Certification Notes
FCC RSE certification has both peak and average value requirements. RSE average value must be obtained by DCCF (Duty Cycle Compensation Factor) conversion. The operating instructions are briefly described below.
- Set GRDirect Test Mode Tool as required to make the Bluetooth LE module output power based on preconfigured conditions.
Figure 2 GRDirect Test Mode Tool configuration reference - Channel: Select the channel to be tested (0 – 39).
- Data_Len (Byte): Byte length setting; select 255 (maximum).
- Packet_Payload: Data type setting; select PRBS9.
- PHY: Options include 2 M/1 M/500 K/125 K; select 1 Mbps PHY.
- Power (dBm): Power setting (unit: dBm); selecting 0 means TX power is 0 dBm.
- Station: Select Low. Setting PHY to 1 Mbps PHY corresponds to a duty cycle at 11%; setting PHY to 2 Mbps PHY corresponds to a duty cycle at 8%.
- Measure RSE peak value. For details, refer to "FCC RSE Peak Value Measurement".
- According to RSE peak value test result and DCCF conversion, the RSE average value (refer to "FCC RSE Average Value Measurement") and calculation description should be written into the lab certification report, examples are as follows.
