WebThe first form is the traditional .tran SPICE command. Tstep is the plotting increment for the waveforms but is also used as an initial step-size guess. LTspice uses waveform compression, so this parameter is of little value and can be omitted or set to zero. Tstop is the duration of the simulation. WebOpen the schematic "01_sample-tran-lt1028.asc" and enter the following the ".measure" syntax in "SPICE Directive". .measure TRAN A MAX V(OUTPUT) This syntax means to measure the maximum voltage of V(OUTPUT) with the label "A".
