DCDP-MTD®
In order to support automotive system integration, Rosenberger provides directional coupler-based measurement techniques as well as probes for comprehensive cross-domain coupling analysis.
  • Separation of uplink and downlink signals on twisted-pair cables for Ethernet systems using a single differential pair.
  • Detection of common mode interferences on unshielded differential wires

 

HPK Measurement Coupler
HPK Measurement Coupler
New accessories and technologies within vehicles, like infotainment, smart dashboards, and various advanced driver assistance systems, have increased the demand for high-speed automotive bus systems working in parallel with the high-voltage power networks in electric cars.

The newly developed HPK Measurement Coupler enables detection of  RF voltages and currents in automotive HV-power train as well as fast transients and single shot events in the HV cable harms. An innovative calibration and post processing software (Rosenberger Calibrated Time Domain Software) for time domain measurements is also available.

RCTD - Rosenberger Calibrated Time Domain-Software
Rosenberger Calibrated Time Domain Software
Rosenberger Calibrated Time Domain Software (RCTD) was developed to enhance EMC-related, high-voltage measurement capabilities.
  • Novel calibration and post processing software for time domain measurements by the use of a directional coupler
  • Minimal inversive measurements of voltages and currents due to the use of directional couplers
