Commands listed in alphabetical order
MATH1:SPECTRAL:UNWRAP?
might return
:MATH1:SPECTRAL:UNWRAP 0
,
indicating that the phase unwrap of the spectral analyzer output data is disabled.
MATH:MATH<x>:SPECTral:UNWRap:DEGrees
This command sets or queries how many degrees adjacent phase values can
jump before being unwrapped. This requires the Spectral type to be Phase and
the
UNWRAP
to be enabled for this PI command to have any affect. The math
waveform is speci fi ed by x.

Arguments
<NR3>
is the value of unwrap phase in degrees.
Examples
MATH:MATH2:SPECTRAL:UNWRAP:DEGREES
90 sets the unwrap phase of the
spectral Math 2 to 90 degrees.
MATH:MATH2:SPECTRAL:UNWRAP:DEGREES?
might return
:MATH:MATH2:SPECTRAL:UNWRAP:DEGREES
180 indicating unwrap
phase of the spectral math 3 waveform is 180 degrees.
MATH:MATH<x>:SPECTral:WINdow
This command sets or queries the window function used to multiply the spectral
analyzer input data for the speci
fi ed math waveform. The Math waveform is
speci fi ed by x. A spectral window determines what the fi lter shape of the spectral
analyzer will be in the frequency domain. It can be described by a mathematical
function that is multiplied point-by-point times the input data to the spectral
analyzer.
Following is a list of arguments that specify the window function used to multiply
the spectral analyzer input data. The windows are listed in the order of their
ability to resolve frequencies (resolution bandwidth).
