Special frequency probes serve to determine different subsystems to be computed and compared in the same diagrams . This gives you the ability to examine the closed and the open-loop behaviour with only one simulation. You can feed in the sinusoidal test signal and determine the starting point of a subsystem without cutting open the system. Standard block diagram elements SimApp has numerous basic blocks that are selected in the object palette by simply clicking on them. They are interconnected by wires to a complete system.
Most basic blocks have two alternative symbols .
The standard symbol shows the step response, the frequency plot or the graphical represantation of the transfer function. The mathematical notation of the transfer function serves as an alternative. Drawing capabilities SimApp has great similarites to a simple drawing program. In fact, for building block diagrams you need a lot of drawing facilities. Besides block diagram elements, you can draw lines, multisegment lines, polygons, rectangles, ellipses, write formated text and include pictures.
