The global rollout of 5G networks and early-stage 6G research is fundamentally transforming telecommunications testing requirements. The technological complexity inherent in these next-generation networks demands sophisticated RF and microwave testing solutions that modular platforms uniquely provide.
Keysight Technologies demonstrated next-generation spectrum innovations in June 2024 to accelerate 5G and 6G advancements, including wideband active load-pull testing using PXI-based vector sources paired with network analyzers for RF performance validation. The broader Test and Measurement Equipment Market is experiencing parallel growth as telecommunications operators and equipment vendors increasingly rely on modular instruments for network deployment and optimization.
The shift towards electrification and autonomous driving in the automotive industry is increasing the demand for modular testing solutions. Testing Advanced Driver Assistance Systems (ADAS) requires validating sensor fusion across radars, lidars, cameras, and ultrasonic sensors. Starting July 2024, the European Union will require features such as automatic emergency braking, lane-keeping assistance, and intelligent speed assistance, with driver attention monitoring mandated in 2026. PXI-based test platforms, paired with software such as LabVIEW, provide the performance needed to validate automotive radar systems in the 77-81 GHz range under realistic conditions.
Pickering Interfaces has released PXI and PXIe fault insertion modules using MEMS switching technology for testing automotive Ethernet standards, including MultiGBASE-T1 protocols. In the U.S., the National Highway Traffic Safety Administration (NHTSA) will require automatic emergency braking with pedestrian detection by September 2029. These regulations are prompting manufacturers to invest in modular testing platforms to validate complex electronic control units and perform calibration checks across diverse scenarios.
The significant upfront costs associated with modular instrument systems create a major barrier for small and medium-sized enterprises. A complete PXI Express test system—including the chassis, controller, and specialized measurement modules—can require investments exceeding several hundred thousand dollars, especially for applications that demand high-frequency capabilities or multichannel configurations.
While modular platforms can offer long-term cost-effectiveness through scalability and reduced obsolescence, the initial purchase cost remains prohibitive for organizations with limited capital budgets. Moreover, the complexity of system integration and the requirement for specialized technical expertise to configure and maintain these platforms further increase the total cost of ownership. This can make it challenging for cost-sensitive market segments to adopt such systems.
Integrating modular instruments into existing test infrastructure poses significant technical challenges, despite the standardization efforts by the PXI Systems Alliance and IEEE. Organizations using legacy VXI systems may face compatibility issues when upgrading to PXI Express or AXIe platforms. The demand for skilled personnel proficient in software development, such as LabVIEW, creates workforce challenges, especially in regions with limited technical talent.
The need for specialized expertise in software programming and system architecture contributes to barriers in market adoption, particularly in developing economies. Ongoing maintenance, calibration, and software updates necessary for performance and regulatory compliance also incur continuous operational costs that may deter investment by cost-sensitive organizations.
The defense and aerospace sector offers significant growth opportunities for modular instrument manufacturers as governments increase investments in modernization. PXI- and VXI-based systems are vital for testing mission-critical applications like radar validation, avionics verification, and satellite communications.
Keysight Technologies noted that defense contractors use Automated Test Equipment (ATE) power supplies to validate transmit/receive modules for advanced radar systems, which require precise power sequencing. The ability to reconfigure test setups for various mission profiles without complete overhauls makes modular instruments attractive for long-term defense programs lasting several decades.
