A triangular wave signal for output current (only effective 
in current limiting) or output voltage is generated. The 
positive and negative slope times can be set indepen-
dently.
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 (isos-
celes triangle) or 99.9 ms:0.1 ms (right-angled triangle 
or sawtooth).
3.9.7  Rectangular function
The following parameters can be configured for a rectangular wave function:

A rectangular or square wave signal for output current 
(only effective in current limiting) or output 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 cycle time and its reciprocal 
is 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.
