Rohde & Schwarz has developed the first integrated testing solution for the Taiwan Space Agency (TASA), allowing for seamless EMC and antenna measurements within a single chamber. The project highlights the growing demand for advanced satellite testing systems as non-terrestrial network (NTN) technologies evolve.
With the increasing adoption of NTN technologies, precise validation of satellite performance in complex environments is essential. This includes ensuring integration between satellites and cellular base stations – an area where conventional testing methods often fall short.
The project’s complexity came from TASA’s dual testing requirement of a single chamber cpable of performing both EMC and antenna measurements. To meet this demand, Rohde & Schwarz’s solution includes a R&S ZNA43 vector network analyser, R&S AMS32 customised measurement software, and engnieering services. In addition, the system incorporated a compact antenna test range (CATR) reflector developed in partnership with a Taiwan third party supplier.
A key innovation in the project was introducing a patented diamond-shaped reflector design. This reflector minimises interference within the chamber and reduces interactions between the reflector, feed, and Device Under Test (DUT) positioner. This results in improved accuracy and reliability in measuring complx satellite payloads.
The collaboration between a third party supplier and TASA highlights the company’s adaptibility in addressing specialised customer requirements while maintaining high standards of performance and reliability.
