A triangular wave signal for use on the current or voltage is
generated. The positive and negative slope times can be set
independently.
The offset shifts the signal on the Y axis.
The sum of the intervals t1 and t2 gives the cycle time and its
reciprocal is the frequency.
Example: a frequency of 10 Hz is required and would lead to
periodic duration of 100 ms. This 100 ms can be freely allocated
to t1 and t2, e.g. 50 ms:50 ms (isosceles triangle) or 99.9 ms:0.1
ms (right-angled triangle or sawtooth).
3.11.7 Rectangular function
The following parameters can be configured for a rectangular wave function. Following applies:
•
There is no preselection to which of both, source mode and sink mode, the function is applied to; the settings
decide whether it is “source mode only”, “sink mode only” or a mixture of both
•
When applying the function to the voltage, the device can only switch to and work in sink mode if the external
voltage on the DC terminal is higher than the highest point ( amplitude) of the wave and the current set -
ting “I Sink” is not 0

t1 t2
A rectangular or square wave signal for use on the current
or voltage is generated. The intervals t1 and t2 define how
long the value of the amplitude (pulse) and how long the
value of the offset (pause) are effective.
The offset shifts the signal on the Y axis.
Intervals t1 and t2 can be used to define a duty cycle. The
sum of t1 and t2 gives the period and its reciprocal the
frequency.
Example: a rectangular wave signal of 25 Hz and a duty
cycle of 80% are required. The sum of t1 and t2, the period,
is 1/25 Hz = 40 ms. For a duty cycle of 80% the pulse time
(t1) is 40 ms*0.8 = 32 ms and the pause time (t2) is 8 ms
