CALCulate:MATH<m>:FFT:FRAMe:OFACtor <OverlapFactor>
Defines the minimum factor by which two neighboring frames overlap. If the required
number of frames to cover the input values allows for more overlap, the factor is
increased.
The higher the overlap factor, the more frames are used. This leads to more individual
results and improves detection of transient signal effects. However, it also extends the
duration of the calculation.

CALCulate:MATH<m>:FFT:GATE:COUPling <GateRBWCoupling>
Defines the behaviour of the record length or RBW value in dependancy to the other
FFT parameters.

Parameters:
<GateRBWCoupling> LENGth | RBW
LENGth
The record length remains constant. If not enough samples are
available for the selected RBW, the RBW will be decreased.
RBW
The RBW is not adapted, i.e. remains as defined by the user.
The required acquisition time for this RBW is indicated. If neces-
sary and possible, the record length is extended to acquire the
required number of samples.
