DVM - Design Verification Module

Resistive Load

The Resistive Load subcircuit models a constant resistive load. This subcircuit is used by a number of built in test objectives. The resistance value can be set directly using the Res() function or can be automatically calculated from the output voltage using the IRes() function.

Parameters

The following table explains the parameters used in the Resistive Load.

Parameter Name	Default	Data Type	Range	Units	Parameter Description
LOAD_NAME	LOAD	String	n/a	n/a	Name of the DVM load. This name cannot contain spaces.
LOAD_RESISTANCE	2.00667	Real	Min: 0	Ω	Sets the load resistance of the load.

Testplan Entry

To set any managed DVM load to a Resistive Load subcircuit, place a Res() or IRes() testplan entry in the Load column.

The Res() testplan entry sets the load resistance directly. The IRes() testplan entry calculates the load resistance from a given current and the nominal output voltage. The syntax for the two tesplan entries are explained in the table below.

Res(REF, LOAD_RESISTANCE)

IRes(REF, CURRENT)

Argument	Range	Description
REF	n/a	The actual reference designator of the DVM load or the more generic syntax of OUTPUT:n where n is an integer indicating a position in the list of managed DVM loads.
LOAD_RESISTANCE	min: 0	The current for the load. This can be a numeric value or a symbolic value, such as percentage of full load.
CURRENT	min: 0	The DC Current for the load. The LOAD_RESISTANCE parameter is calculated from the nominal output voltage and the provided CURRENT.
