How to set the rise time in a transient analysis? For example, in the circuit given below, when I perform transient analysis I want to set the rise time of the supply voltage curve of the power supply unit to be 50ms but TINA just provides start and end time of the transient analysis. I had to try different end time values such that the rise time was 50ms as shown in figure 3. Is there any way to manually set the rise time?
