an EMC disturbance which you are required to assess. CISPR 15 used, if I remember correctly, to refer to CISPR 14 for the measurement of clicks. It doesn't do that now, but for Europe you can still apply the provisions of EN 55014-1 if they allow your product to pass. In other words, you

Thank you very much, John. One more question: What is the role of CISPR 16 series to CISPR family standards, such as CISPR 15? For example, I though disturbance voltage measurement mentioned in CISPR 15 should follow CISPR 16-2-1. From what I have learned from you, it seems CISPR 16 series are

Dear Members, Are vertical and horizontal groundplanes required for measuring disturbance voltages per Section 4.3 of CISPR 15? CISPR 15 doesn't mention any groundplane while CISPR 22 does. My colleague concludes that groundplanes are not required. Do you agree with the conclusion?

Hi all I got a question about the magnetic measurement per CISPR 15, it says that the sensitivity of the current probe is 1V/A. My interpretation is that X dBuV measurement you got from the EMI receiver, corresponding to XdBuA, which is then compared to the limit, say 88dBuA at 50 kHz for 2
