Automotive test solutions on parade at Stuttgart Expo

The amount of electronics in all vehicles is increasing year on year. Technology is being used to support drivers in critical situations and help them avoid accidents. All these devices need to be tested thoroughly and Rohde & Schwarz will be demonstrating its resources as an industry partner at the international Automotive Testing Expo 2014 in Stuttgart (June 24-26).

The T&M specialist will exhibit its test solutions for wireless applications such as vehicular radar, intelligent transport systems, eCall and automotive Ethernet interfaces.  

Taking centre stage on its booth will be the new R&S TS ITS100 RF conformance test system – a fully automated test system for IEEE 802.11p. It is specifically tailored for standard compliant component testing for vehicle-to-vehicle (V2V) applications and intelligent transport systems. Its R&S Contest RF conformance test sequencer software does more than verify compliance with regional standards such as ETSI EN 302 571 in the EU, IEEE 802.11 2012 in the United States and ARIB in Japan. It also covers the specialised performance tests of the automotive industry. The compact design of the tester enables it to be used in every part of the value added chain from development to pre-compliance and compliance testing.

The R&S FSW high end signal and spectrum analyser enables radar component developers to automatically detect and measure their signals with an analysis bandwidth of up to 500 MHz and display them in both the time and frequency domains.

As a standalone unit the analyser covers the 24 GHz frequency band widely used in automotive radar. It uses external harmonic mixers to analyse signals at 77 GHz.

At Automotive Testing Expo, Rohde & Schwarz will demonstrate the analyser equipped with the R&S FSW K60 option for transient analysis and the R&S FSW K60C extension for FMCW signal analysis. This makes it possible to characterise chirp signals that are typical for automotive radar (with their linear frequency ramps and large bandwidths) according to important parameters such as chirp rate, chirp length and chirp rate deviation

Oscilloscopes will also be on parade at the show. Intense discussion in the industry for years on the use of Ethernet technologies in automobiles has led to BroadR-Reach technology becoming an efficient solution for high speed data exchange, making it possible to combine a number of self- contained applications such as rear view cameras and radar in a single, open and scalable Ethernet network within a vehicle.

OPEN Alliance SIG Standard conformance tests are used to ensure the reliability of BroadR Reach communications. Rohde & Schwarz has addressed this test requirement with a new software option for its powerful R&S RTO oscilloscope (pictured).

The R&S RTO-K24 compliance test software enables users to carry out automated tests on BroadR Reach Ethernet interfaces. Image based instructions provide step by step support during the measurements. Configurations are created automatically, and results are documented in a straightforward test report.
