Example 4
Focusing 1 cycle of 1 sequence point:
Similar to example 1 but with another 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 created and only
the DC settings will be effective. A ramp with a horizontal progression
is generated.

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 created and only the
DC settings will be effective. Here start and end values are unequal
and a steadily increasing ramp is generated.
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.
Assignment to either U or I makes up to 99 sequence points available for either current or
voltage but not a mix.

Example 7
Focusing 2 cycles of 1 sequence point:
A sequence point, configured as in example
3, is run. Because the settings demand that
the end offset (DC) is higher than the start, the
second cycle will revert to the same start level
as the first, regardless of the values achieved
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
careful choice of settings.
