Pulse input precision problem

Dear all,

I try to define a pulse input having a period of 0.01s, and the pulse itself is just 8e-9s.

but when I plot the function I defined, the figure turns out to be strange. It seems that only 1000 points are used to describe the function I defined.

So when I decrease the period to 1e-6s, I can get the right pulse signal as I want.

Could anyone tell me how to increase the precision of the function in COMSOL?

Or is there any other way that I can use to define such a pulse input?

Thanks in advance.
