devices.keithley:Keithley2611A

Control interface for Keithley 2611A Source Measure Unit (SMU).

Usage

Source

devices.keithley:Keithley2611A(
    interface,
    **kwargs,
)

Provides methods to control and read data from the Keithley 2611A. It supports voltage and current sourcing and sensing in both 2-wire and 4-wire configurations.

Attributes

config_params: dict

Dictionary of configuration parameters and their corresponding commands

mode_int: dict

Mapping of mode strings to numeric values

mode_char: dict
Mapping of mode strings to character identifiers used in commands

Methods

Name Description
__init__() Initialize the Keithley 2611A instrument.
configure() Configure the Keithley 2611A to source and sense parameters.
getSense() Get the measured sense value.
getSource() Get the measured source value.
output() Control the output state of the instrument.
setSource() Set the source level.

__init__()

Initialize the Keithley 2611A instrument.

Usage

Source

__init__(
    interface,
    **kwargs,
)

Parameters

interface: str

VISA resource name or other interface identifier

**kwargs
Additional arguments passed to the parent VisaDevice class

Notes

Sets default termination characters and initializes the device. Reads the initial state including source mode, four-wire setting, and output state.

configure()

Configure the Keithley 2611A to source and sense parameters.

Usage

Source

configure(
    sourceMode=None,
    senseMode=None,
    fourWire=None,
    senseAutoRange=None,
    senseRange=None,
    sourceAutoRange=None,
    sourceRange=None,
    senseLimit=None,
    output=False,
    delayAuto=False,
    delay=None,
    reset=False,
)

Parameters

sourceMode: str = None

Parameter to source, “VOLT” or “CURR”.

senseMode: str = None

Parameter to measure, “VOLT” or “CURR”.

fourWire: bool = None

Four-wire (True) or two-wire (False) sensing.

senseAutoRange: bool = None

Automatically set the measurement range.

senseRange: float = None

Manual measurement range; the device selects the next inclusive range.

sourceAutoRange: bool = None

Automatically set the sourcing range.

sourceRange: float = None

Manual sourcing range; the device selects the next inclusive range.

senseLimit: float = None

Voltage or current limit for the sense circuit.

output: bool = False

Enable the output after configuration. Default is False.

delayAuto: bool = False

Automatically set the stabilization delay. Default is False.

delay: float or bool = None

Manual delay in seconds for output stabilization, or False to disable.

reset: bool = False
Reset the device before configuration. Default is False.

Notes

The output will be turned off during configuration. If sourceMode and senseMode are not provided, no configuration is done.

Examples

>>> instrument.configure(sourceMode="CURR", senseMode="VOLT",
                         fourWire=True, senseAutoRange=True,
                         sourceRange=0.001, output=True)

This configures the instrument to source current, measure voltage, use 4-wire sensing, automatically set the voltage measurement range, set the current sourcing range to include 1mA, and enable the output.

getSense()

Get the measured sense value.

Usage

Source

getSense()

Returns

float
The measured sense value (voltage or current depending on configured senseMode)

getSource()

Get the measured source value.

Usage

Source

getSource()

Returns

float
The measured source value (voltage or current depending on configured sourceMode)

output()

Control the output state of the instrument.

Usage

Source

output(state=False)

Parameters

state: bool = False
True to enable the output, False to disable

Returns

None

setSource()

Set the source level.

Usage

Source

setSource(current)

Parameters

current: float
The value to set the source to (can be voltage or current depending on configured sourceMode)

Returns

None
