Example:
Production of a damped sinusoidal trace
from predefined functions
math1 = sin (pi*t/divh(1))*exp(-t/divh(6))*divv(4)
"sin (pi*t/divh(1))" changes the number of periods.
"exp (-t/divh(6))" changes the damping level.
Definition of a
complex function

digital keypad and
a field that can be
parameterized
8 predefined mathematical functions can be used:

Divh (

"horizontal division"

Divv (

"vertical division"

Step (

() t = abscissa of the sample in the acquisition
memory divh(1) is equivalent to 10,000
samples (points) = 1 horizontal div.
