I have built a model in simulink. The model uses Bernoulli Binary Generator as its input. Now I have set the BBG block as below What I want to do: I would like to vary the data rate. In simulink, the sample time means the steps at which the block generates its output. Ex: if I set "Sample Time" = 0.01 and the duration of simulation is 1000, does that mean I am transferring 100 bits/second? Please explain.

So with the set up you have, the block outputs a new random binary number every 0.01s, and hence you are correct that you are generating 100 numbers per second, so 100 bits/second.
Some blocks, such as this one, also allow you to output a frame based signal. You are not doing this, but it is worth mentioning how that effects block execution. Lets say that you selected Frame based outputs and set a frame size of 100. Then the block would be executed every 0.01*100 = 1s. That is, you would get a new frame of 100 new bits every second. So you still have an overall bit rate of 100 bits/second.
