  

    When hazardous voltages (>42.4 Vpk/60 V DC) are present on any channel, safety low-voltage (≤42.4 Vpk/60 V DC) cannot be connected to any other channel.

    spd-note-note
    Note  

    NI recommends against switching active RF signals. As a relay actuates, the channel is momentarily unterminated. Some RF sources can be damaged by reflections if their outputs are not properly terminated. Refer to your RF source documentation for more information.

    spd-note-note
    Note  

    National Instruments recommends against switching RF signals below -35 dBm with this device.
