Rohde & Schwarz has developed the first integrated solution for the Taiwan Space Agency (TASA) combining electromagnetic compatibility (EMC) and antenna measurements in a single chamber. The custom-built system addresses complex satellite payload testing requirements driven by the growing adoption of Non-Terrestrial Network (NTN) technologies.

Satellite payloads increasingly require validation under conditions that simulate both their electromagnetic environment and antenna performance. Traditionally, these measurements are performed in separate facilities, creating logistical and calibration challenges. TASA’s requirement for a single chamber capable of both EMC and antenna measurements prompted Rohde & Schwarz to design a fully integrated system now operational at TASA’s facility.

The solution incorporates an R&S ZNA43 vector network analyzer, customized R&S AMS32 measurement software, and engineering services from Rohde & Schwarz. A Compact Antenna Test Range (CATR) reflector — developed with a Taiwan-based third-party supplier — enables high-precision antenna measurements in confined spaces.

A patented diamond-shaped reflector design is a key feature of the system, reducing internal chamber interference and minimizing interactions between the reflector, feed, and Device Under Test (DUT) positioner. This results in improved accuracy for complex payload measurements.

By integrating EMC and antenna testing capabilities, the system allows TASA to streamline its validation processes, ensuring that satellite payloads meet the performance demands of emerging NTN applications. These include seamless interoperability between satellites and terrestrial cellular base stations — a capability increasingly critical for global communications, remote sensing, and mobile connectivity.

Rohde & Schwarz emphasizes that the project showcases its ability to integrate third-party components while meeting strict performance and reliability standards. The collaboration between TASA, Rohde & Schwarz, and local industry partners demonstrates the adaptability required in advanced satellite testing.
