Remote probes boost power analyser
Hottinger Brüel & Kjær (HBK) has launched a test system with remote power probes to boost the accuracy of power measurements.
The HBK Fusion Probes aim to boost the accuracy of power measurements in a wide range of applications, including simple electric component testing, dynamic automotive drive cycle testing and complex aerospace copper bird tests. The probes can be used across applications in industrial, automotive and aerospace.
Separating the Fusion Probes from the power analyser receiver card and mainframe, means the probes can be positioned closer to the measurement point, reducing electromagnetic compatibility (EMC) interference significantly. The fibre-optical connection cables and the digital data transfer between probes and mainframe ensure fast and disturbance-free data transfer to the mainframe.
Fusion Probes can be integrated into distributed measurement systems, with modules situated close to the Device under Test (DuT), enabling metres. This makes them ideal for large-scale measurements, as the channel count is scalable from 4 power channels to 68 power channels in a single power analyser mainframe.
The position of the Fusion Probes close to the DuT enables to use ultra short high voltage cables, eliminating intrinsic and emitted noise as well as preventing reflections seen in long cables that can decrease measurement data quality. The fibre-optical connection back to the power analyser is another safety barrier between hazardous high voltages and the user.
The fibre-optically isolated remote probes are available in 4 and 8 power channel packages, with a sample rate of 2 MS/s. These power analyser packages offer an industry-leading accuracy and can be expanded with other inputs for temperature, NVH, or various bus connections. They come with Perception ePower software suite for setup, real-time power analysis, and post processing capabilities.
