Description

PXI-5670: Product Overview
The National Instruments PXI-5670 is a high-performance RF vector signal generator designed for PXI-based test systems requiring sophisticated signal generation capabilities. This module functions as a programmable RF source capable of producing complex modulated signals for testing wireless communication systems, radar systems, and other RF components. The device covers a frequency range from 250 kHz to 2.7 GHz with an instantaneous bandwidth of 100 MHz, supporting a wide variety of communication standards and custom waveform requirements.
Installed in a PXI chassis, the module operates as a complete signal generation solution, incorporating a vector signal generator, RF local oscillator, and upconversion stages. The architecture supports both standard communication waveforms (such as WLAN, WiMAX, and LTE) and user-defined arbitrary waveforms. The module is designed for integration into automated test systems for research and development, production test, and system validation applications where signal fidelity and flexibility are critical requirements.

Core Features & Customer Value
The primary value of the PXI-5670 lies in its combination of wide bandwidth and high signal quality. The 100 MHz instantaneous bandwidth enables generation of complex wideband signals for testing modern communication systems, radar systems, and electronic warfare applications. The 16-bit resolution provides excellent dynamic range and signal fidelity, ensuring that generated signals accurately represent real-world conditions without introducing unnecessary artifacts or distortion.
The module’s software-defined architecture​ allows for flexible signal generation across multiple standards and custom waveforms. This programmability enables test engineers to adapt the instrument to evolving requirements without hardware changes, reducing system lifecycle costs. The comprehensive modulation capabilities​ support both standard communication protocols and specialized modulation schemes, making the module suitable for both commercial wireless testing and specialized defense applications.
Integration with the PXI platform​ provides synchronization capabilities with other instruments in the chassis, enabling multi-instrument test systems for complex RF characterization. The module can be synchronized with signal analyzers, digitizers, and other instruments to create complete transmitter test systems or hardware-in-the-loop simulation environments.
Typical Applications
In wireless communication testing, the module generates standard-compliant signals for receiver testing of devices implementing WLAN, WiMAX, LTE, and other communication standards, including multi-carrier and MIMO signals.
In radar system testing, the instrument creates pulsed RF signals with precise timing and modulation characteristics for evaluating radar receiver performance and signal processing algorithms.
For satellite communication systems, the module generates modulated carriers with specific phase noise characteristics and modulation formats for testing transponders and ground station equipment.
