Additionaltesting,Part15subpartBdisclaimer
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.
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.
Frequency spectrum to be investigated
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.
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 general testing details.
The product under test is placed into a normal “paired” mode with another Bluetooth device, as
per the normal intended use of the product. For example, data transfer, music playing, etc.
