Enums¶

Enums used in NI-DCPower

ApertureTimeUnits¶

class nidcpower.ApertureTimeUnits[source]¶

SECONDS¶: Specifies aperture time in seconds.

POWER_LINE_CYCLES¶: Specifies aperture time in power line cycles (PLCs).

AutoZero¶

class nidcpower.AutoZero[source]¶

ComplianceLimitSymmetry¶

class nidcpower.ComplianceLimitSymmetry[source]¶

SYMMETRIC¶: Compliance limits are specified symmetrically about 0.

ASYMMETRIC¶: Compliance limits can be specified asymmetrically with respect to 0.

DCNoiseRejection¶

class nidcpower.DCNoiseRejection[source]¶

ON_MEASURE_TRIGGER¶: Acquires a measurement when a Measure trigger is received.

MeasurementTypes¶

class nidcpower.MeasurementTypes[source]¶

CURRENT¶: The device measures current.

VOLTAGE¶: The device measures voltage.

OutputCapacitance¶

class nidcpower.OutputCapacitance[source]¶

LOW¶: Output Capacitance is low.

HIGH¶: Output Capacitance is high.

OutputFunction¶

class nidcpower.OutputFunction[source]¶

DC_VOLTAGE¶: Sets the output method to DC voltage.

DC_CURRENT¶: Sets the output method to DC current.

PULSE_VOLTAGE¶: Sets the output method to pulse voltage.

PULSE_CURRENT¶: Sets the output method to pulse current.

OutputStates¶

class nidcpower.OutputStates[source]¶

VOLTAGE¶: The device maintains a constant voltage by adjusting the current

CURRENT¶: The device maintains a constant current by adjusting the voltage.

Polarity¶

class nidcpower.Polarity[source]¶

HIGH¶: A high pulse occurs when the event is generated. The exported signal is low level both before and after the event is generated.

LOW¶: A low pulse occurs when the event is generated. The exported signal is high level both before and after the event is generated.

PowerSource¶

class nidcpower.PowerSource[source]¶

INTERNAL¶: Uses the PXI chassis power source.

AUXILIARY¶: Uses the auxiliary power source connected to the device.

AUTOMATIC¶: Uses the auxiliary power source if it is available; otherwise uses the PXI chassis power source.

PowerSourceInUse¶

class nidcpower.PowerSourceInUse[source]¶

INTERNAL¶: Uses the PXI chassis power source.

AUXILIARY¶: Uses the auxiliary power source connected to the device. Only the NI PXI-4110, NI PXIe-4112, NI PXIe-4113, and NI PXI-4130 support this value. This is the only supported value for the NI PXIe-4112 and NI PXIe-4113.
