[SENSe:]DEMod:FFT:OFFSet <Mode>
This command specifies the FFT start offset.
Parameters:
<Mode> AUTO
The FFT start offset is automatically chosen to minimize the
intersymbol interference.
GICenter
Guard Interval Center: The FFT start offset is placed to the cen-
ter of the guard interval.
PEAK
The peak of the fine timing metric is used to determine the FFT
start offset.
