Swept AC Voltage Source: ACVSS



This signal source is superseded and should be replaced with one of the following: AC_V for voltage sources, AC_I for current sources, or PORT_SRC for ports, with the Signal parameter set to this signal type.

The period for tone 1 sources is the inverse of the specified simulation frequency; see “Frequency Sweep Control” for details.


Name Description Unit Type Default
ID Voltage source ID Text V1
VStart DC voltage start Voltage 0 V
VStop DC voltage stop Voltage 5 V
VStep DC voltage step Voltage 1 V
Ang AC voltage angle Angle 0 Deg
Offset Waveform offset (does not affect DC) Voltage 0
DCVal DC value (Used for DC analysis) Voltage 0

Implementation Details

This element is identical to ACVS, except that it allow you to specify a voltage magnitude sweep.

NOTE: If a sinusoidal nonlinear source like this one has the parameter Ang=0 and is ideally terminated, then a nonlinear measurement (e.g. Pcomp or Vcomp) made at the fundamental output of that source will have an angle of -90deg. This discrepancy is consistent with the definition of the sine wave sources (as in SPICE), and the Fourier based harmonic component measurements. To avoid confusion, always measure or calculate the gain, and plot its angle.


This element does not have an assigned layout cell. You can assign artwork cells to any element. See “Assigning Artwork Cells to Layout of Schematic Elements” for details.
