Types

type Driver

type Driver struct {
	ivi.Inherent
	// contains filtered or unexported fields
}

Driver provides the IVI driver for the Fluke 45 DMM.

func New

func New(inst ivi.Instrument, reset bool) (*Driver, error)

New creates a new Agilent3446x IVI Instrument.

func (*Driver) Abort

func (d *Driver) Abort() error

func (*Driver) ConfigureMeasurement

func (d *Driver) ConfigureMeasurement(
	msrFunc dmm.MeasurementFunction,
	autoRange dmm.AutoRange,
	rangeValue float64,
	resolution float64,
) error

func (*Driver) ConfigureTrigger

func (d *Driver) ConfigureTrigger(src dmm.TriggerSource, delay time.Duration) error

func (*Driver) FetchMeasurement

func (d *Driver) FetchMeasurement(maxTime time.Duration) (float64, error)

func (*Driver) InitiateMeasurement

func (d *Driver) InitiateMeasurement() error

func (*Driver) IsOverRange

func (d *Driver) IsOverRange(value float64) bool

func (*Driver) MeasurementFunction

func (d *Driver) MeasurementFunction() (dmm.MeasurementFunction, error)

MeasurementFunction returns the currently specified measurement function.

MeasurementFunction is the getter for the read-write IviDmmBase Attribute Function described in Section 4.2.1 of IVI-4.2: IviDmm Class Specification.

func (*Driver) QueryString

func (d *Driver) QueryString(cmd string) (string, error)

QueryString queries the DMM and returns a string.

func (*Driver) Range

func (d *Driver) Range() (dmm.AutoRange, float64, error)

Range returns the measurement range and whether auto range is enabled, disabled, or enabled for one measurement.

There is a dependency between the Range attribute and the Resolution Absolute attribute. The allowed values of Resolution Absolute attribute depend on the Range attribute. Typically, when the value of the Range attribute changes, the instrument settings that correspond to the Resolution Absolute attribute change as well. This is true regardless of how the change of measurement range occurs.

There are two possible ways that the measurement range can change. The application program can set the value of the Range attribute. Or, the instrument changes the measurement range because Range attribute is set to Auto Range On and the input signal changes. In both cases, the instrument resolution is likely to change.

The value of the MeasurementFunction attribute determines the units for this attribute as follows:

DC Volts = Volts AC Volts = Volts RMS DC Current = Amps AC Current = Amps 2-Wire Resistance = Ohms 4-Wire Resistance = Ohms AC Plus DC Volts = Volts AC Plus DC Current = Amps Frequency = Hertz Period = Seconds Temperature = Degrees Celsius

Range is the getter for the read-write IviDmmBase Attribute Range described in Section 4.2.2 of IVI-4.2: IviDmm Class Specification.

func (*Driver) ReadMeasurement

func (d *Driver) ReadMeasurement(maxTime time.Duration) (float64, error)

func (*Driver) ResolutionAbsolute

func (d *Driver) ResolutionAbsolute() (float64, error)

func (*Driver) SetMeasurementFunction

func (d *Driver) SetMeasurementFunction(msrFunc dmm.MeasurementFunction) error

SetMeasurementFunction specifies the measurement function.

SetMeasurementFunction is the setter for the read-write IviDmmBase Attribute Function described in Section 4.2.1 of IVI-4.2: IviDmm Class Specification.

func (*Driver) SetRange

func (d *Driver) SetRange(autoRange dmm.AutoRange, rangeValue float64) error

SetRange sets the range corresponding to the maximum input value based on the rest of hte instrument configuration (the same as the IVI.NET behavior). Setting this property sets AutoRange to Auto.Off If the property is set to a negative value and that negative value is valid for the current function (for instance DC Volts) the instrument will configure to measure that value.

SetRange is the setter for the read-write IviDmmBase Attribute Range described in Section 4.2.2 of IVI-4.2: IviDmm Class Specification.

func (*Driver) SetResolutionAbsolute

func (d *Driver) SetResolutionAbsolute(resolution float64) error

func (*Driver) SetTriggerDelay

func (d *Driver) SetTriggerDelay(autoDelay bool, delay float64) error

func (*Driver) SetTriggerSource

func (d *Driver) SetTriggerSource(src dmm.TriggerSource) error

func (*Driver) TriggerDelay

func (d *Driver) TriggerDelay() (bool, float64, error)

func (*Driver) TriggerSource

func (d *Driver) TriggerSource() (dmm.TriggerSource, error)
