This document lists specifications for the PXI-2543 multiplexer module. All specifications are subject to change without notice. Visit ni.com/manuals for the most current 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, AC_pk, or a combination unless otherwise specified.

Caution

The protection provided by the PXI-2543 can be impaired if it is used in a manner not described in this document.

Caution

Device relays might change state momentarily during electrostatic discharge.

Topology

Refer to the NI Switches Help at ni.com/manuals for detailed topology information.

Topology

Dual 4 × 1 multiplexers

Input Characteristics

Minimum input frequency	10 MHz
Characteristic impedance (Z₀)	50 Ω nominal
Coupling	AC
Maximum safe DC input voltage	±8 V

Maximum Safe Continuous RF Power

Chassis power ON	+30 dBm
Chassis power OFF	+20 dBm

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.

RF Performance Characteristics

Insertion loss
≤2.4 GHz	<4.1dB (<3.4 dB, typical)
≤6 GHz	<5.8 dB (<5.1 dB, typical)
≤6.6 GHz	<7.0 dB (<6.1 dB, typical)

Insertion loss thermal coefficient

α = 2050 ppm/°C

Use the following equation to calculate the insertion loss at a given temperature:

I L_{T}^{} = I L {_{T}^{}}_{0}^{} (1 + α (T - T_{0}^{}))

where

IL is insertion loss in dB
T is the temperature at which the property is being measured in °C
T₀ is the reference temperature in °C
α represents the insertion loss temperature coefficient in ppm/°C

Voltage standing wave ratio (VSWR)
≤2.4 GHz	<1.7 (<1.5, typical)
≤6 GHz	<1.8 (<1.5, typical)
≤6.6 GHz	<2.4 (<1.6, typical)

CH-COM isolation
≤2.4 GHz	>70 dB (>84 dB, typical)
≤6 GHz	>61 dB (>74 dB, typical)
≤6.6 GHz	>59 dB (<72 dB, typical)

CH-CH isolation
≤2.4 GHz	>69 dB (>90 dB, typical)
≤6 GHz	>58 dB (>74 dB, typical)
≤6.6 GHz	>53 dB (<71 dB, typical)

Bank-to-bank crosstalk

<-90 dB, typical

Channel-to-channel skew

<10 ps, typical

Propagation delay

1,720 psi, typical

Input 1 dB Compression

>27.6 dBm, minimum

>32.0 dBm, typical

Refer to the following figures for typical insertion loss, typical VSWR, and typical isolation, respectively.

Figure 1. Insertion Loss, Typical

Figure 2. VSWR, Typical

Figure 3. Isolation, Typical

Linearity

Second-order harmonic distortion (Input IP2 (IIP2))
IP2 (input)	>+89 dBm, typical

Note

Measurements are performed with single CW tones, ranging from -26 dBm to +10 dBm at the RF input. This specification is based on both experimental and calculated data.

Third-order intermodulation distortion (Input IP3 (IIP3))
IP3 (input)	>+54 dBm, typical

Note

Measurements performed with two 10 dBm input tones = 1 MHz apart. This specification is based on both experimental and calculated data.

Dynamic Characteristics

Maximum switch operate time

76 μs

Note

Switch operate time is defined as the time from TRIG IN falling to 10% to when the output reaches 90% of final value.

Note

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

Trigger Characteristics

Note

The PXI-2543 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.
