How I can generate a continuous signal using a solver with fixed step size?

Hello people! In my simulation I must use a fixed step size (0.01 s) with the solver ode4 (Runge-Kutta). The input to my model is a constant block. I want that this block run each 0.2 second (I know how to do this) and I want a signal longer than the fixed step size..I mean I want a signal of the duration of 0.3 s, a continuous signal 0.3 s long. Is it possible? Thank you veru much, Fabrizio

Thank you Ryan for your answer and excuse me for the delay of this comment! Anyway I solved the problem in this way: I used an atomic subsystem linked with a rate transition block! in this way I can keep the step of the simulation at 0.01 s (it's a must) and inside the asub everithiing run at 0.2s! then the rate transition put the out of asub inside the main(because in that environment I have to manage the output)!

You need to let your tmax be 0.4 and solve then discard the data for 0.3<t<0.4
