- BMW GS 95025-1
- GB/T 18655-2018
CISPR 25 is a standard number that applies to any electronic/electrical component on vehicles, boats, and internal combustion engines used for testing radio nuisance testing of vehicles, trailers, and installations to protect adjacent receivers on board the vehicle in proper working order. The name of the standard is: Vehicles, boats and internal combustion engines Radio disturbance characteristics Limits and methods of measurement for the protection of on-board receivers Vehicles, boats and internal combustion engines-Radio disturbance characteristics -Limits and methods of measurement for the protection of on-board receivers
Our standard GB 18655 is the Chinese translated version of CISPR25.
Test Utilization Notes:
The main application of the NNHV 8123-400 is the measurement of interference voltages in the HF-VHF range 0.1 MHz - 150 MHz using shielded cables for the testing of electric vehicle components according to the EMC test standard for automotive electronics: CISPR 25 Ed.4 version or BMW GS 95025-1.
Using this AN with our 50 Ω load terminals, it is also possible to perform BCI tests with high current injection. The impedance characterization circuit principle is 5 μH || 50 Ω and is realized by connecting the inductor in parallel with the input impedance of the measurement receiver.
Circuit Schematic for NNHV 8123-400
For testing, each NNHV 8123-400 needs to be mounted in a high voltage shielded box HVSE 8600 as per standard requirements, each AN can be used to measure a single path, so to be able to measure high voltage + and high voltage - bipolarity you would need to source two identical NNHV 8123-400s. The DUT EUT must be connected to the front panel terminals and the supply voltage must be connected to the rear panel.
