Properties
| Name | Description |
|---|---|
| ActualPowerAllocation | Gets the power, in watts, the device is sourcing on each active channel if the PowerAllocationMode property is set to Automatic or Manual. |
| AdvancedSequencing | Gets the DCPowerOutputSourceAdvancedSequencing sub-object used to configure the advanced sequence properties of the source unit channel. |
| ComplianceLimitSymmetry | Specifies whether compliance limits for current generation and voltage generation for the device are applied symmetrically about 0 V and 0 A or asymmetrically with respect to 0 V and 0 A. |
| ConductionVoltageMode | Specifies whether the conduction voltage feature is enabled on the specified channel(s). |
| ConductionVoltageOffThreshold | Specifies the minimum voltage, in volts, at the input of the specified channel(s) below which the instrument stops sinking on the specified channel(s) when the conduction voltage feature is enabled. |
| ConductionVoltageOnThreshold | Specifies the required minimum voltage, in volts, at the input of the specified channel(s) before the instrument starts sinking on the specified channel(s) when the conduction voltage feature is enabled. |
| ConstantPower | Specifies the channel settings when the channel is configured for the ConstantPower. |
| ConstantResistance | Specifies the channel settings when the channel is configured for the ConstantResistance. |
| Current | Gets the DCPowerOutputSourceCurrent sub-object used to configure the current properties of the source unit channel. |
| CustomTransientResponse | Gets the DCPowerOutputSourceCustomTransientResponse sub-object used to configure the custom transient response of the source unit channel. |
| IsSequenceLoopCountFinite | Gets or sets whether a sequence should repeat indefinitely. |
| MergedChannels | Gets or sets the merge channel(s) to combine with a designated primary channel of an instrument in order to increase the maximum current you can source from the instrument. |
| Mode | Gets or sets whether to run a single output point or a sequence for the specified channel(s). |
| Output | Gets the DCPowerOutputSourceOutput sub-object used to configure the source unit channel output. |
| OutputCapacitance | Gets or sets whether to use a low or high capacitance on the output for the specified channel(s). |
| OutputCutoff | Gets the channel settings that define output cutoffs that, if exceeded, cause the output of the specified channel(s) to be disconnected. |
| OutputShorted | Specifies whether the input of the instrument simulates a short circuit. |
| OverrangingEnabled | Gets or sets whether NI-DCPower allows setting the voltage level, current level, voltage limit and current limit outside the device specification limits. |
| OvpEnabled | Gets or sets whether to enable or disable overvoltage protection (OVP). |
| OvpLimit | Determines the voltage limit, in volts, beyond which overvoltage protection (OVP) engages. Limit is specified as a positive value, but symmetric positive and negative limits are enforced simultaneously. For example, setting the OVP Limit to 65 will configure the OVP feature to trigger an OVP error if the output exceeds ±65 V. |
| PowerAllocationMode | Gets or sets whether the device sources the power its output configuration requires or a specific wattage you request; gets or sets whether NI-DCPower proactively checks that this sourcing power is within the maximum per-channel and overall sourcing power of the device. |
| PulseBiasDelay | Gets or sets the time, in seconds, when the device generates the PulseCompleteEvent. |
| PulseCurrent | Gets the channel settings when the channel is configured for the PulseCurrent. |
| PulseOffTime | Gets or sets the length, in seconds, of the off phase of a pulse. |
| PulseOnTime | Gets or sets the length, in seconds, of the on phase of a pulse. |
| PulseVoltage | Gets the channel settings when the channel is configured for the PulseVoltage. |
| RequestedPowerAllocation | Gets or sets the power, in watts, to request the device to source from each active channel. |
| SequenceLoopCount | Gets or sets the number of times a sequence is run after initiation. |
| SequenceStepDeltaTime | Gets or sets the amount of time, in seconds, between the start of two consecutive steps in a sequence. |
| SequenceStepDeltaTimeEnabled | Gets or sets whether the SequenceStepDeltaTime property is enabled (true) or disabled (false). |
| SourceDelay | Gets or sets the time, in seconds, when the device generates the SourceCompleteEvent. |
| TransientResponse | Gets or sets the transient response. |
| Voltage | Gets the DCPowerOutputSourceVoltage sub-object used to configure the Voltage properties of source unit channel. |
Methods
| Name | Description |
|---|---|
| QueryCurrentLimitMax(double) | Queries the maximum current limit on a channel if the channel is set to the specified voltageLevel. |
| QueryCurrentLimitMin(double) | Queries the minimum current limit on a channel if the channel is set to the specified voltageLevel. |
| QueryVoltageLevelMax(double) | Queries the maximum voltage level on a channel if you set the channel to the specified currentLimit. |
