In Parameter stepping mode, TINA steps the associated component values a given number of times
through a given range and runs the selected analysis for each value. This results in the calculation and
plotting of a set of curves illustrating the sensitivity of the circuit to changes in the associated
parameters.
Parameter Stepping is controlled by four parameters: Start value, End value, Number of cases, and
Sweep type (Linear, Logarithmic or List).
The stepped component value parameters can be any numerical parameters of the TINA components–
e.g., the resistance of resistors, the setting of a potentiometer, or parameters on transistor data sheets.
To set up parameter stepping for a component, click on the Analysis.Control Object menu item, or
click on the Select Control Object speed button.
A cursor that looks like a resistor will appear in the schematic editor window, waiting for you to
identify the component for which you wish to assign a stepped parameter. Point at the desired
component, right click, and all of its associated parameters will be displayed in the dialog window.
Should the desired parameter belong to a catalog component or be an excitation attribute, you must first
select the semiconductor or waveform type so that you can access the appropriate data sheet.
In the case of a resistor, for example, the following dialog window will appear:
