    I am using LT-SPICE and is having trouble of finding a way to do a frequency sweeping. Can anyone help?

    If i not mistaken, the option to do that is the AC analysis (in simulate - > edit simulation cmd). For example, if you select DECADE sweep, 10 points per decade, start frequency 1m, end frequency 1Meg, the program would sweep the frequency from 1 millihertz to 1 megahertz.
    Note: you need to assign the value "AC 1." (without quotes) to the voltage source you want to use for the sweep.
    I think it's even on the help file.

    Save this file in your SwCADIII directory, then start LTSpice and open the file.
