Use these sources to create sinusoidal voltage and current waveforms.

You must specify a value for the VO, VA and FREQ parameters; The remaining parameters, if not specified, are assigned a default value.

# Parameters

Parameter | Description | Units | Default |
---|---|---|---|

Value | Frequency of the sinusoidal voltage or current. This value is used only if no value is specified for the parameter FREQ. | V or A | |

DC | DC Amplitude of the source used in operating point analysis. | V or A | 0 |

VO | DC offset voltage or current. Used to adjust the DC bias of the signal generator with respect to the negative terminal (usually ground). | V o A | |

VA | Peak amplitude of the sinusoid. | V o A | |

FREQ | Frequency of the sinusoidal voltage or current. The frequency can also be specified in the VALUE field of the symbol. If both FREQ and VALUE are specified, FREQ takes precedence. | Hz | |

TD | Delay time until the source voltage commences. Provides a phase shift of the output by delaying the start of the sine wave. | s | 0 |

THETA | Damping factor. Sets the rate at which the sinusoid decreases in amplitude. A positive value results in an exponentially decreasing amplitude; a negative value results in an exponentially increasing amplitude. A zero (0) value gives a constant amplitude sine wave. | 1/s | 0 |

PHASE | Phase shift of the sinusoid at time zero. | degrees | 0 |

ACMAG | AC Magnitude of small signal voltage or current. Set this if you plan to do a small signal AC analysis based on this source. | V or A | |

ACPHASE | AC Phase of small signal voltage or current. Set this if you plan to do a small signal AC analysis based on this source. If phase is omitted, a value of zero is assumed. | degrees | |

DISTOF1 | Set this if you plan to do a distortion analysis based on this source. Specify the amplitude and phase using space as separator. If phase is omitted, a value of zero is assumed. | ||

DISTOF2 | Set this if you plan to do a distortion analysis based on this source. Specify the amplitude and phase using space as separator. If phase is omitted, a value of zero is assumed. |
