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

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, AC_pk, 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.

Topology

8 × 9 matrix

Input Characteristics

Maximum switching voltage	60 V DC (42.4 V_pk)
Maximum switching or carry current (per channel)	0.5 A

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

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

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.

RF Performance Characteristics

Characteristic impedance (Z₀)

50 Ω, nominal

Insertion loss
≤350 MHz	<3 dB (<2.3 dB, typical)

Refer to the following figure for the insertion loss of the PXIe-2540.

Figure 2. Insertion Loss, Typical

VSWR
≤350 MHz	<2.2 (<1.6, typical)

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

Figure 3. VSWR, Typical

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

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

Figure 5. Crosstalk, Typical

Propagation delay	<6 ns, typical
CH-CH skew	<2 ns, typical

Dynamic Characteristics

Simultaneous drive limit	40 relays
Maximum operate time	0.25 ms
Maximum release time	0.25 ms

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

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.

Trigger Characteristics

Input trigger
Sources	PXI trigger lines <0...7>
Minimum pulse width	150 ns

Note

The PXIe-2540 can recognize trigger pulse widths less than 150 ns by disabling digital filtering. For information about disabling digital filtering, refer to the NI Switches Help at ni.com/manuals.

Output trigger
Destinations	PXI trigger lines <0...7>
Pulse width	Programmable (1 μs to 62 μs)
