General FG Description
6.9.2.1
Limitations
The function generator is not accessible, neither in manual nor remote control, if:
Master-slave mode has been activated and the unit was configured as slave.
Resistance mode (R/I adjustment, also called UIR) is active.
6.9.2.2
Resolution
Amplitudes generated by the arbitrary generator have an effective resolution of approx.
52428 steps. If the amplitude is very low and the time period long, the unit would generate
less steps and set multiple identical values after another, generating a staircase effect. It is
furthermore not possible to generate every possible combination of time and a varying
amplitude (slope).
The XY generator, which works in table mode, has an effective resolution of 3276 steps for
the set value range of 0-100% rated value.
6.9.3
Principle of Operation
In order to understand how the function generator works and how the value settings
interact, the following should be noted:
The unit operates, including in function generator mode, with the three set values U, I and P
at all times.
The selected function can be used on one of the values U or I, the other two are then
constants and have a limiting effect. That means, if, e.g. a voltage of 10 V is applied to the
DC input and a sine wave function should operate on the current with an amplitude of 20 A
and offset 20 A, then the function generator will create a sine wave progression of current
between 0 A (min) and 40 A (max), which will result in an input power between 0 W (min)
and 400 W (max).The input power, however, is limited to its set value. If this were 300 W
then, in this case, the current would be limited to 30 A and, if clamped to an oscilloscope, it
would be seen to be capped at 30 A and never achieve the target of 40 A.
6.9.4
Manual Operation
Via the touchscreen, one of the available FG functions
can be called up, configured and controlled. Selection
and configuration are only possible when the DC Input
is switched off.
How to select a function and adjust parameters
1.
While the DC Input is switched off tap the touch
area
on the main screen.
