Specialized on a validation test environment, where multiple units are tested in parallel for long time periods enduring different environmental factors, but also for development or production scenarios, NOFFZ Technologies GmbH has created a turn-key solution for modern automotive units with high channel count and high technology bandwidth – the UTP 7033 RF Rack.
Core components of the test rack are the NOFFZ sUTP 5018 Base Station Emulator (with optional WLAN/BT/BTLE and V2X/C-V2X extensions) for parallel cellular signaling testing, the NOFFZ sUTP 5017 GNSS Simulator for positioning signal streaming and theUWT for high channel counts with included antenna diagnosis functionalities from Becker Nachrichtentechnik GmbH.
Modern automotive units already cover the newest technologies and standards all at once which need to be tested. Typical are two network access devices (DSDA) for cellular communication up to 5G new radio, at least one device for global positioning (GNSS including RTK), one or two V2X/C-V2X devices and multiple devices for connectivity and wireless network access (WLAN/BT/BTLE). The amount of different communication devices on a single automotive unit and the development of multi-antenna technologies (MIMO) increase the number of RF channels that derive from the devices to the automotive unit’s connectors. New physical connection interfaces like a quad-mini-FAKRA allow a high channel count occupying only small spaces resulting in overall RF interface numbers of currently up to sixteen per unit under test.
