At CES 2023, Rohde & Schwarz is presenting its R&S ATS1500C radar test chamber, which is a complete test solution for interference and RF performance testing of automotive radar sensors that enable autonomous driving. Also featured will be an ultra-wideband (UWB) testing solution for smartphone and automotive applications using the R&S CMP200 radio communication tester in combination with the R&S ATS800R anechoic chamber.

With the enhanced R&S ATS1500C antenna test system, developers of automotive radar modules can conduct the complete suite of validation tests necessary prior to volume production. It offers full transmitter and receiver measurements as well as interference immunity tests. Additional features include a new temperature test option and a new feed antenna.

The new R&S ARC-TEMP temperature test option enables temperature-controlled measurements over a wide temperature range from -40 to +85°C within the chamber, saving time and expense compared with heating and cooling the radar module in a separate climate cabinet. Furthermore, the R&S ARC-FX90 universal feed antenna enables parallel access to vertical and horizontal polarizations.

The fine-ranging and security capabilities of UWB technology make it very well-suited for automotive applications such as vehicle access control, gesture recognition, and child-presence detection. Testing the performance of UWB modules and devices is important in the lab and on the production line to ensure compatibility and correct operation.

In combination with the company's shielded chambers, the R&S CMP200 radio communication tester offers a complete solution for transmitter, receiver, time-of-flight (ToF), and angle-of-arrival (AoA) measurements in conducted and radiated mode, compliant with IEEE 802.15.4a/z specifications and able to conduct UWB FiRa certification measurements. AoA is a fundamental characteristic of UWB; measuring it in a controlled and accurate way enables chipset vendors to develop state-of-the-art UWB products for automotive and other applications.

Rohde & Schwarz is presenting its solutions at CES 2023 in Las Vegas from January 5 to January 8, 2023, in West Hall at booth 6757.
