Function: Setting QPSK Decode Phase Shift Di-
rection.
Available Values: NOR / REV
Default Setting: NOR
Description: Sets the phase shift direction during
QPSK reception.
NOR: Normally use this mode.
REV: Inverts the phase of decoding.
QPSK POLARITY TX
Function: Setting QPSK Encode Phase Shift Di-
rection.
Available Values: NOR / REV
Default Setting: NOR
Description: Sets the phase shift direction for
QPSK transmission.
NOR: Normally use this mode.
