Field or control Description
Auto Scale Toggles Auto Scale mode on or off. Auto Scale calculates the vertical scale and position to center and
display the entire waveform.
A
vailable when Math Type is Basic or Advanced.
Label Enter a label for the math waveform.
Position Sets the vertical position of the math waveform.
Available when Math Type is Basic or Advanced.
Set to 0 Sets the vertical position of the math waveform to zero (vertical center of a slice (Stacked mode) or the
screen (Overlay mode).
Available when Math Type is Basic or Advanced.
Alternate Units Sets user-specified units to display on vertical scale readouts and measurement badges.
Average Toggles averaging the waveform On and Off. Use averaging to reduce noise on the waveform.
Number of Averages Sets the number of waveform acquisitions to average. Tap and use the assigned multipurpose knob to
set the value.
Available when Average is On.
Math Type Sets the type of math waveform to display.
Basic creates a math waveform by adding, subtracting, multiplying, or dividing two analog waveforms.
FFT opens an FFT view of the specified signal to display the frequency components of that signal.
Double-tap on the FFT view to open its configuration menu.
Advanced displays a drop-down from which to select the 20 last-accessed equations created by the
Equation Editor. This mode also provides access to the Equation Editor. See Equation Editor (Math
configuration menu) on page 177.
Source, Source1, Source 2 Defines the signal source or sources for a Basic, FFT math waveform.
Available when Math Type is Basic, FFT.
Basic math operation list Located between the Source 1 and Source 2 fields. A drop-down list to select a basic math operation
(add, subtract, multiply, divide) to apply to the two sources.
Available when Math Type is Basic.
Interpolation Select to display the record points between the sampled points. Default is unchecked. Available when
Math Type is Basic and Source 1 is Bus. Interpolation uses Sin(x)/x method.
Sin(x)/x connects using a Sin(x)/x curve between the computed values. This makes the gain or phase
curve smoother than linear interpolation.
Field Select the field for the selected bus. Default is Data. Available when Math Type is Basic and Source 1
is Bus.
Signed Data Sets the data as signed decimal. Default is unchecked.
