DC Input Source

The DC input source is used for any test where a DC voltage is required. The DC Input Source can be managed, meaning specification values can be stored on the DVM Control Symbol and you can run the built-in testplans which require these symbolic values. This source includes probes which output graphs for the source voltage and current. DVM also automatically makes scalar measurements on managed input sources.

DC Source Parameters

The following table explains the relevant parameters.

Parameter Name Default Data Type Range Units Parameter Description
DC_VOLTAGE 5 Real   V DC voltage of input source
SOURCE_NAME SRC String n/a n/a Name of the DVM source. This name cannot contain spaces.
SOURCE_RESISTANCE 0.4 Real min:0 Sets the source resistance of the source.

Testplan Entry

To set any managed DVM source to a DC Source subcircuit, place a Dc() testplan entry in the Source column.

The Dc() testplan entry has the following syntax with the arguments explained in the table below.

Dc(REF, DC_VOLTAGE)
Argument Range Description
REF n/a The actual reference designator of the DVM source or the more generic syntax of OUTPUT:n where n is an integer indicating a position in the list of DVM sources
DC_VOLTAGE min: 0 The DC Voltage of the source..
