Tektronix MSO 2 Series - Add Functions (Math Equation Editor)

Field or control Description
Arrows Use to move the cursor position in the Math <x> = equation field.
Space Use to add the space to the right of the cursor.
Delete Deletes the selected part of the equation (recommend that you use a mouse to more easily select
equation text).
Backspace Deletes the character to the left of the cursor.
Apply Tap to apply the math expression shown in the Math <x> = field and display the math waveform. The
first ~ eight characters of the equation also appears in the Math badge on the Settings bar
.
When the editor detects a logic or syntax error with the equation, the editor displays an error message,
along with the character position in the equation where the editor considers the error to have occurred.
Cancel Closes the editor menu, does not update the equation list if you made any changes from the last time
you Applied or OK'd an equation.
OK Applies the equation to the math waveform, closed the Advanced Editor window, and adds the
equation to the available equation list.
Equation editor guidelines
•
Math definitions are not applied if the sources are not valid.
• Syntax or other equation or source errors display a short error message on the Math configuration menu.
• Use parentheses to group terms in the expression to control execution order, for example, 5*(Ch1 + Ch2).
Add Functions (math Equation Editor)
Use the Add Functions controls to add predefined math operations to your math waveform equation.
Button Description
Integral. Inserts the text INTG( into the math expression. Enter an argument to the function. The integral function
produces the integral of the argument.
Base 10 logarithm. Inserts the text LOG( into the math expression. Enter an argument to the function. The log
function produces the base 10 logarithm of the argument.
Square root. Inserts the text SQRT( into the math expression. Enter an argument to the function.
Absolute. Inserts the text FABS( into the math expression. The FABS function takes the absolute value of the
expression.
Derivative. Inserts the text DIFF( into the math expression. Enter an argument to the function. The derivative
function produces the derivative of the argument.
