If activated, a diagram for the defined math waveform is displayed on the touch screen.
SCPI command:
CALCulate:MATH<m>:STATe on page 576
Magnitude unit
Defines the scaling of the y-axis. The display values are valid for 50Ω termination impend-
ance.
"Linear"
linear scaling; displays the RMS value of the voltage
"dBm"
logarithmic scaling; related to 1 mW
"dB"
logarithmic scaling; related to reference level
"dBμV"
logarithmic scaling; related to 1 μV
"dBmV"
logarithmic scaling; related to 1 mV
"dBV"
logarithmic scaling; related to 1 V
SCPI command:

Reference level
Defines the reference level for dB scaling.

Vertical scale mode (Manual/Auto)
By default, the vertical scale is adapted to the current measurement results automatically
to provide an optimal display. However, if necessary, you can define scaling values man-
ually 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.
