The AD-6G-1P adapter can be attached to the AEM TestPro ruggedized handheld tester to perform return loss measurements up to 6 GHz on automotive and other coaxial cables. The TestPro introduces a new and innovative test mode for performing Time Domain Reflectometry tests on cables, featuring intelligent and intuitive test limit configurations. This allows car manufacturers to create a custom library of harnesses specific to their vehicles for quick and easy test setup at service centers and on the production line. The test identifies any unexpected ‘events’ along the length of the cable, such as kinks, and provides a simple PASS/FAIL result based on a combination of frequency-based and time domain measurements. Additionally, the visualization of the location of anomalies in the cable and known connector locations makes it easy for technicians to quickly and accurately pinpoint issues in the harness to begin repairs. The compact, portable form factor of the TestPro allows car manufacturers to troubleshoot wire harnesses while installed in the vehicle, providing a distance-to-fault reading to pinpoint the fault location without needing to remove the harness.
The K6GVNA-KIT is a manufacturing test solution featuring a 6 GHz 4-port Vector Network Analyzer. This system works similarly to the existing MMVNA and integrates seamlessly with the VNA Manager Pro software. Leading automotive harness manufacturers have been using the MMVNA for end-of-line testing on harnesses for many years. With the extended frequency range of 6 GHz, harness makers can now accurately test next-generation Single Pair Ethernet or other high-speed cabling. Users can set test configurations depending on the harness construction, define test limits on any or all S-parameters, perform measurements, and produce intuitive test reports. Multiple testers can work together seamlessly to test larger numbers of test ports.
“With increasing autonomous functioning of vehicles, the data cables in the automotive harness must meet stringent requirements for RF performance. Any undetected cable issue can have potentially catastrophic consequences,” said Lisa Schwartz, Director of Marketing at AEM. “The test solutions available today are not suitable for high-volume manufacturing or installed harness troubleshooting needs. The availability of these new test adapters and software from AEM closes this gap.”
