Hello Thar, attach an Abs (for absolute) block from the Math Operations library to the Sine Wave generator (Sources). In the Sine Wave block you can define the signal parameters (frequency, amplitude). 1 ms would be the simulation stop time.
Similarly, in MATLAB,
 t = 0:1e-5:1e-3;
 y = abs(0.2 * sin(2*pi*2e3*t));
 plot(t,y)
