User’s Guide
- “Real start” and “Real end” specify the range of the X variable (“Real start”
is the X value for the first point of the section and “Real end” is the X value for the
last point of the section).
- “Wave start” and “Wave end” specify the location of the section in the
waveform. These values depend on the waveform length, therefore we recommend to
use “%” function.
The mathematical editor offers the possibility to include two independent constants:
y,z within the expression. The use of these constants is switched on/off by clicking on
the belonging letter placed below the text “Constants”. An edit box with the current
value of the constant is displayed on the right from the letter. The value can be
changed by entering a new value into the field.
If you want to define the waveform of two periods of a sine wave and 0V constant
voltage, you can do so by following these steps:
- create a new waveform (whole waveform is constant 0V)
- define “sin(x)” formula with “Real start” = 0, “Real end” = 4*PI, “Wave
start” = 25% and “Wave end”=75%. This definition changes only the middle section
of the waveform, the rest remains intact. Check the “Normalize” checkbox before
adding the waveform to the list. The normalization flag can be set independently for
each section, but please note, that the normalization parameters are calculated (the
maximum and minimum of the waveform) from all sections, which has this flag on.
