Ivi.DCPwr.Interop

IviDCPwr class-compliant root interface

Opens the I/O session to the instrument. Driver methods and properties that access the instrument are only accessible after Initialize is called. Initialize optionally performs a Reset and queries the instrument to validate the instrument model.

An IVI logical name or an instrument specific string that identifies the address of the instrument, such as a VISA resource descriptor string. Specifies whether to verify the ID of the instrument. Specifies whether to reset the instrument. The user can use the OptionsString parameter to specify the initial values of certain IVI inherent attributes for the session. The format of an assignment in the OptionsString parameter is "Name=Value", where Name is one of: RangeCheck, QuerytInstrStatus, Cache, Simulate, RecordCoercions, InterchangeCheck, or DriverSetup. Value is either true or false except for DriverSetup. If the Options String parameter contains an assignment for the Driver Setup attribute, the Initialize function assumes that everything following "DriverSetup=" is part of the assignment.

Closes the I/O session to the instrument. Driver methods and properties that access the instrument are not accessible after Close is called.

IviDCPwr class-compliant IIviDCPwrOutput interface

method Configure Current Limit specifies the output current limit value and the behavior of the power supply when the output current is greater than or equal to that value.

Specifies the behavior of the power supply when the output current is greater than or equal to the value of the Limit parameter. The driver uses this value to set the Current Limit Behavior attribute. See the attribute description for more details. Specifies the power supply's output current limit. The driver uses this value to set the Current Limit attribute.

method Configure Range specifies the output's range, either current or voltage.

The kind of range to be configured, either Current or Voltage. The range in which the power supply operates. This value is coerced to the closest value the instrument supports that is greater than or equal to the value specified.

method Configure OVP specifies the over-voltage limit and the behavior of the power supply when the output voltage is greater than or equal to the limit.

Specifies the behavior of the power supply when the ouptut voltage is greater than or equal to the value of the Limit parameter. This value sets the OVP Enabled property. Specifies the power supply's over-voltage protection limit. This value sets the OVP Limit property

method Measure takes a measurement on the output signal and returns the measured value.

The type of measurement to take, either Current or Volatge The measured value.

method Query Current Limit Max returns the maximum programmable current limit that the power supply accepts for a particular voltage level on an output.

The voltage level for which to determine the maximum programmable current limit. Returns the maximum programmable current limit for the specified voltage level.

method Query State returns whether the power supply is in a particular output state.

The output state for which to query. Allowed values are those defined in the IviDCPwrOutputStateEnum enumeration. Returns True if the power supply is currently in the state specified with the OutputState parameter, and False if it is not.

method Query Voltage Level Max returns the maximum programmable voltage level that the power supply accepts for a particular current limit on an output.

The current limit for which to determine the maximum programmable voltage level. Returns the maximum programmable voltage level for the specified current limit.

method Reset Output Protection resets the power supply's output protection after an over-voltage or over-current condition occurs.

property Enabled specifies whether the signal the power supply produces appears at the output connector.

property Source specifies the trigger source.

property Triggered Current Limit specifies the value to which the power supply sets the current limit after a trigger event occurs.

property Triggerd Voltage Level specifies the value to which the power supply sets the voltage level after a trigger event occurs.

property Voltage Level specifies the voltage level the DC power supply attempts to generate. The units are Volts.

propety Current Limit specifies the output current limit. The units are Amps.

property Current Limit Behavior specifies the behavior of the power supply when the output current is equal to or greater than the value of the Current Limit property.

property OVP Limit specifies the voltage the power supply allows. The units are Volts.

property OVP Enabled specifies whether the power supply provides over-voltage protection. If this property is set to True, the power supply disables the output when the output voltage is greater than or equal to the OVP Limit.

IviDCPwr class-compliant IIviDCPwrTrigger interface

method Abort returns the power supply to the ignore triggers state if the power supply is currently waiting for a trigger to change the output signal. If the power supply is not waiting for a trigger, this method does nothing.

method Initiate causes the power supply to wait for a trigger if the power supply is not currently waiting for a trigger. If the power supply is already waiting for a trigger, this method does nothing

method Send Software Trigger supplies a trigger signal when the trigger source is set to Software Trigger
