Dear Doug,
AFAIK, If the product type is not listed in CCC List. CCC Mark is not
required. This is the mandatory requirement.
If I understand you correctly, you mean if it is not tested, you may feel
uncertain whether it will get into trouble in China. If this is the case,
you may apply for

First convert the limit in Volts to micro Volts, then simply take the log of
that number and multiply by 20.
Example:
1) to convert 1 Volt into dBuV
2) 1 Volt = 1,000,000uV
3) 20log 1,000,000 = 120dBuV
To convert dBuv into Volts just work backwards. Divide 120(dBuV) by 20 (=
6) and take the

Hi
The harmonics limits haven't changed. The method of applying the
limits has changed slightly, but if anything they're easier to meet
now than they were before, so its a reasonable assumption that
your EUT is OK.

dBuV/m = 20* Log (V/m) + 120
V/m = alog([dBuV/m-120]/20)

Derek, I do not believe that there is a harmonized standard that provides
measuring methods
above a gig. However, there is a guidance document that was issued by the

My problem is that immunity test levels in EN 55020 is in dB(uV/m) and EN

Hi all
Is it correct that when measuring with the absorbing clamp (30 - 300 MHz) I
shall not correct for the 17 dB but only for the variation from the 17 dB.
