5G NR FR2 is all about OTA testing since the required AAS do not support RF connectors for conducted testing. But how do you test OTA if multiple AoA are required like in RRM testing for example?
The new R&S®ATS1800M allows for this in a very easy and comfortable way. R&S®ATS1800M is a multi CATR extension to the well known and establishedR&S® ATS1800C compact and protable CATR solution. With the optional side chambers the R&S®ATS1800C grows from one CATR to four such reflectors, each providing a 30cm QZ at the DUT location on the 3D positioner. With this full black-box multi AoA testing with resulting low MU becomes possible on a small footprint.
