CATR based compact and mobile anechoic chamber for mmWave 5G OTA testing
The R&S®ATS1800C CATR based 5G NR mmWave test chamber provides the ideal environment for testing 5G FR2 antennas, modules and devices over the air (OTA) from R&D to conformance. With its small footprint and wide frequency range, the R&S®ATS1800C offers great functions and test coverage in a very small space. With its flexibility and broad range of extension options, the R&S®ATS1800C offers a solid and future-proof environment for your FR2 testing needs.
A convenient test environment
The compact, fully shielded R&S®ATS1800C has a footprint of only 1.3 m2 and a large quiet zone of 30 cm or even 40 cm depending on the selected reflector size. Wheels make the R&S®ATS1800C easy to transport and its compact size can fit through most doors in R&D labs and test houses. It can quickly and accurately test a wide range of 5G DUTs such as modules, smartphones and even laptops and small cells.
R&S®ATS1800C
Accurate IFF measurements with high-quality CATR reflector
The R&S®ATS1800C has a bidirectional parabolic reflector that collimates beams from the feed antenna or DUT. The reflector is specially designed and manufactured by Rohde & Schwarz in Germany for unrivaled performance in a small test chamber. The rolled edges of the reflector are modeled to minimize scattering while the surface is precisely polished, which is critical when operating at high frequencies. Two different reflector sizes are available for two different quiet zone sizes (30 cm or 40 cm).
State-of-the-art CATR reflector
Smooth movements facilitate fast and accurate measurements
With best in class angular resolution and accuracy, the positioner supports heavy DUTs for CTIA FR2 antenna performance testing with phantom heads and hands. The built-in hardware trigger function supports fast measurements and shorter test times. The test time for a full TRP measurement can be reduced by a factor of 5 to 10 (depending on the number of frequencies and angular step size) compared to conventional measurement methods.

Automatic feed switcher to cover a wide frequency range
Out-of-band emissions require measurements outside typical band limits in lower and higher frequency ranges. For seamless measurements, the R&S®ATS1800C can be equipped with an automatic feed switcher for up to four different selectable feed antennas on motorized movers supporting 6GHz to 110GHz. Single fixed feeds are also available for measurements in frequency ranges other than the major 5G FR2 frequency bands from 12GHz up to D-Band (170GHz).

Unique solution with four high-end reflectors for RRM testing and beyond
The DUT needs to receive 5G NR signals from different angles for radio resource management (RRM) testing. At least four different signal directions are required in different combinations for the specified five relative angles between the signals. The unique side chamber extension of the R&S®ATS1800C can create a 30 cm quiet zone for signals from each additional direction and ensures the lowest measurement uncertainty even in complex test scenarios.

Camera option with additional smart features
Since the R&S®ATS1800C is fully sealed during testing, it is hard to see the device or check what is happening inside the chamber. The camera option lets you monitor the DUT at all times. Heat dissipation on 5G mobile devices is a potential issue so the camera can easily switch to infrared vision for checking the DUT heatmap while testing.

Highly capable and flexible test chamber
Designing a module in the lab? Running conformance test cases together with the R&S®TS8980 in a test house? Applications and requirements differ but all these jobs can be done with a single test chamber. The 3GPP 5G NR compliant R&S®ATS1800C helps optimize the overall performance of RF modules, including beam characterization measurements.
