FCC Part 15 regulates low power, unlicensed devices that could cause interference to the Amateur Radio Service and vice versa.
FCC Part 15 covers an assortment of electronic equipment that generates RF energy whether it's intentional, unintentional or incidental. Amateurs will need to consider Part 15 as it relates to digital devices, computers, low-powered, unlicensed transmitters, electrical devices and any other "generic" device that might generate RF in the normal course of its operation.
Rent, buy, or lease FCC Part 15 test equipment for radiated and conducted emissions measurements. The EMC Shop stocks calibrated equipment.

Conducted spurious emissions that appear at the cable input to the device must meet the following criteria. The input shall be an NTSC video carrier modulated with a 10 IRE flat field with color burst at a level of 0 dBmV and with a visual to aural ratio of 10 dB. The aural carrier shall be unmodulated. The peak level of the spurious signals will be measured using a spectrum analyzer connected by a directional coupler to the cable input of the equipment under test. Spurious signal levels must not exceed the limits in the following table:
The average of the measurements on multiple channels from 450 MHz up to and including 804 MHz shall be no greater than -20 dBmV. Measurements shall be made with the receiver tuned to at least four EIA IS–132 channels in each of the above bands. The test channels are to be evenly distributed across each of the bands. Measurements for conducted emissions caused by sources internal to the device are to be made in a shielded RF room. Measurements for conducted emissions caused by external signal sources shall be made in an ambient RF field whose field strength is 100 mV/m.
