The reason is, I would like to see the output of the system in time domain when the frequency changes. DC sweep can be used with any source that includes a DC offset variable. It increments the voltage or current of a selected source in predefined steps over a range of values. die Spannung einer Spannungsquelle) verändert wird. Contributors: LightningHawk. PWL 7. DC Sweep. LTspice offers an elegant solution for holding frequency constant and performing small signal analysis over a varying parameter. Einführung ins Simulations-Tool . There are two ways to examine a circuit in LTspice by changing the value for a particular parameter: you can either manually enter each value and then resimulate the circuit to view the response, or use the .step command to sweep across a range of values in a single simulation run.The .step command causes an analysis to be repeatedly performed whil The options for the simulation command appear. A nested sweep allows you to run two simultaneous sweeps to see how changes in two different DC sources will affect your circuit. In this article, we will explain in detail the monte carlo analysis(mc) method in LTspice.
