Example 1
Focusing 1 cycle of 1 sequence point:
DC values for start and end are the same, also the AC amplitude.
With a frequency >0 Hz a sine wave progression of the set value is
generated with a defined amplitude, frequency and Y axis offset (DC
values for start and end).
The number of sine waves per cycle depends on the sequence point
time and the frequency. If the time was 1 s and the frequency 1 Hz,
there would be exactly one sine wave. If the time was 0.5 s at the
same frequency, there would only be a half sine wave.

Example 2
Focusing 1 cycle of 1 sequence point:
The DC values at start and end are the same but those of the am-
plitude aren’t. The end value is higher than the start value so the
amplitude increases with each new half sine wave continuously over
the sequence point time. This, of course, only if time and frequency
allow for multiple waves to be created. For instance, with f=1 Hz and
time = 3 s, three full waves would be generated, if the angle is 0°,
and reciprocally the same for f=3 s and time=1 s.

Example 3
Focusing 1 cycle of 1 sequence point:
The DC values at start and end are not equal, as well as the AC start
and end values. In both cases the end value is higher than the start
value so that offset increases over time, but also the amplitude with
each new half sine wave.
Additionally, the first sine wave starts with a negative half wave be
-
cause the angle has been set to 180°. The start angle can be shifted
at will in steps of 1° between 0° and 359°.

Example 4
Focusing 1 cycle of 1 sequence point:
Similar to example 1 but with a different end frequency. Here this is
shown as higher than the start frequency. This impacts the period
of the sine waves such that each new wave will be shorter over the
total span of the sequence time.

Example 5
Focusing 1 cycle of 1 sequence point:
Similar to example 1 but with a start and end frequency of 0 Hz.
Without a frequency, no sine wave part (AC) will be generated and
only the DC settings will be effective. A ramp with a horizontal pro
-
gression would result.
