BLAckman Blackman window
Return parameter Returns the FFT window.
Example :MATH:FFT:WINDow HAMming
Sets the FFT window filter to hamming.
:MATH:FFT:POSition
Description Sets the vertical position of the displayed FFT
result.
Syntax MATH:FFT:POSition { <NRf> | ? }
Parameter <NRf> Vertical position: -12e+0 to +12e+0
(12 units/division to +12 units/division.)
Return parameter <NR3> Returns the vertical position.
Example :MATH:FFT:POSition -2e-1
Sets the FFT position to -0.2 divisions.
:MATH:FFT:SCALe
Description Sets the vertical scale of the displayed FFT result.
Syntax :MATH:FFT:SCALe {<NRf> | ?}
