- math3 = divv(3)*sin (2*pi*t/500) (∗)
The trace obtained is a sine-curve produced using the predefined
function "sin()".
The amplitude is 6 divisions.
The period equal to 500 samples (∗∗) (2 horizontal divisions) depends
on the time base.
•
Same trace produced with the predefined divh() function:
math3 = divv(3)*sin(2*pi*t/divh(2))
In this example, divh(2) is equivalent to 500 samples (∗∗).
The period divh(2), equal to 500 samples (∗∗) (2 horizontal divisions),
depends on the time base.
• Production of a sine wave by the predefined cos() function:
math3 = divv(3)*cos(2*pi*t/divh(2))
The trace obtained with the predefined cos() function is offset by 90°.
math3 = div(3) sin (2pi*t / 10,000) if EXTENDED ACQUISITION MEMORY
option is installed.
