a. Dirty TX is On.
b. BLE TX power can be increased to compensate for front-end losses such as BPF, diplexer, switch, etc.). The
output is capped at 12 dBm out. The BLE TX power at the antenna port cannot exceed the 10 dBm specification
limit.
c. At least 99.9% of all delta F2 max. frequency values recorded over 10 packets must be greater than 185 kHz.
