The component represents a polynomial source. Within the dialog you can choose a voltage
or current source.
The function models polynomials of free order, specified by the polynomial coefficients
p0…pn . The meaning of the coefficients depends on the order of the polynomial.

Dialog Settings
� «Source Type»
In the list, select Voltage or Current Source.
v «Order»
Defines the order of the polynom. Please note, you cannot define a variable or an expression
in this case. Only a positive whole number is accepted.
«Control Quantity»
Define the control component (quantity). Quantity parameter type. The type accepts only
voltage and current of voltmeters, ammeters, or wattmeters (e.g. VM1.V, AM2.I). The values
cannot be assigned by a variable. Enter the quantity of a meter or use the pin to connect the
quantity.
«Coefficient»
Define the Polynomial coefficients. Common parameter type. Enter a numerical value, a variable,
or an expression in the text box.
� � «Spice Compatible»
If the box is checked, the spice compatible reference arrow system is applied to the source.
