Dialog Settings
«Value»
Defines the output value. Enter a numerical value, a variable, or an expression in the text box
or use the pin to connect a quantity.
� � «Use Pin»
If the box is checked, the value is defined by the quantity connected to the pin, otherwise the
value in the text box is used.
� «Sample Time»
Select «System» for simulator-defined variable sample time. Select «Value» to define a numerical
value, a variable, or an expression in the text box or use the pin to connect a quantity.
Please note: The sample time must be a positive value.
� � «Use Pin»
If the box is checked, the sample time is defined by the quantity connected to the pin, otherwise
the value in the text box is used.
AC Parameters
� «Phase & Magnitude»
The Phase/Magnitude representation is selected. Common parameter types. Enter a numerical
value, a variable, or an expression in the text box. See also “AC Simulation Models” on
page 401.
� «Angular Dimension»
In the list, select radians or degrees for the angular dimension of the phase.
� «Real & Imaginary»
The Real/Imaginary representation is selected. Common parameter type. Enter a numerical
value, a variable, or an expression in the text box.
