Enable Math Signal
If activated, a diagram for the defined math waveform is displayed on the touch screen.
SCPI command:
CALCulate:MATH<m>:STATe on page 576
Vertical Scale
Functions to set the vertical parameters of the math waveform.
Note: If an FFT expression is defined, the vertical scaling for spectrum displays is avail-
able: "Vertical maximum" and "Vertical range" instead of "Vertical Scale" and "Vertical
Offset". See chapter 6.3.3.2, "FFT Magnitude/Phase", on page 202.
Vertical scale mode (Manual/Auto) ← Vertical Scale
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.
Vertical Scale ← Vertical Scale
Defines the scale of the y-axis in the math function diagram. The value is defined as
"<unit> per division", e.g. 50mV/div. In this case, the horizontal grid lines are displayed
in intervals of 50mV.
If the Vertical scale mode (Manual/Auto) is set to "Auto", this setting is read-only.
SCPI command:
CALCulate:MATH<m>:VERTical:SCALe on page 577
Vertical Offset ← Vertical Scale
Sets a voltage offset to adjust the vertical position of the math function on the screen.
Negative values move the waveform au, positive values move it down.
If the Vertical scale mode (Manual/Auto) is set to "Auto", this setting is read-only.
SCPI command:
CALCulate:MATH<m>:VERTical:OFFSet on page 576
Arithmetic
Functions to specify the waveform arithmetic for the math waveforms.
Reset Now ← Arithmetic
Forces the immediate restart of the envelope and average calculation for all waveforms,
ignoring the reset settings.
