(Option)
This section explains the following settings (which are used when performing user-defined
computations).
• Operators
• Expressions
• Computation conditions
• Labels and units
• Auto ranging
• Scaling
► “User-Defined Computation (User Define, Option)” in the Features Guide
MATH/REF Menu
Press MATH/REF to display the following menu.
Set the expressions.
Set the operator to User Define.
Set Mode to Math.
Set the computation conditions.
Specify the computed waveform
from among Math1 to Math4 that
you want to configure.
Set the label and unit.
Set auto ranging.
Configure the scaling.
Setting Expressions (Expression)
Press the Expression soft key to display the following screen.
Example: Computed waveform Math4
Moves the cursor to
the right
Moves the cursor to
the left
Inserts a right
parenthesis
You can include the automated measurement values
of waveform parameters to expressions.
Define an expression by combining computation source
waveforms and operators.
Deletes the character

Enters the expression
Deletes the previous
character
Deletes all the
characters you have
entered
• Computed waveform Math3
