Commands listed in alphabetical order
GROUPDELAY
sets the SpectralPhase units to groupdelay, which computes the
derivative of unwrapped phase spectrum. Units are expressed in seconds.
Examples
MATH:MATH2:SPECTral:PHASE DEGREES
sets the SpectralPhase units for
Math 2 waveform to degrees.
MATH:MATH2:SPECTral:PHASE?
might return
:MATH:MATH2:SPECTral:PHASE RADIANS
, indicating that the SpectralPhase
units for Math 2 waveform are set to radians.
MATH:MATH<x>:SPECTral:SOUrce
This command sets or queries the speci fi ed spectral math source. This only works
with a math of type FFT. The math waveform is speci fi ed by x.

Syntax
MATH:MATH<x>:SPECTral:SOUrce {CH<x>|MATH<x>|REF<x>}
MATH:MATH<x>:SPECTral:SOUrce?
Related Commands MATH:MATH<x>:TYPe
Arguments
Arguments are math sources.
MATH:MATH<x>:SPECTRAL:SOURCE
is for use
when the
MATH:MATH<x>:TYPE
is
FFT
.
Examples
MATH:MATH3:SPECTRAL:SOURCE REF3
sets the source of the Spectral Math
waveform to Ref 3.
MATH:MATH2:SPECTRAL:SOURCE?
might return
:MATH:MATH2:SPECTRAL:SOURCE CH4
indicating the Math 2 spectral source
is Channel 4.
MATH:MATH<x>:SPECTral:SUPPress
This command sets or queries whether suppression threshold for the speci fi ed
math waveform is enabled. This is only applied when Spectral Plot type is Phase.
The math waveform is speci
fi ed by x.
