QCoDeS/Qcodes: v0.38.0

Description

QCoDeS 0.38.0 (2023-04-25) Breaking Changes:

  • The modules qcodes_loop.data, qcodes_loop.plots, qcodes_loop.actions, qcodes_loop.loops, qcodes_loop.measure, qcodes_loop.extensions.slack and qcodes_loop.utils.magic, qcodes_loop.utils.qt_helpers have been split out into a separate package qcodes_loop. The respective modules in QCoDeS do still exist as deprecated aliases to the new modules in qcodes_loop but will be removed in a future release. To use the aliases QCoDeS must be installed with the loop extra e.g. you should install pip install qcodes[loop]. If you make use of these modules we recommend updating imports to use qcodes_loop as soon as possible. See the readme <https://github.com/qcodes/qcodes_loop>_ of qcodes_loop for more information.

    The functions qcodes.utils.helpers.tprint qcodes.utils.helpers.wait_secs and qcodes.utils.helpers.foreground_qt_window have been removed. These helper functions are only used in qcodes_loop and were moved there. (#4971)

  • The default configuration of QCoDeS dataset GUID_components.GUID_type has changed from explicit_sample to random_sample. This means that QCoDeS GUIDs will no longer start with aaaaaaaa but with a random string. This significantly reduces the risk of duplicate GUIDs. This also means that that the ability to set a sample_id as part of the dataset GUID is disabled by default. With the default config its therefor an error to set GUID_components.sample to anything but the default value. The original behavior can be restored by setting GUID_components.GUID_type to explicit_sample in the config file but is not recommended. Users should make use of the sample_name attached to an experiment as an alternative. Note that if you have already created a local config you will need to update this for the changes to take effect. (#5031)
Improved:
  • The helper functions guids_from_dbs, guids_from_dir, and guids_from_list_str have been added to the documented dataset api at qcodes.dataset. (#4989)
Improved Drivers:
  • Fixed a bug in version parsing for Keysight 344XXA and Keysight E4980A which would result in incompatibility with packaging>21 under certain circumstances. (#5007)
  • Fixed a bug in interlock status querying for Keithley 3706A. Originally, not all potential responses from the system were accounted for when querying for interlock status. A dictionary is used to map the response from the system to a string describing the interlock status. When the system returns a response that was not accounted for, this resulted in a KeyError being raised. Now, this dictionary accounts for all potential responses from the system. (#5013)
  • Added support for AimTTi QL355TP power supply. Moved _numOutputChannels lookup table to the class body. (#5021)
  • Increased range on setpoint property of Lakeshore Model 335,336,372 to support degree Celsius (#5043)
  • Fix auto_sweep in Keysight PNA N52xx driver Fix units of polar sweeps in Keysight PNA N52xx driver (#5090)
New:
  • The QCoDeS Station Instrument and InstrumentModule classes gained a method get_component which allows the user to get a component by name. Allowing the user to go from the full name of a component to the component itself. (#5028)
New Drivers:
  • Add driver for Lakeshore Model 335 (#5043)
