using 3 sine wave block in simulink

i have used multiport switch with 3 data ports as sine waves with amplitude 1,2,3 respectively and a constant block with value 1,in scope i get only one sine wave ,how to get three sinewaves in it ,please help,my stop time is 30s

Hey, Multiport switch let you choose one of the inputs (with its first input). If you put a constant with the value 1 in the first input, the output of the multiport switch must be your first signalwave (the second input of the block).

So it's normal that you see only one sine wave on the scope.

To see the 3 sine wave, use a MUX instead of a Multiport Switch.
