    This document lists specifications for the PXIe-2540. All specifications are subject to change without notice.

    PXIe-2540 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 PXIe-2540 can be impaired if it is used in a manner not described in this document.

    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 DC switching or carry power (per channel)

    10 W

    Maximum RF power (per channel, 50 Ω system)

    10 W

    Simultaneous channels at maximum RF power (up to 350 MHz)

    5
    spd-note-note
    Note  

    Maximum RF power derates as frequency and number of simultaneous channels increase and must not exceed the values shown in the following figures.

    Figure 1. Maximum RF Input Power
    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. Consult your RF source documentation for more information.

    DC path resistance

    Initial

    <2.1 Ω, typical

    End-of-life

    ≥3.1 Ω, typical

    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 3.1 Ω.

    VSWR

    ≤350 MHz

    <2.2 (<1.6, typical)

    Refer to the following figure for the VSWR of the PXIe-2540.

    Open CH isolation

    ≤350 MHz

    >75 dB, typical

    Refer to the following figure for the channel-to-channel isolation of the PXIe-2540.

    Figure 4. Open Channel Isolation, Typical
    Crosstalk

    ≤350 MHz

    <-35 dB, typical

    0.25 ms

    Maximum release time

    0.25 ms
    spd-note-note
    Note  

    Certain applications may require additional time for proper settling. Refer to the NI Switches Help at ni.com/manuals for information about including additional settling time.

    Relay life

    Mechanical

    1 × 109 cycles, typical

    Electrical (resistive, <10 pF load, DC or 50 Ω RF systems)

    10 V, 100 mA

    1 × 107 cycles, typical

    20 V, 500 mA

    5 × 106 cycles, typical

    spd-note-note
    Note  

    Reed relays are highly susceptible to damage caused by switching capacitive and inductive loads. Capacitive loads can cause high inrush currents while inductive loads can cause high flyback voltages. The addition of appropriate protection can greatly improve contact lifetime. For more information about adding protection circuitry to a capacitive load, visit ni.com/info and enter the Info Code relaylifetime. For information about inductive loads, enter the Info Code relayflyback.
