When you run the simulation, the plot shows that the entities departing from the server
are spaced 1, 1.5, or 2 seconds apart. In this example, however, the simulation time is

probabilities.
Use a Step Function as Intergeneration Time
This example uses the Step block to generate entities at intervals of 1 or 2 seconds.
The Step block has these parameters:
