Note
• If the user-defined computation option is installed, you must first enter normal computation
mode as described in section 9.1.
• This section describes the setup procedures for computed waveform Math1. Perform similar
steps for Math2.
1. Press the Math1 Setup soft key. The Math1 Setup dialog box opens.
When the user-defined
computation option is installed
2. Use jog shuttle & SELECT to select the operator (+, –, or ∗) and the waveform
on which to perform computation.
When the Math1 Setup dialog box is closed by pressing ESC or another key, the
specified equation appears in the Math1 Setup menu column.
3. Use jog shuttle & SELECT to set the scaling, unit, and smoothing of computed
waveform Math1.
4. Press ESC. The Math1 Setup dialog box closes.
• To exit the menu during operation, press ESC located
above the soft keys.
• In the procedural explanation below, the term
jog shuttle & SELECT refers to the operation of
selecting/setting items and entering values using the
jog shuttle and SELECT and RESET keys. For details
on this operation, see sections 4.1 or 4.2.
• For a description of the operation using a USB keyboard
or a USB mouse, see section 4.3.
Select the waveform on which to perform computation.
Select the operator from +, –, and *.
Set the scaling used to display computed waveform
Math1 to Auto (auto scaling) or Manual (manual scaling).
If scaling is set to Manual, set the vertical center line level
on the screen (voltage value if set to voltage) and the
sensitivity (voltage per division if set to voltage).
Set the unit of computed waveform Math1.
Turn ON/OFF zooming.
