Hi Larry,
That is what I am looking for. That 15.205 is only for 15.209 radiated emissions and that 15.205 is not applicable to 15.207 conducted emissions. KDB 174176 D01 Line Conducted FAQ v01r01 notice, Q5 details the RF output port configuration of intentional radiators when making AC power-line conducted emission measurements. For devices operating below 30MHz, the RF output can be terminated with a dummy load or network which simulates the antenna.

Richard, It depends, so if we are speaking about an intentional radiator that operates in the 13.56 MHz band under FCC Part 15.225 Subpart C then for the conducted emissions you would use a dummy load in place of the antenna and verify compliance under FCC P15.207 in the operational band. Is that what you are specifically after? Also the restricted bands are for radiated emissions under 15.205, which would follow the 15.209 limits for an intentional radiating device, the restricted bands do not exempt 15.207 conducted emissions. A good resource for your how do you test it questions is most likely found in ANSI C63.10 2013 as that speaks to using a dummy load, etc. also searching the FCC KDB (Knowledge DataBase) and see if your question has already been asked and answered based on a previous inquiry which can be done here. https://apps.fcc.gov/oetcf/kdb/index.cfm Larry K.

Greetings all, I am trying to clarify the application of the FCC 47 CFR Part 15.205, Restricted Bands of operation. Part 15.205 specifies that only spurious emissions are permitted in the frequency bands that are listed in the table. That would mean that intentional radiator frequencies could exceed the conducted (Part 15.207) and radiated (Part 15.209) limits that are not in the restricted bands. Is this a correct interpretation? For example: For the consecutive bands of 13.36MHz to 13.41MHz and 16.42MHz to 16.423MHz that the spurious emissions are permitted, there is a band of 13.41MHz to 16.42MHz, not inclusive, that a 13.56MHz intentional radiator frequency can exceed the conducted limit. Is this a correct interpretation? If not, why not? There are 64 such bands from 9kHz to 36.5GHz. So if one was to plot the bands, it would look like a picket fence. Any assistance and guidance would be most appreciated.
