About These Specifications

Specifications characterize the warranted performance of the instrument under the stated operating conditions.

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-2554 can be impaired if it is used in a manner not described in this document.

Input Characteristics

Note

All input characteristics are DC, AC_rms, or a combination unless otherwise specified.

Maximum switching voltage	30 V
Maximum switching current (per channel)	0.5 A
Maximum carry current (per channel)	0.5 A
Maximum RF power	10 W

Caution

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

Note

National Instruments 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.

Note

Switching active RF signals below 0 dBm may degrade signal integrity and decrease relay life. For more information about switching active RF signals visit ni.com/info and enter Info Code RFSwitching.

Typical DC path resistance
Initial	< 0.35 Ω
End-of-life	≥1.0 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.

RF Performance Characteristics

Characteristic impedance (Z₀)

75 Ω nominal

Insertion loss
≤1 GHz	<0.8 dB (<0.5 dB)
≤2 GHz	<1.3 dB (<0.9 dB)
≤2.5 GHz	<1.7 dB (<1.2 dB)

Voltage standing wave ratio (VSWR)
≤1 GHz	<1.25 dB (<1.1 dB)
≤2 GHz	<1.5 dB (<1.3 dB)
≤2.5 GHz	<1.75 dB (<1.5 dB)

Typical isolation
≤1 GHz	>47 dB
≤2 GHz	>40 dB
≤2.5 GHz	>40 dB
