Mode ← Vertical Rescaling
Selects the type of horizontal settings:
"Adjust to X
Axis"
The current horizontal settings of the diagram are used.
"Original Scal-
ing"
Horizontal scaling and reference point of the source waveform are
used.
Remote command:
Horizontal Rescaling ← Vertical Rescaling
Stretching and offset change the display of the waveform independent of the horizontal
settings of the source waveform and of the horizontal diagram settings.
Enable ← Horizontal Rescaling ← Vertical Rescaling
If enabled, the horizontal offset and factor are applied to the reference waveform.
Remote command:
REFCurve<m>:RESCale:HORizontal:STATe
Factor ← Horizontal Rescaling ← Vertical Rescaling
A factor greater than 1 stretches the waveform horizontally, a factor lower than 1 com-
presses the curve.
Remote command:
REFCurve<m>:RESCale:HORizontal:FACTor
Position ← Horizontal Rescaling ← Vertical Rescaling
Moves the waveform horizontally. Enter a value with a time unit suitable for the time
scale of the diagram. Positive values shift the waveform to the right, negative values
shift it to the left.
Remote command:
REFCurve<m>:RESCale:HORizontal:POSition

Mathematics
Math waveforms are calculated waveforms. You can define up to eight math wave-
forms and display them on the screen, and use it as source for further analysis.
Math waveforms are defined by mathematical expressions (formulas). You can enter
mathematical expressions using different methods:
●
"Operator" tab: you define a simple math function in a graphical editor by selecting
the source waveforms and the operator.
●
"Equation" tab: you define sophisticated math functions in a formula editor, as
required to your needs.
The result of an FFT analysis is a specific math waveform. For information on FFT and
spectrograms, see
Chapter 9, "Spectrum analysis"
