«Input Signal»
Enter a quantity name used in your model sheet in the text box to define the input signal
(RLOAD.I, STEP.VAL, STATE.ST, VAR) or use the pin to connect a quantity. Please note: You
cannot use conservative nodes from circuits as input signal (N0002, GND).
� � «Use Pin»
If the box is checked, the input signal is defined by the quantity connected to the pin, otherwise
the value in the text box is used.

«Characteristic»
To describe the nonlinear relation, you must specify a name of an appropriate XY nonlinear
characteristic function. See also “Separate Component Characteristic” on page 297.
To define characteristic data you can do one of the following:
• «Use Pin»; the XY component, connected to the pin, provides the characteristic.
Within the Characteristic dialog:
• «Reference»; the name in the text box specifies an XY element placed on the sheet.
• «Lookup Table»
a. «File Reference»; the name in the text box specifies a variable which refers to a subsheet
port specifying a characteristic file.
b. «Lookup Table»; data pairs, defined in the table, are used for characteristic.
• � «File Name»; if you use an file, data pairs are displayed in the lookup table and used
for characteristic. You can modify the data when necessary.
� «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.
