In-vehicle tests add authentic context to telematics verification

June 10, 2013 // By Christoph Hammerschmidt
Testing of telematics devices is becoming an issue for OEMs and tier-one automotive systems companies. RF testing company IZT GmbH has developed IZT RecPlay, a platform for RF receiver design validation of analogue and digital radio, video and global navigation satellite systems.

The platform features a portable monitoring RF recorder for mobile and telematics applications for accurate phase-synchronous recording of diversity signals from multiple antennae. Customers benefit from the lightweight recorder with a 30-cm high-resolution touch screen as a turnkey solution for in-vehicle testing. The integrated GPS receiver serves as a robust time and location reference. RecPlay's signal generator IZT S1000 combines 31 virtual signal generators in a single platform for testing radio receivers and for creating complex mixed signal RF scenarios.

The system receives, records, and replays up to 20 MHz bandwidth in a frequency range from 9 kHz to 3000 MHz. It supports practically all radio broadcast standards such as FM-RDS, DVB-T, DAB, DAB+, DMB-Audio, Sirius and XM, including DRM/DRM+ and HD radio receivers.
