I'm trying to show on scope 2 signals - one is bit stream and the other one is the result of multiplication. Occured error is visible in attach.

Without scope3 plugged my model works properly and gives expected results.

Can you halp with that?

Hi, error in the model is due to the Product block. Its two inputs are of datatype 'int8' and 'double' and the output is of type 'double', but the wire expects a signal of type 'int8'.This causes an error. In this scenario, you can use Datatype Conversion Block or you can set the Output datatype of the product block.
