A triangular wave signal for use on the current or voltage is generat-
ed. 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 recip-
rocal 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
Restrictions which apply particularly to this function:
•
There is no preselection to which of both, source mode and sink mode, the function is applied; the settings decide whether
it’s “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 setting “I (EL)” is not 0
The following parameters can be configured for a rectangular function:

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
