Chip Rate
NOTE
This parameter is available when Radio Std is 802.11b/g(DSSS/CCK/PBCC).
This specifies the fundamental chip rate of the signal to be analyzed. The value
should be positive, and default is 11 MHz, which matches the chip rate of
802.11b/g.
The only special case is the optional 802.11g 33Mbit PBCC mode. In this mode, the
chip rate of the transmitted signal starts at 11 MHz, but changes to 16.5 MHz in the
middle of the burst. For signals of this type, the CHIP_RATE should still be specified
as 11 MHz, and the measurement will automatically switch to 16.5 MHz at the
appropriate place in the burst.
