Field or control Description
Math n = Lists the last-accessed advanced equation. Tap the down arrow to display a list of the last-accessed
equations (up to a maximum of 20) created by the Equation Editor. Select an equation to display that
math waveform.
T
ap Edit to open the Equation Editor to edit the displayed equation. You can also double-tap on an
equation in this field and directly edit the equation using the virtual keyboard. See Equation Editor
(Math configuration menu) on page 177.
Available when Math Type is Advanced.
Edit Opens the Equation Editor to create advanced math waveforms from analog channels, reference,
math waveform, measurement, and variable sources.
Tap the Edit button to open the Equation Editor. See Equation Editor (Math configuration
menu) on page 177.
Available when Math Type is Advanced.
Math waveform guidelines
•
You can take measurements on math waveforms in the same way as on channel waveforms.
• Math waveforms derive their horizontal scale and position from the sources in their math expressions. Adjusting these controls for the
source waveforms also adjusts the math waveform.
• You can Zoom on math waveforms.
Equation Editor (Math configuration menu)
Use the Equation Editor to build your advanced math waveform expression using sources, operators, constants, measurements, and
functions.
To access the math Equation Editor:
1. Double-tap a Math waveform badge. If no Math badge is present, tap the Math Ref Bus > Add New Math on the Setting bar to add a
Math waveform and open the configuration menu.
2. Set Math Type to Advanced.
3. Tap Edit to open the Equation Editor.
Equation Editor menu fields and controls
Field or control Description
Sources Lists all available sources that you can add to an equation. Tap a source icon to add it to the cursor
position in the Math x = input box. Drag the sources field up or down to scroll through selections.
If a source column is empty
, there are no active or defined sources for that category.
Functions Select the math functions to apply to your signal or signals. See Add Functions (math Equation Editor)
on page 178.
Keypad Use to enter numeric, basic math operations, and logic conditions.
Math <x> = The field that lists the equation components that you add with the equation controls for the numbered
Math waveform. You can also directly edit this field.
Clear Clears the math equation field.
