How to read the UN Regulation No. 10 radiated-emission reference
User task
Use this page for the R10 vehicle radiated-emission reference, where the broadband and narrowband rows answer different receiver questions. The 10 m geometry, detector, bandwidth, scan step and dwell conditions must be read as one setup.
Choose before comparing
Confirm that the result is the vehicle radiated-emission context and retain the 10 m separation before reading a margin. The 30–1 000 MHz reference uses dBµV/m, 120 kHz receiver bandwidth, 50 kHz maximum step and 5 ms minimum scan time; broadband quasi-peak and narrowband average are separate.
What the displayed rows mean
- Vehicle geometry and unit
- The reference is a 10 m vehicle radiated-emission comparison from 30–1 000 MHz in dBµV/m.
- Detector and bandwidth
- Broadband uses quasi-peak and narrowband uses average in the encoded context; the receiver bandwidth is 120 kHz and must stay with the method.
- Scan conditions
- A 50 kHz maximum step and 5 ms minimum scan time describe receiver coverage conditions; they are not extra field-strength limits.
Common misread
The 10 m value, 120 kHz bandwidth, 50 kHz step and 5 ms scan time are a measurement context, not four independent limits. Do not transfer them to a charging-port CE test or silently change the vehicle geometry.
Reference boundary
EMCCalc summarizes the UNECE Regulation No. 10 source register and the encoded R10.05 receiver context. The applicable revision, annex, approval plan and complete legal measurement method remain authoritative.
