Sierra Wireless selects innovative R&S ATS1800C test chamber with gold reflector for 5G NR FR2 testing

01/14/2020

Test and measurement is moving from conducted testing to over-the-air (OTA) testing, especially in 5G NR due to the increased frequency range. One challenge of OTA testing is to maintain a compact test chamber size while providing a large quiet zone (QZ), or useable measurement area, in a wide frequency range. Rohde & Schwarz developed the R&S ATS1800C to combine all this, meeting current and upcoming requirements for 5G NR OTA testing.

The R&S ATS1800C is a turnkey, high-end chamber with a small footprint of only 1.3 m². Thanks to its movable design, it is highly flexible and transportable, allowing the chamber to be easily moved from one lab to another. The solution provides a large quiet zone of 30 cm, fulfilling 3GPP 5G NR conformance test requirements. With its high shielding efficiency, the R&S ATS1800C is designed to provide a trouble-free environment for uninterrupted measurements of 5G antennas, modules and devices.

A unique characteristic of the R&S ATS1800C is its state-of-the-art gold CATR reflector, transforming the incoming spherical wave front to a plane wave. Manufacturing the reflector requires processes that are accurate in the micrometer range. To achieve such high precision, Rohde & Schwarz has developed an innovative manufacturing method, delivering high quality reflectors reproducibly.

The R&S ATS1800C supports the testing of devices weighing up to 8 kg, which makes it well suited for testing a variety of active or passive DUTs, from small chip modules to tablets and laptop or even small cells. Hardware triggering allows measurements during continuous movement of the high-precision 3D positioner, which can reduce measurement time by a factor of 5 to 10.
