Multi CATR antenna test range ATS1800M

For 5G NR FR2 devices, testing must be over the air since there are no RF connectors for conducted testing. But how do you test OTA if multiple signals at multiple angles of arrival are required like in RRM testing for example? The new R&S®ATS1800M provides a solution.R&S® ATS1800M is a multi compact antenna test range (CATR) extension to the established R&S®ATS1800C compact shielded chamber. With the optional side chambers the R&S®ATS1800C grows from one CATR to four , each providing a 30cm quiet zone at the DUT location on the 3D positioner. Full black-box multi angle of arrival testing becomes possible, on a small footprint.
