CC2550
The fraction of a symbol period used to
change the phase can be modified with the
DEVIATN.DEVIATION_M setting. This is
equivalent to changing the shaping of the
symbol. Setting DEVIATN.DEVIATION_M=7
will generate a standard shaped MSK signal.
The MSK modulation format implemented in
CC2550 inverts the sync word and data
compared to e.g. signal generators.
21.3 Amplitude Modulation
The supported amplitude modulation On-Off
Keying (OOK) simply turns on or off the PA to
modulate 1 and 0 respectively.
