Vertical maximum
Defines the maximum value on y-axis for spectrum displays. Only available for "Man-
ual" scale mode.
Vertical range
Defines the range of FFT values to be displayed.
SCPI command:
CALCulate:MATH<m>:VERTical:RANGe on page 576
Range
Defines the vertical value range in spectrum mode.
SCPI command:

Unwrap
If enabled, phase shifts due to a limitation of the value range are eliminated.
SCPI command:
CALCulate:MATH<m>:FFT:PHASe:UNWRap on page 588
Suppression
Enables noise suppression. Phase calculation is restricted to frequencies with a minimum
magnitude, the threshold value.
SCPI command:
CALCulate:MATH<m>:FFT:PHASe:SUPPression on page 587
Threshold
Defines the minimum frequency magnitude for which phases are calculated. This setting
is only available if "Suppression" is enabled.
SCPI command:
CALCulate:MATH<m>:FFT:PHASe:THReshold on page 588
