class TemperatureController[source]#

Bases: Device

Methods

add_device

Manually add a specific device.

allow_only_dummy_devices

connect

connect_device

This function should be overridden by device implementations only, and is not intended to be used directly.

connect_dummy

Connect an instance of the device's dummy implementation

disable

enable

get_base_classes

Return a flat dictionary of all base classes below this class :param recurse: If True, recursively search for base classes :return: dict of {class name: class}

get_device_name

get_device_type_name

get_status

Query the status of the device and return a string describing errors.

get_temperature_C

is_connected

Query whether the device is (still) connected

is_enabled

list_devices

Get a list of all devices for this type.

set_temperature_C

wait_for_temperature_C

Wait until the device temperature reaches the target temperature

classmethod add_device(connect_info)#

Manually add a specific device. The device will show up when list_devices() is called for the device type. Call this from the device class implementation, e.g. use ModelXYZ9000.add_device(‘GPIB:1234:5678’) to add a specific device with a fixed GPIB address. This is useful when automatic discovery is undesired/impossible, either because it is not implemented or it disturbs other devices which can’t handle a identification request. :param cls: The device implementation class :param connect_info: A string argument that is passed to the connect() method of the device implementation, when the device is being connected.

classmethod connect(device_type_name: str, device_name: str | None, **kwargs) Device#
Parameters:
  • device_type_name – The name of the device class

  • device_name – The name of the device class

abstractmethod classmethod connect_device(device_name: str) Device#

This function should be overridden by device implementations only, and is not intended to be used directly. Instead, use list_devices() to get a list of devices, and pass the selected device type and name to connect() :param device_name: The name of the device class

classmethod connect_dummy(**kwargs) Device#

Connect an instance of the device’s dummy implementation

classmethod get_base_classes(recurse=True) dict[str, type[Device]]#

Return a flat dictionary of all base classes below this class :param recurse: If True, recursively search for base classes :return: dict of {class name: class}

classmethod get_device_name() str#
Returns:

The specific type name of the device, e.g., SR830 or Keithly2600

classmethod get_device_type_name() str[source]#
Returns:

The general type name of the device, e.g., Lock-In Amplifier or Voltmeter

get_status() str#

Query the status of the device and return a string describing errors. If everything is ok, empty string must be returned :return: String of device status

abstractmethod is_connected() bool#

Query whether the device is (still) connected

classmethod list_devices() list[tuple[str, str]]#

Get a list of all devices for this type. The list made up of: - Manually added devices - Available devices (those returned by _enumerate_devices) - A dummy device (if a dummy implementation exists) - List of all devices of child classes

Returns:

list of available devices

wait_for_temperature_C(target_temperature_C, timeout_s=None, sleep_interval=1, n_digits=0, log_interval=60) float[source]#

Wait until the device temperature reaches the target temperature

Blocks until the device temperature equals the target temperature (both rounded to the specified number of digits).

Parameters:
  • target_temperature_C – Target temperature in °C. Note: the controller must already be set to this temperature

  • timeout_s – Maximum number of seconds to wait. None for no timeout. If temperatures are not equal within timeout, raises RuntimeError

  • sleep_interval – Seconds to sleep between temperature checks

  • n_digits – Number of digits to round both temperatures before comparing

  • log_interval – Minimum seconds between log messages

Returns:

Number of seconds required to reach target temperature

Raises:

RuntimeError – If target temperature not reached within timeout period
