.STEP and .MEAS in LTspice .AC Simulations

Jul 15 2026

Topics include:

  • Parameterizing a component value and using .param directive
  • Sweeping values with a .step directive using a list or a range
  • Selecting and annotating steps in the waveform viewer
  • Automating measurements with .meas statements
  • Placing multiple directives in one text box
  • Reading results in the SPICE output log
  • Changing the AC measurement complex format from dB to polar
