AC Voltage Source (Tone 2): ACVS2



This signal source is superseded and should be replaced with one of the following: AC_V for voltage sources, AC_I for current sources, or PORT_SRC for ports, with the Signal parameter set to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
Mag AC voltage magnitude Voltage 1 V
Ang AC voltage angle Angle 0 Deg
F AC frequency Frequency 1 GHz
Offset Waveform offset (does not affect DC) Voltage 0
DCVal DC value (Used for DC analysis) Voltage 0

Implementation Details

Produces a tone two alternating voltage with the frequency defined by F. The presence of one of these sources in the schematic automatically causes a two-tone analysis to be performed.

NOTE: If a sinusoidal nonlinear source like this one has the parameter Ang=0 and is ideally terminated, then a nonlinear measurement (for example, 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.
