HV Measurements

Rosenberger’s High-Voltage Test & Measurement Solutions deliver deep insights into the EMC behaviors of high-voltage Automotive Traction Networks. Using our powerful HV measurement coupler, dedicated calibration software and calibration kits, EMC experts can perform RF voltage and current reliability calculations with absolute precision.

  • HPK Measurement Coupler

The newly developed HV Measurement Coupler for HPK series from Rosenberger enables a minimally invasive testing method for measuring the reliability of RF voltages and currents. In conjunction with a dedicated calibration process, patented algorithms accurately calculate the RF currents and voltages in the calibration reference plane.

Furthermore, due to the minimal invasion techniques deployed by the coupler there is no risk of impairment to harness performance when under test. The watertight and robust design also means testing can be carried out under any environmental conditions.   

  • HPK Calibration Kit

Although the HPK measurement coupler includes calibration data, an optional HPK calibration kit is also available. Combined with the RCTD software it enables customers to manage their own calibration requirements themselves. A set of all necessary calibration standards is provided and a description for the acquisition of calibration files is included in the RCTD user manual.

Rosenberger recommends 12-monthly calibration intervals and offers a recalibration service to HPK coupler customers if required.

  • RCTD Software

Rosenberger Calibrated Time Domain Software (RCTD) was developed to enhance EMC-related, automotive high-voltage measurement capabilities. Within the RCTD Software, the time domain data captured by an oscilloscope using the high-voltage coupler is post-processed to calculate high frequency currents and voltages at the given calibration plane within the high-voltage power train. Therefore, calibration data is created and taken into account before measurement occurs.

Delivered on a USB-stick in a sturdy wooden box, the RCTD Software includes the functions to create calibration data and post process the measurement data on a PC or directly on LeCroy HDO oscilloscopes for real-time evaluation. The software can be also used for any other directional coupler.
