I don't see that one can tell if it's reasonable or not without a lot more information, which is probably confidential to your company. But there isn't any major effect that occurs just above 18 GHz to make CISPR 16-4-2 no longer a good guide at least. Of course, you need an FAR that has no unacceptable defects at the frequency you are using, and if that is far above 18 GHz, effects such as atmospheric absorption need to be considered.

From: Grace Lin [mailto:[email protected]] Sent: Saturday, October 29, 2016 4:47 PM To: [email protected] Subject: [PSES] Measurement Uncertainty Above 18 GHz Dear Members, Is it reasonable to request measurement uncertainty (MU) above 18 GHz? CISPR 16-4-2 Edition 2.1 seems only up to 18 GHz. Is there any standard that addresses MU above 18 GHz? Is it reasonable to claim that MU is not applicable for radiated disturbance / emission measurement above 18 GHz as there is no site validation standard available for frequency above 18 GHz? Thank you very much and I look forward to hearing from you.
