The National Instruments PXI-5671 Vector Signal Generator is a comprehensive solution designed for advanced signal generation applications within the PXI platform. It combines the capabilities of the PXI-5441 Waveform Generator and the PXI-5610 RF Signal Upconverter, providing a versatile system for generating and manipulating RF signals. Utilizing the NI-RFSG instrument controller and accompanied by the Modulation Toolkit for LabVIEW, the PXI-5671 streamlines control over waveform functions, allowing users to manage time and synchronization settings, continuous wave (CW) tones, and arbitrary waveform generation with ease.

This seamless integration supports various programming environments, including NI LabVIEW, LabWindows/CVI, and C, providing flexibility for developers and engineers. The Modulation Toolkit enhances functionality with tools for signal generation, analysis, and visualization of both custom and standard modulation techniques. Users can generate and evaluate custom modulation formats while accessing core measurement capabilities such as Error Vector Magnitude (EVM), Modulation Error Ratio (MER), and more. Furthermore, the toolkit offers features for simulating various impairments, including IQ Gain Imbalance, Quadrature Skew, and additive white Gaussian noise (AWGN), alongside comprehensive visualization options like trellis diagrams, constellation plots, and 2D/3D eye diagrams.

The PXI-5671 offers various onboard memory options, including 32 MB (part number 779079-02), 256 MB (part number 779079-03), and 512 MB (part number 779079-04), providing robust support for complex signal playback. With a maximum memory capacity of 256 MB, users can create and output extended and intricate waveforms, facilitating simulations that mimic real-world signal transmission scenarios with durations of up to 1.28 seconds. The physical dimensions of the PXI-5610 are 8.5 x 1.6 x 5.1 inches and the PXI-5441 measures 8.5 x 0.8 x 5.1 inches, with a combined weight of 53.2 ounces. Each unit is offered with a warranty spanning 2 to 3 years, and user and maintenance manuals are available for download. For pricing information, please contact a sales representative.
