general testing details.
FCC Statement
Any Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment. This device complies
with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and (2) This device must accept any
interference received, including interference that may cause undesired operation
Operating the host product
When testing the host product, all the transmitters must be operating.The transmitters can
be enabled by using publicly-available drivers and turned on, so the transmitters are
active. In certain conditions it might be appropriate to use a technology-specific call box
(test set) where accessory devices or drivers are not available.
When testing for emissions from the unintentional radiator, the transmitter shall be placed
in the receive mode or idle mode, if possible. If receive mode only is not possible then, the
radio shall be passive (preferred) and/or active scanning. In these cases, this would need
to enable activity on the communication BUS (i.e., PCIe, SDIO, USB) to ensure the
unintentional radiator circuitry is enabled. Testing laboratories may need to add
attenuation or filters depending on the signal strength of any active beacons (if applicable)
from the enabled radio(s). See ANSI C63.4, ANSI C63.10 and ANSI C63.26 for further
The product under test is set into a link/association with a partnering WLAN device, as per
the normal intended use of the product. To ease testing, the product under test is set to
transmit at a high duty cycle, such as by sending a file or streaming some media content.
