Load from SPICE (Frequency Domain) Express VI

Owning Palette: Load/Save Signals Express VIs

Installed With: LabVIEW SignalExpress

Imports data from a SPICE, PSpice, or Multisim file.

SPICE is a general-purpose circuit simulation program for nonlinear DC, nonlinear transient, and linear AC analyses. PSpice is SPICE for Windows and is part of the OrCAD® product line by Cadence Design Systems Inc. Multisim is an integrated desktop design entry and simulation system for design engineers created by Electronics Workbench.

Dialog Box Options

Parameter	Description
Imported Signal	Displays the signal you imported from a SPICE, PSpice, or Multisim file.
File and Signal Selection	Contains the following options: Simulation file type—Specifies the type of file to import. Options include SPICE, PSpice, and Multisim. The default is SPICE. Import file path—Specifies the name and location of the file you want to import. You can specify an absolute or relative path to the file. If you specify an absolute path, this step saves the path with the project. If you specify a relative path and you do not save the project, this step assumes the path is relative to the My Documents folder. If you specify a relative path and you save the project, the path is relative to the location where you save the project. Signals in file—Lists the signals in the file and specifies which signal the Imported Signal graph displays. Import—Specifies whether to import the selected signal from the file you specify in Import file path. If you place a checkmark in one of the Import checkboxes, LabVIEW SignalExpress exports that signal to the Project View. You can then send that signal to another step or plot it on the Data View. Resampling Setup—Contains the following options: Interpolation mode—Specifies the interpolation method. Options include Coerce, Linear, or Spline. The default is Coerce. df—Specifies the df. The default is 1. Signal Type—Defines the type of frequency signal. Options include: Magnitude - linear, Magnitude - dB, Phase - degrees, or Phase - radians. Magnitude—Specifies the data type of the output signal as Linear or dB. This option is available only when the file you import contains complex signals that include real and imaginary components. Phase—Specifies the data type of the output signal as degrees or radians. This option is available only when the file you import contains complex signals that include real and imaginary components. Domain—Specifies the data type of the output signal. The default is Frequency Waveform.
