Graphics editor for definition of control signals

Control signals are also graphically configured.

Graphical display of output signal in a diagram

The output signal can be graphically displayed in a number of diagrams. This allows a
fast check of signal characteristics. Zoom functions and the insertion of a reference trace
permit in-depth evaluation without an external analyzer being required.

4.2 Display

The display shows the current signal generator state and offers graphical elements for
direct operation. It is divided into three sections:

●

The frequency and level display with info line indicates the main output signal param-
eters and reports the current state with status, error and warning messages.
