Universal Wireless Tester
TEST MULTIPLE RF CHANNELS AND STANDARDS IN PARALLEL
Universal Wireless Tester
Unique non-signaling RF test platform for validation and production
Wireless communication standards are increasingly integrated into vehicles as well as smart home and Internet-of-Things applications. They form the basis for connected services, advanced HMIs, and autonomous driving. The combination of constantly evolving standards and the integration of multiple wireless technologies with many RF channels into new product designs means that measurement speed and quality are becoming a priority.
These developments require complex and parallel test solutions with high channel counts to meet throughput and yield targets.
NOFFZ and NI have jointly developed the Universal Wireless Tester (UWT) to address these test challenges. The UWT provides a suitable solution to meet the high RF channel count requirements while remaining very flexible and cost-effective.
Designed to be the most flexible platform for RF testing of modern wireless standards
The Universal Wireless Tester provides non-signaling verification of modern wireless and connectivity standards, e.g. C-V2X, 5G, 802.11 ax, BLE, and UWB.
The UWT reduces the testing duration through parallel testing of multiple DUTs, automatic RF port routing, and automatic resource utilization. For higher throughput, the system can be easily upgraded to up to four transceivers with an additional analyzer and generator. At the same time, downtime for maintenance or calibration is minimized through automatic reassignment between test adapters and transceivers.
This unique technology leads to a reduction in overall test costs by reducing test times. It also enables future-proof system scalability for 6 GHz Wi-Fi, 10 GHz UWB, or 5G NR in the millimeter wave range.

The concept is made possible by the Universal Switch Matrix (UMX), an 8×32 RF switch matrix with integrated DC load emulation and voltage/current measurement block. It ensures the collective use of measurement devices and the planning of individual measurement tasks. The switch matrix connects the active antennas at all times. It can also apply loads or simulate faults. It is specifically designed for high numbers of antennas and large quantities. Furthermore, the UMX offers future expansion options and covers modern technologies such as C-V2X, 5G, 802.11ax, BLE, and UWB.
