Unit (Unit)
If the computation mode is Math1 to Math4, you can assign a unit to computation results.
• Auto
The default unit is used. The unit varies depending on the computation.
Filter, addition, subtraction, multiplication, or division V, A, VV, AA, VA
Integration Vs, As, VVs, AAs, VAs
Edge count or rotary count Blank
User-defined computation EU
• User Define
You can assign a unit using up to four characters.
Scaling (Ranging)
Select the method used to set the vertical display range of computed waveforms. You cannot set the method
when the source waveform is Ref1 or Ref4.
When using user-defined computation (optional), the method is set to Auto.
Auto (Auto Scaling)
From the computed waveform, the instrument automatically determines the sensitivity (Sensitivity)
2
and the
level
1
at the vertical center (Center) of the screen area.
Manual (Manual Scaling)
Set the sensitivity (Sensitivity)
2
and the level
1
at the vertical center (Center) of the screen area.
1 Voltage for a voltage waveform.
2 Voltage per division for a voltage waveform.
If you change the operator during manual scaling, the instrument changes the display range to the auto
display range that corresponds to the new operator. Ranging remains set to Manual.
User-Defined Computation (User Define, Option)
You can define four original expressions.
User-defined computation can be used only on the 4-channel model.
Expression (Expression)
Define an expression by combining computation source waveforms and operators.
You can enter up to 128 characters.
Computation Source Waveform
The following waveform data can be used.
