Technical Sharing | An Analysis of the Core Technologies and Typical Application Scenarios of Vector Signal Transceivers
2026-07-21
As technologies such as 5G, Wi‑Fi 7, and vehicle‑to‑everything (V2X) accelerate their deployment, the testing requirements for RF chips and wireless communication equipment are becoming more complex and urgent than ever. While traditional benchtop instruments offer robust functionality, they face significant limitations in system integration, test efficiency, and production‑line scalability. Consequently, how to achieve high‑precision, high‑bandwidth, and highly integrated RF signal testing within constrained spatial constraints has become a key focus for both R&D and manufacturing.
As a cutting-edge test instrument within the software-defined radio architecture, the vector signal transceiver is redefining the limits of RF‑test efficiency.
What is a vector signal transceiver?
Vector Signal Transceiver Integrates vector signal transmission and reception functions into a single unit. , leveraging a software-defined radio architecture to integrate RF and baseband vector signal analyzers with signal generators within a 2-slot PXI chassis. While boasting an exceptionally high level of hardware integration, the software platform supports a wide range of digital modulation and demodulation functions, including 5G NR, 4G LTE, Wi‑Fi, and Bluetooth. , providing the performance required to swiftly and efficiently address RF chip testing and wireless communication testing challenges—both today and in the future.
The vector signal transceiver consists primarily of two components:
Vector Signal Generator : The core functions are consistent with those of traditional benchtop instruments, supporting basic capabilities such as continuous-wave output, broadband signal generation, and modulation. Leveraging a wideband superheterodyne architecture, it eliminates LO leakage and image signals while also enabling IQ‑data modulation to generate broadband waveforms, thereby achieving real-time signal generation.
Vector Signal Analyzer Its functionality is identical to that of conventional benchtop instruments. The vector signal analyzer not only retains the swept‑frequency measurement capabilities of a traditional spectrum analyzer but also supports real‑time analysis and processing of wideband signals. Moreover, when deployed on a PXIe platform, it offers high‑speed data streaming and recording, significantly enhancing its capacity for long‑duration data acquisition and analysis.
