"dBHz, dBkHz, dBMHz, dBGz"
Logarithmic scaling; related to frequency.
"dBA, dBmA, μdBA"
Logarithmic scaling; related to current.
Remote command:
CALCulate:MATH<m>:FFT:MAGNitude:SCALe on page 1325
Reference level
Defines the reference level for dB scaling.

Vertical scaling mode (Manual/Auto)
By default, the vertical scale is adapted to the current measurement results automati-
cally to provide an optimal display. However, if necessary, you can define scaling val-
ues manually to suit your requirements.
Note: When you change the scaling values manually using the "Scale" rotary knob, the
scale mode is set to "Manual" temporarily. When you edit the math function, scaling is
automatically set back to "Auto" mode. "Manual" mode is only maintained during math
function changes if you select it yourself.
"Manual"
Enter the required values for "Vertical scale" and "Vertical offset". For
FFT, set "Vertical range" and "Vertical maximum".
"Auto"
"Vertical scale" and "Vertical offset" are read-only. For FFT, only the
"Vertical maximum" is read-only.
Vertical range
Defines the range of FFT values to be displayed.
Remote command:
CALCulate:MATH<m>:VERTical:RANGe on page 1229
Range
Defines the vertical value range in spectrum mode.
Remote command:
CALCulate:MATH<m>:FFT:MAGNitude:RANGe on page 1325
Phase unit
Defines the scaling unit for phase display.

Unwrap
If enabled, phase shifts due to a limitation of the value range are eliminated.
