Regarding CEPT ERC recommendation 70-03 and ETSI regulation EN 300220
both of the following figures show full compliance in case of ASK and FSK
modulation spectrum. Data signal is a Manchester encoded PRBS9 (Pseudo
Random Binary Sequence), RF output power is +9dBm at a supply voltage of
3V. With these settings ASK allows a maximum data rate of 25kBaud, in FSK
case 40kBaud are possible. See also Section 5.1.4
