Rohde & Schwarz has introduced a new R&S DST200 RF diagnostic chamber that enables OTA performance and RSE testing of wireless devices right on the lab bench. Results are comparable to those of large RF test chambers over a wide frequency range, 700 MHZ to 6 GHz. The anechoic RF chamber has highly effective shielding at greater than 110 dB for interference-free testing in unshielded environments
