DigitalSourceDCCurrentConfigureVoltageLimits Method
Specifies the voltage limit high, or high clamp voltage (Vch), and voltage limit low, or low clamp voltage (Vcl) for the pin set when forcing current.
Namespace: NationalInstruments.ModularInstruments.NIDigital
Assembly: NationalInstruments.ModularInstruments.NIDigital.Fx40 (in NationalInstruments.ModularInstruments.NIDigital.Fx40.dll) Version: 2021
Syntax
public void ConfigureVoltageLimits( double voltageLimitLow, double voltageLimitHigh )
Public Sub ConfigureVoltageLimits ( voltageLimitLow As Double, voltageLimitHigh As Double )
Parameters
- voltageLimitLow
- Type: SystemDouble
The nominal voltage at the pin at which the low side voltage clamp activates when the PPMU forces current to the DUT. - voltageLimitHigh
- Type: SystemDouble
The nominal voltage at the pin at which the high side voltage clamp activates when the PPMU forces current to the DUT.
Exceptions
| Exception | Condition |
|---|---|
| SelectorNameException | An instance of DigitalPinSet references a pin or pin group name not loaded in the pin map. |
| OutOfRangeException |

Remarks
The upper and lower voltage limits apply when you set the SelectedFunction of the pin set to
Ppmu.
When forcing current by setting the PPMU OutputFunction to DCCurrent, the voltage is clamped to the specified voltage limits. Select the smallest voltage limits appropriate for the DUT.
If the voltage required by the DUT exceeds the specified voltage limits, the current output may not meet the specified current level. Choose larger voltage limits as needed and appropriate for the DUT.
Changing this property does not take affect until you call Source. You can call Source to commit your changes even if the PPMU is already sourcing.
