8. Add the appropriate maximum ground reflection factor to the EIRP level (6 dB for frequencies ≤ 30 MHz,
4.7 dB for frequencies between 30 MHz and 1000 MHz, inclusive and 0 dB for frequencies > 1000 MHz).
9. For devices with multiple antenna-ports, measure the power of each individual chain and sum the EIRP
of all chains in linear terms (e.g., Watts, mW).
10. Compare the resultant electric field strength level to the applicable regulatory limit.
11. Perform radiated spurious emission test duress until all measured frequencies were complete.

6.8.5. Test Results

Please refer to Appendix A.8

Remark:
1. Measured at difference Packet Type for each mode and recorded worst case for each mode.
2. Worst case data at DH5 for GFSK, 2DH5 for π/4DQPSK and 3DH5 for 8DPSK modulation type;
3. Measured at Hopping and Non-Hopping mode, recorded worst at Non-Hopping mode.
4. The other emission levels were very low against the limit.

6. Detector AV is setting spectrum/receiver. RBW=1MHz/VBW=330Hz/Sweep time=Auto/Detector=Peak;
7. Since the out-of-band characteristics of the EUT transmit antenna will often be unknown, the use of a
conservative antenna gain value is necessary. Thus, when determining the EIRP based on the
measured conducted power, the upper bound on antenna gain for a device with a single RF output shall
be selected as the maximum in-band gain of the antenna across all operating bands, or 2 dBi, whichever
is greater. However, for devices that operate in multiple frequency bands while using the same transmit
antenna, the highest gain of the antenna within the operating band nearest in frequency to the restricted
band emission being measured may be used in lieu of the overall highest gain when the emission is at a
frequency that is within 20 percent of the nearest band edge frequency, but in no case shall a value less
than 2 dBi be used.

Note: The antenna gain of the complete system is calculated by the difference of radiated power in
EIRP and the conducted power of the module. For normal Bluetooth devices, the GFSK mode is used.
