Port with Defined Frequency/1-Tone HB Source (2nd Tone): PORTF

Symbol

Summary

This signal source is superseded and should be replaced with one of the following: AC_V for voltage sources, AC_I for current sources, or PORT_SRC for ports, with the Signal parameter set to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

Parameters

Name Description Unit Type Default
P Port number   0
Z Termination impedance Resistance 50 ohm
Freq Frequency for tone 2 Frequency 1 GHz
Pwr Power in magnitude DB Power 0 dBm
*Ang Relative angle of the excitation Angle 0 Deg
PIN_ID Name identifier for pin Text  

Implementation Details

This is an active circuit termination that applies a load resistance specified by Z while supplying a power signal of magnitude Pwr and angle Ang and fixed frequency Freq. The port number P is set automatically. If PIN_ID is not empty, text displays on the pin when it is instantiated as a subcircuit.

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.

Layout

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.
