Rohde & Schwarz has added three new options for its compact R&S DST200 RF diagnostic chamber: the R&S DST-B160 automated 3D positioner, the R&S DST-B210 cross-polarized test antenna and the R&S DST-B270 communications antenna. The new options significantly speed up precompliance testing of wireless devices, allowing automated test sequences to be performed on the lab bench so that developers no longer require constant access to large RF test chambers.
