■ Differentiation (Differentiate)
I-V curves and other parameters are frequently differentiated before being processed. In
this system, differentiation is done by one command.
1.
Select Analyse from the menu, then select Differentiate from the pull-down
menu that appears.
2.
Select dl/dV, then select the number of points to use for computing the
differential value.
If you select five points, differential coefficients for five points consisting of the
point of interest and two points on each of the left and right of it are computed.
