Rohde & Schwarz has developed a setup that enables 3D RF measurements of antenna characteristics in a temperature range from –20°C to +85°C. Integrating the ATS-Temp climate option into an ATS1000 antenna test system makes it possible for the first time ever to combine testing in an RF (OTA) chamber and climatic chamber testing into a single procedure, saving engineer’s measurement time.
Thermal effects diagnostics on devices under test (DUT) are crucial when analyzing the effect of temperature on the chipset and UE performance since device heating or cooling can affect the RF components and consequently the radiation pattern of the antennas. The combination of the R&S ATS1000 and R&S ATS-Temp makes it possible – for the first time in a single testing process – to diagnose temperature effects in addition to the regular over-the-air (OTA) tests. This unique single testing process will be useful for those working with 5G related solutions, e.g. chipset and mobile device manufacturers as well as antenna designers. R&S ATS-Temp is one of the new, comprehensive OTA test solutions from R&S.
Used inside the R&S ATS1000, it allows fast and accurate 3D thermal measurements in extreme temperatures with excellent repeatability and angular resolution. Since the test environment permits significant variations in temperature, it also has several features designed to prevent condensation.
