    This document lists specifications for the PXI-2593. All specifications are subject to change without notice.

    PXI-2593 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.

    spd-note-caution
    Caution  

    The protection provided by the PXI-2593 can be impaired if it is used in a manner not described in this document.

    Input Characteristics

    Maximum switching voltage

    150 V, CAT I (channel-to-channel and channel-to-ground)

    spd-note-caution
    Caution  

    This module is rated for Measurement Category I. It is intended to carry signal voltages no greater than 100 Vrms, 150 V pk, or 150 VDC. This module can withstand up to 800 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 VAC or 230 VAC.

    spd-note-caution
    Caution  

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

    Maximum switching current (per channel)

    0.5 A

    Maximum carry current (per channel)

    1 A

    Simultaneous channels at maximum current

    Up to 2

    spd-note-caution
    Caution  

    The switching power is limited by the maximum switching current and the maximum voltage and must not exceed 10 W.

    Maximum switching power (per channel)

    10 W

    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.

    Minimum switch load

    10 μA, 10 mV

    Maximum RF carry power (per channel)

    10 W up to 500 MHz

    DC path resistance

    Initial

    <1.0 Ω

    End-of-life

    ≥2.0 Ω

    Path resistance is a combination of relay contact resistance and trace resistance. Contact resistance typically remains low for the life of a relay. At the end of relay life, the contact resistance rises rapidly above 1.0 Ω.

    <1.4

    200 MHz to 500 MHz

    <1.8

    Channel-to-channel skew within each 8-channel bank is less than 100 ps. Only channels from standard topologies are listed in Table 1.
