4.4. Radio Test Commands
These Special AT commands are integrated in the B900ss-20 in order to measure in
continuous emission, and are primarily used during radio tests (radiated power, line
width, etc.) to respect the Part15-247 FCC standard.
It stops when any character is sent:
ATT0: Transfer of a pure carrier with the frequency chosen by
the channel command.
ATT1: Transfer of a modulated carrier '00'.
ATT2: Transfer of a modulated carrier '01'.
ATT3: Transfer of a modulated carrier '10'.
ATT4: Transfer of a modulated carrier '11'.
NOTE: the character <CR> follows each command.
