Compute impedance versus frequency of Impedance Measurement blocks in model
MATLAB® command prompt: Enter
sys is a string scalar or character vector that is the name of a
powergui block: Under Tools, click Impedance Measurement.
Model— Name of model
Name of the model under analysis. Enter the name of a model to analyze, then click Update.
Update— Display or update
Display or update the impedance versus frequency measurement for the model specified in the Model parameter and, if Save data to workspace is selected, save the data to your workspace.
Impedance Measurement blocks— Lists Impedance Measurement blocks
Lists the Impedance Measurement blocks in the model. Select the blocks for which you want to obtain the frequency response. Press Ctrl to select several impedances to display on the same plot.
Impedance Axis— Choose logarithmic or linear scale
Choose logarithmic or linear scale for the vertical impedance scale.
Frequency Axis— Choose logarithmic or linear scale
Choose logarithmic or linear scale for the horizontal frequency scales.
Range— Frequency vector
Frequency vector, in hertz. You can specify any valid MATLAB expression that defines a vector of frequencies; for example,
Save data to workspace— Save data in variable
Select to save the data in a variable in the workspace. The name of the variable is defined by the Variable name parameter. The complex impedances are saved in an array with the corresponding frequencies. Frequency is saved in column 1 and impedances are saved in the next columns.
Variable name— Name of variable
Name of the variable to save in the workspace.
To enable this parameter, select Save data to workspace.
