Hello Mario, Thank you for your reply. Perhaps I asked the wrong question. We have an intentional radiator with a 10th harmonic of the oscillator that is less than 300 MHz, but the switch mode supply generates impulses measured in the 5 GHz region. We have been told that the product is "noisy" by a consultant of the government. What I am trying to determine is if any 5 GHz regulation or standard has been violated. As the noise source is switching noise, I do not believe that an intentional radiator spec in the 5 GHz band would apply. Do you have any thoughts on this? What regulations or standards does Japan have in place for incidental emissions near 5 GHz?

In the actual Japanese standard it is referred to CISPR 22:1997. Kind regards i.V.
