6.5.3. Mathematical operation
“Plot view” also provides some math formulas for the operation of physical quantities, such as
the integration, differentiation, addition, multiplication,…, etc. This allows users to calculate
and observe the calculated result directly in “Plot view”. In addition, it also provides the
maximum, minimum, ripple calculation, and spectrum analysis of each physical quantity.
(1) Statistics table
Click to display the table as shown in Fig. 6-18. It shows the maximum, minimum,
average, root mean square (rms), Rip, and RipA of each physical quantity within the
interval selected by cursors, as shown in Fig. 6-18. Here,
Rip = standard deviation/average,
RipA = (maximum - minimum) /average.
The related icon on the main toolbar area is described as follows.
- : The maximum, minimum, root mean square (rms), and ripple calculation of
physical quantity.

(2) Mathematical operation method
Select “Math operation” of “Tools” in the function menu or click to open the window of
Fig. 6-19 to do a proper methematical operation. Here, take the addition as an operation
example. After clicking the option of “Linear”, choose “pos_err” and “vel_fbf” via the
drop-down menu. Then, name the new physical quantity in the “New plot name” field and
