    hi everybody

     did anyone know how to make a fixed step time for a transient analysis.

    thanks

    Use the strobeperiod option on the tran analysis. Note that internally the simulator will still take whatever timesteps needed in order to accurately follow the circuit behaviour, and will also solve at the specified strobeperiod. It only outputs the timesteps at the strobeperiod.

    This makes it a very effective way of generating good data for performing an FFT on afterwards; it's regularly spaced, without interpolation errors which you'd normally get by sampling the data.

    Regards,

    Andrew
