Hi!
I am doing the CE certification test for a module based on CC2652r. The chipset is working under a proprietary protocol based on 802.15.4, with a duty cycle of 6.75%.
The maximum EIRP spectral density calculation formula is as below:
PD= D+ G+ 10 log (1/X)
PD= power density
Duty Cycle= x
G= antenna gain (dBi)
D= measured density on network analyzer
If x= 6.75%, 10 log (1/x)= 11.7dB. The transmitted power level should be set to very low to pass the PSD test of ETSI.
How to correctly calculate the 10 log (1/x) and set the transmitted power level of cc2652r?
