{RECTANGular|HAMMing|HANNing|BLACKMANHarris}
MATH:MATH<x>:SPECTral:WINdow?
Related Commands MATH:MATH<x>:TYPe
Arguments
RECTANGular
window function is equivalent to multiplying all gate data by one.
HAMMing
window function is based on a cosine series.
HANNing
window function is based on a cosine series.
BLACKMANHarris
window function is based on a cosine series.
Examples
MATH2:SPECTRAL:WINDOW HANNING
applies a Hanning window to the spectral
analyzer input data.
MATH2:SPECTRAL:WINDOW?
might return
:MATH2:SPECTRAL:WINDOW
BLACKMANHarris
, indicating that the window function used to multiply the
spectral analyzer input data is the BLACKMANHarris function.
MATH:MATH<x>:TYPe
This command sets or queries the math type. The math waveform is speci fi ed by x.
Group Math
Syntax
MATH:MATH<x>:TYPe {BASic|FFT|ADVanced}
Arguments
BASic
set the type to basic math.
FFT
sets the type to FFT math, which can use any live analog or reference
waveform in the time domain. NOTE. You can also use FFT as part of a math
expression by declaring the type
ADVanced. See examples for the command MATH:MATH<x>:DEFine .
ADVanced
sets the type to advanced math.
Examples
MATH:MATH2:TYPE BASIC
sets the type of Math 2 to basic.
MATH:MATH2:TYPE?
might return
:MATH:MATH2:TYPE FFT
indicating the
type of Math 4 is currently FFT.
