Example 6
Focusing 1 cycle of 1 sequence point:
Similar to example 1 but with a start and end frequency of 0 Hz. With
-
out a frequency no sine wave part (AC) will be generated and only
the DC settings will be effective. Here the DC start and end values
are unequal and a steadily increasing ramp would result.
By linking together a number of differently configured sequence points, complex progressions can be created. Smart
configuration of the arbitrary generator can be used to match triangular, sine, rectangular or trapezoidal wave func
-
tions and thus, e.g. a sequence of rectangular waves with differing amplitudes or duty cycles could be produced.

Example 7
Focusing 2 cycles of 1 sequence point:
One sequence point, configured as in example
3, is run. Since the settings define that the end
offset (DC) is higher than the start, the second
run will revert to the same start level as the
first, regardless of the signal level at the end of
the first run. This can produce a discontinuity
in the total progression (marked in red) which
may only be compensated with a careful choice
of settings.

Example 8
Focusing 1 cycle of 2 sequence points:
Two sequence points run consecutively. The
first one generates a sine wave with increasing
amplitude, the second one with a decreasing
amplitude. Together they produce a progression
as shown to the left. In order to ensure that the
wave peak in the middle occurs only once, the
first sequence point must end with a positive half
wave and the second one start with a negative
half wave as shown in the diagram.

Example 9
Focusing 1 cycle of 4 sequence points:
Point 1: 1/4th sine wave (angle = 270°)
Point 2: Three sine waves (ratio of frequency
to time is 1:3)
Point 3: Horizontal ramp (f = 0)
Point 4: Falling ramp (f = 0)
