One of our prototype (IOT gateway) has completed the emission test (EMC) but we have a margin on two particular frequencies, just wondering what is the acceptable margin for CE device in Europe ? I have been through various sites but still not able to figure out this the Margin acceptable. This will be installed at private sites (with public access).
For 160 MHz - Limit=40dBµV/m QuasiPeak=37.20 Margin=-2.80 For 550 MHz - Limit=47dBµV/m QuasiPeak=43.01 Margin=-3.99
Any suggestion would be greatly appreciated !!
