Rectangular pulse train

hi Ivar ,
i know this topic has been discussed on this forum but i still have a problem.
i want to generate a rectangular pulse train of pulse width = 28e-9 , frequency = 1 Hz
i used the rect function along with mod function to get an analytic function an1= rect1(mod(t[1/s],1e-9))
but when i plot this for time t = 0 to 1 sec i get zero magnitude , after solving i also found out that heat flux is zero throughout the time . I also tried 'make periodic' option but still not getting the plot.
As discussed earlier on some other thread , i made sure that the solver is selected as strict but still no luck .
i have to model 2 pulses each of 28 ns width in every second (t = 0 to 2 sec ) please help me with this .
