DC Input Source
The DC input source is used for any test or simulation where a DC voltage is required. This source includes probes which output graphs for the source voltage and current.
When used in DVM, 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. 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 | Ω | Sets the source resistance of the source. |
DVM 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.. |
Converting between DVM and Power Supply Sources
To change a Power Supply source to a DVM source, right click the symbol to bring up the context menu, and select the menu option: Upgrade to DVM Source/Load
To change a DVM source to a Power Supply source, right click the symbol to bring up the context menu, and select the menu option: Downgrade to SIMetrix/SIMPLIS Source/Load
