Hi Timos, Thanks for your response. Yes, I want to alternate the polarity from Positive to Negative at predefined time, at t= 1 ms. Can you please tell me what will be the syntax for this function ? I have tried using 1 for positve polarity and 0 for negative polarity which did not work. I used, if(time>=0.001,0,1) which did not change the polarity. Please let me know the correct syntax.
