Emerson has introduced the NI PXIe-5633, a four-port vector network analyzer (VNA), alongside synchronized software updates for its NI PXIe-5860 vector signal transceiver. These new tools enable automated multiport S-parameter characterization and modulated RF testing within a single unified platform.
Why it matters
The system addresses increasing complexity in next-generation wireless architectures that rely on distributed, multi-antenna configurations. It allows engineers to consolidate disparate measurement workflows into one software-driven environment to improve efficiency from design validation to production.
The NI PXIe-5633 provides four ports for S-parameter measurements, doubling the port count of previous iterations. This hardware facilitates 4x4 MIMO (Multiple Input, Multiple Output) test setups, allowing synchronized characterization of complex antenna arrays.
The players
Emerson
A global technology and engineering firm that produces instrumentation and software for industrial and electronic test applications.
The details
The VNA, or vector network analyzer — an instrument used to measure the electrical performance of RF components by calculating how they transmit and reflect signal power — allows for the integration of multiple measurement types. By using a software-driven architecture, the system coordinates the NI PXIe-5633 and the NI PXIe-5860 VST, which handles the generation and analysis of modulated signals. This approach automates workflows by enabling users to perform S-parameter characterization alongside complex modulated RF measurements within a single test environment.

The Tech Race
The rollout mirrors the broader industry effort to simplify testing for high-order MIMO systems, which are essential for modern wireless standards. This move positions Emerson to support complex antenna arrays that are becoming standard in distributed wireless network architectures.
Engineers and labs focused on RF design validation can now integrate multiport testing into their existing PXI-based workflows. The system is designed to scale across the development lifecycle, from initial validation tasks to final production testing.
The takeaway
Emerson has shifted the standard for PXI-based network analysis to four ports, facilitating more complex MIMO testing in a unified architecture. Keep watch for upcoming integration benchmarks or comparative validation data involving the updated transceiver synchronization features.
