Refer to FCC MP-5 for information regarding testing at distances other than what is specified in FCC Part 18.

Hi Experts According to FCC part 18.305 FIELD STRENGTH LIMITS, a test article of Any type unless otherwise specified has a measurement distance of 300 meters, but I want to measure it at a distance of 3 meters because I need to measure it in a chamber. In this case, what is the limit at 3 meters? If we use Any non-ISM frequency, the measurement distance is 300 meters and the limit value is 15 uV/m, We have a limit of 63.5 dBuV/m when measuring at 3 meters. However, other laboratories apply a limit of 103.5 dBuV/m. Depending on the RF power of the test device, can I use a 40 log instead of a 20 log conversion? Is the conversion different depending on the power of the test device?
