Overview

The NI PXle-5842 Vector Signal Transceiver is a high-performance vector signal transceiver, which is used in applications such as radio frequency (RF) testing, measurement and prototyping. It combines functions such as RF signal generators, RF signal analyzers, and user-programmable FPgas, providing a flexible software-defined radio architecture.

Main performance indicators

Frequency range: Supports a specific RF frequency range, which can be used for signal generation and analysis in different frequency bands, meeting various application requirements.

Bandwidth: It has a relatively high instantaneous bandwidth, such as 1 GHz or wider, and is capable of handling complex wideband signals. It is suitable for tests such as Advanced Digital predistortion (DPD) and high-wideband signal tests such as radar, LTE-Advanced Pro and 5G.

Signal generation accuracy: It can generate high-precision RF signals, featuring low phase noise, high amplitude accuracy and excellent modulation quality, and can precisely simulate various communication signals and radar waveforms.

Signal analysis performance: It features high sensitivity and dynamic range signal analysis capabilities, capable of accurately measuring parameters such as amplitude, frequency, and phase of signals. It supports the detection of weak signals and demodulation analysis of complex signals.

Data transmission rate: Through the PCI Express Gen 3 bus interface, high-throughput data transmission is achieved, ensuring rapid data acquisition and signal processing, and supporting sub-nanosecond synchronization with other PXI modules.

Functional characteristics

Integrated design: In a single 2-slot PXI Express module, an RF signal generator, RF signal analyzer, high-performance user-programmable FPGA, and high-speed serial and parallel digital interfaces are integrated, reducing the volume and complexity of the system and facilitating integration and expansion.

Software-defined radio architecture: It supports software-defined functional configuration. Users can flexibly define parameters for signal generation and analysis, modulation methods, filtering characteristics, etc. through programming, adapting to different testing requirements and application scenarios.

Multi-input Multi-output (MIMO) capability: Supports MIMO configuration, enabling signal transmission and reception through multiple channels. It is suitable for testing and research in MIMO communication systems, enhancing the spectral efficiency and reliability of the system.

Real-time signal processing: By using user-programmable FPgas, real-time signal processing and algorithm implementation can be carried out, such as digital filtering, beamforming, signal demodulation and coding, etc., meeting the application requirements with high real-time performance demands.
