5 Validation of SiP Radio Conformance as
Implemented in Host
When a host systems copies exactly the antenna trace design, matching component and layout
specified in “QCA6234 SiP Module Certified Antennas and Layout”, there is still a need to
validate that the final product design maintains compliance with radio conformance rules. Minor
electrical variations in PCB trace design, stackup and possible coupling with nearby circuits in
the end system may result in different emissions characteristics compared to the original SiP
design used for standalone modular certification testing performed by Tesla Motors, Inc..
Therefore radiated spurious emissions testing must be performed on each unique host device that
uses a certified SiP.
The host integrator must follow these steps:
w Request a quote from any competent third party test lab for Radiated Spurious emissions
testing including restricted bands per FCC 15.247(d) for 2.4 GHz and 15.407(b) for 5 GHz.
This type of testing may be referred to as “permissive change” testing. However, it is not
normally required to submit the report to the regulator. A Class 2 Permissive Change filing is
Not required and should not be quoted by the test lab. Testing and a report is sufficient.
w Testing may be performed conveniently at the same test lab and at the same time as the FCC
Part 15B, digital emissions testing which is mandatory for every host design. However, the
spurious emission testing normally requires radio test software on the host device.
w It is acceptable and desirable to perform the 15.247 / 15.407 radiated spurious testing early in
the design process - as soon as a final PCB design and functional system is available. This
validation testing need not be done using the final production version, as long as PCB and RF
design is not modified.
w The third party lab report showing 15.247 / 15.407 compliance must be submitted toTesla
Motors, Inc.s using the email address:

Please contact your Tesla Motors, Inc. Account Representative or email any questions to above
email address for assistance preparing for the Radiated Spurious emissions testing. Tesla Motors,
Inc. can provide further instructions if the OEM Integrator is not familiar with the Tesla Motors,
Inc. test software used to support radio testing.
