Rohde & Schwarz shows test equipment for networked cars

June 08, 2015 // By Jean-Pierre Joosting
Rohde & Schwarz will be showing its test and measurement equipment for the automotive market at the Automotive Testing Expo 2015 in Stuttgart.

One of the highlights is the company's system for testing in vehicle emergency call systems. Based on an EU decision, eCall will be mandatory in all new car models from April 2018. ERA-Glonass, which is the Russian equivalent, was launched in spring 2015.

The eCall/ERA-Glonass conformance test system from Rohde & Schwarz is a fast, reliable system for standard-compliant tests of the mobile radio and GNSS-capable components of these in-vehicle systems (IVS). The setup, which consists of the CMW500 wideband radio communication tester with the CMW-KA094/KA095 application software and the GNSS-capable SMBV100A vector signal generator, makes it possible to test whether an IVS modem can successfully make an emergency 112 call and establish a connection with the public safety answering point.

Modern infotainment systems that combine car radio, navigation system, handsfree equipment, mobile Internet and other features have increased the number of transmitters and receivers inside cars and their complexity. Signals for cellular standards such as LTE, noncellular signals such as WLAN and Bluetooth as well as broadcasting signals must not interfere with each other. For the simulation of diversity reception, particularly in the case of broadcast signals, the company will present its BTC broadcast test center. Using two independent realtime signal paths and up to eight arbitrary waveform generators, the BTC generates all of the required RF signals for international TV and broadcast standards, including the relevant interferer signals.

For driver assistance systems, Rohde & Schwarz will be presenting its innovative test system for the development and production of automotive radar sensors. The turnkey ARTS radar target simulator from ITS and miro-sys now features a reduced simulated minimum distance of 6 m and an increased bandwidth of 1 GHz. As a result, it offers ideal characteristics for testing autonomous emergency braking (AEB) systems or blind spot detection, for example. In addition, the realtime interface for hardware-in-the-loop (HiL) simulators can reproducibly play back test scenarios from the field in the lab in line with Euro NCAP standards, reducing development costs and time to market. The perfect addition to ARTS is the FSW high-end signal and spectrum analyzer with its FSW-K60C analysis option for FMCW chirp signals. Its optional analysis bandwidth of up to 2 GHz makes it possible to demodulate and thoroughly analyze even extremely broadband signals.
