User's Manual

The host integrator installing this module into their product must ensure that the final
composite product complies with the FCC requirements by a technical assessment or
evaluation to the FCC rules, including the transmitter operation and should refer to guidance
in KDB 996369. For host products with certified modular transmitter, the frequency range of
investigation of the composite system is specified by rule in Sections 15.33(a)(1) through
(a)(3), or the range applicable to the digital device, as shown in Section 15.33(b)(1),
whichever is the higher frequency range of investigation 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 50 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
general testing details.
The product under test is set into a link/association with a partnering 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.
9. Additional testing, Part 15 Sub part B disclaimer The final host / module combination
need to be evaluated against the FCC Part 15B criteria for unintentional radiators in order
to be properly authorized for operation as a Part 15 digital device.
