PyMeasure scientific package
############################

PyMeasure makes scientific measurements easy to set up and run.
The package contains a repository of instrument classes and a system for running experiment procedures, which provides graphical interfaces for graphing live data and managing queues of experiments.
Both parts of the package are independent, and when combined provide all the necessary requirements for advanced measurements with only limited coding.

PyMeasure is currently under active development, so please report any issues you experience to our `Issues page`_.

.. _Issues page: https://github.com/pymeasure/pymeasure/issues

PyMeasure runs on Python 3.8-3.12, and is tested with continuous-integration on Linux, macOS, and Windows.

Version 0.15.0 (2025-01-15)
===========================
Main items of this new release:

- pyproject.toml replaces setup.cfg
- 12 new instruments

Deprecated features
-------------------
- The FSL class imported from :code:`pymeasure/instruments/rohdeschwarz/fsl.py` is deprecated, the current version can be found in :code:`pymeasure/instruments/rohdeschwarz/fsseries.py`.

Instruments
-----------
- Add Agilent E5062A (@AlecVercruysse, #1146)
- Add Hewlett Packard 8753E VNA (@Sionwage, #1004)

- Add Philips PM6669 Universal Frequency Counter (@dirkjankrijnders, #570)
- Add Rohde&Schwarz FSSeries class for instruments such as FSL (previously stand-alone class), FSW and others (@jnnskls, #1156)
  Previously, the instrument class FSL could be imported from :code:`pymeasure/instruments/rohdeschwarz/fsl.py`, which can now be imported from :code:`pymeasure/instruments/rohdeschwarz/fsseries.py` alongside the base class FSSeries and FSW.
- Add Rigol dg822 waveform generator (@fthouin, #1159)

**Full Changelog**: https://github.com/pymeasure/pymeasure/compare/v0.14.0...v0.15.0


Version 0.14.0 (2024-05-22)
===========================
Main items of this new release:

- Add support for numpy 2.0
- Add support for python 3.12
- Improve academic quotability with an up to date Zenodo DOI and with citation information.
- Add default :code:`queue` method and a :code:`FileInputWidget`, allowing to more quickly get started with the PyMeasure user interface (:code:`ManagedWindow`).
- Add a :code:`SCPIMixin` base class for instruments instead of defining :code:`includeSCPI=True`
- Instrument manufacturer modules are no longer imported in the :code:`pymeasure/instruments/__init__.py` file.
  Previously, when importing a single instrument into a procedure, all instruments would be imported into memory through the manufacturer modules in :code:`pymeasure/instruments/__init__.py`.
  Removing manufacturer modules from that file lowers the memory footprint of pymeasure when importing an instrument.
  Instrument classes will need to be imported from the manufacturer module or explicitly from the instrument driver file.
  For example, :code:`from pymeasure.instruments import Extreme5000` will need to change to :code:`from pymeasure.instruments.extreme import Extreme5000` or :code:`from pymeasure.instruments.extreme.extreme5000 import Extreme5000`.
- 17 new instruments

Deprecated features
-------------------
- Remove :code:`TelnetAdapter`, as its library is deprecated (@BenediktBurger, #1045)
- Replaced :code:`directory_input` keyword-argument of :code:`ManagedWindowBase` by :code:`enable_file_input` (@CasperSchippers, #964)
- Make parameter :code:`includeSCPI` obligatory for all instruments, even those which use SCPI (@BenediktBurger, #1007)
- Setting `includeSCPI=True` is deprecated, inherit instead the :code:`SCPIMixin` class if the device supports SCPI commands.
- Replaced :code:`celcius` attribute of :code:`LakeShoreTemperatureChannel` by :code:`celsius` (@afuetterer, #1003)
- Replaced :code:`error` property of Keithley instruments by :code:`next_error`.
- Replaced :code:`measurement_time` property of Pendulum CNT-91 by :code:`gate_time`.
- Replaced :code:`sample_rate` keyword-argument of :code:`buffer_frequency_time_series` of Pendulum CNT-91 by :code:`gate_time`.
- Replaced MKS937B :code:`unit` to use :code:`instruments/mksinst/mks937b/Unit` instead of strings (@dkriegner, @BenediktBurger #1034)

**Full Changelog**: https://github.com/pymeasure/pymeasure/compare/v0.13.1...v0.14.0


Version 0.13.1 (2023-10-05)
===========================
New release to fix ineffective python version restriction in the project metadata (only affected Python<=3.7 environments installing via pip).

Version 0.13.0 (2023-09-23)
===========================
Main items of this new release:

- Dropped support for Python 3.7, added support for Python 3.11.
- Adds a test generator, which observes the communication with an actual device and writes protocol tests accordingly.
- 2 new instrument drivers have been added.

Deprecated features
-------------------
- Attocube ANC300: The :code:`stepu` and :code:`stepd` properties are deprecated, use the new :code:`move_raw` method instead. (@dkriegner, #938)

Instruments
-----------

**Full Changelog**: https://github.com/pymeasure/pymeasure/compare/v0.12.0...v0.13.0


Version 0.12.0 (2023-07-05)
===========================
Main items of this new release:

- A :code:`Channel` base class has been added for easier implementation of instruments with channels.
- 19 new instrument drivers have been added.
- Added tests for some commonalities across all instruments.
- We continue to clean up our API in preparation for a future version 1.0. Deprecations and subsequent removals are listed below.

Deprecated features
-------------------
- HP 34401A: :code:`voltage_ac`, :code:`current_dc`, :code:`current_ac`, :code:`resistance`, :code:`resistance_4w` properties, use :code:`function_` and :code:`reading` properties instead.
- Toptica IBeamSmart: :code:`channel1_enabled`, use :code:`ch_1.enabled` property instead (equivalent for channel2). Also :code:`laser_enabled` is deprecated in favor of :code:`emission` (@bmoneke, #819).
- TelnetAdapter: use :code:`VISAAdapter` instead. VISA supports TCPIP connections. Use the resource_name :code:`TCPIP[board]::<hostname>::<port>::SOCKET` to connect to a server (@Max-Herbold, #835).
- Attocube ANC300: :code:`host` argument, pass a resource string or adapter as :code:`Adapter` passed to :code:`Instrument`. Now communicates through the :code:`VISAAdapter` rather than deprecated :code:`TelnetAdapter`. The initializer now accepts :code:`name` as its second keyword argument so all previous initialization positional arguments (`axisnames`, `passwd`, `query_delay`) should be switched to keyword arguments.
- The property creators :code:`control`, :code:`measurement`, and :code:`setting` do not accept arbitrary keyword arguments anymore. Use the :code:`v_kwargs` parameter for arguments you want to pass on to :code:`values` method, instead.
- The property creators :code:`control`, :code:`measurement`, and :code:`setting` do not accept `command_process` anymore. Use a dynamic property or a `Channel` instead, as appropriate (@bmoneke, #878).
- See also the next section.

New adapter and instrument mechanics
------------------------------------
- All instrument constructors are required to accept a :code:`name` argument.
- Changed: :code:`read_bytes` of all Adapters by default does not stop reading on a termination character, unless the new argument :code:`break_on_termchar` is set to `True`.
- Channel class added. :code:`Instrument.channels` and :code:`Instrument.ch_X` (:code:`X` is any channel name) are reserved attributes for channel mechanics.
- The parameters :code:`check_get_errors` and :code:`check_set_errors` enable calling methods of the same name. This enables more systematically dealing with instruments that acknowledge every "set" command.

- Adds Channel feature to instruments (@bmoneke, mcdo0486, #718, #761, #852, #931)
- Adds :code:`maxsplit` parameter to :code:`values` method (@bmoneke, #793)

**Full Changelog**: https://github.com/pymeasure/pymeasure/compare/v0.11.1...v0.12.0

Version 0.11.1 (2022-12-31)
===========================
Adapter and instrument mechanics
--------------------------------
- Fix broken `PrologixAdapter.gpib`. Due to a bug in `VISAAdapter`, you could not get a second adapter with that connection (#765).

**Full Changelog**: https://github.com/pymeasure/pymeasure/compare/v0.11.0...v0.11.1

Dependency updates
------------------
- Required version of `PyQtGraph <https://www.pyqtgraph.org/>`__ is increased from :code:`pyqtgraph >= 0.9.10` to :code:`pyqtgraph >= 0.12` to support new PyMeasure display widgets.

GUI
---
- Added `ManagedDockWindow <https://pymeasure.readthedocs.io/en/latest/tutorial/graphical.html#using-the-manageddockwindow>`__ to allow multiple dockable plots (@mcdo0486, @CasperSchippers, #722)

- New sequencer architecture (@msmttchr, @CasperSchippers, @mcdo0486, #518)
- Added "Save Dock Layout" functionality to DockWidget context menu. (@mcdo0486, #762)

Version 0.11.0 (2022-11-19)
===========================
Main items of this new release:

- 11 new instrument drivers have been added
- A method for testing instrument communication **without** hardware present has been added, see `the documentation <https://pymeasure.readthedocs.io/en/latest/dev/adding_instruments.html#protocol-tests>`__.
- The separation between :code:`Instrument` and :code:`Adapter` has been improved to make future modifications easier. Adapters now focus on the hardware communication, and the communication *protocol* should be defined in the Instruments. Details in a section below.
- The GUI is now compatible with Qt6.
- We have started to clean up our API in preparation for a future version 1.0. There will be deprecations and subsequent removals, which will be prominently listed in the changelog.

Deprecated features
-------------------
In preparation for a stable 1.0 release and a more consistent API, we have now started formally deprecating some features.
You should get warnings if those features are used.

- Adapter methods :code:`ask`, :code:`values`, :code:`binary_values`, use :code:`Instrument` methods of the same name instead.
- Adapter parameter :code:`preprocess_reply`, override :code:`Instrument.read` instead.
- :code:`Adapter.query_delay` in favor of :code:`Instrument.wait_for()`.
- Keithley 2260B: :code:`enabled` property, use :code:`output_enabled` instead.

New adapter and instrument mechanics
------------------------------------
- Nothing should have changed for users, this section is mainly interesting for instrument implementors.
- Documentation in 'Advanced communication protocols' in 'Adding instruments'.
- Adapter logs written and read messages.
- Particular adapters (`VISAAdapter` etc.) implement the actual communication.
- :code:`Instrument.control` getter calls :code:`Instrument.values`.
- :code:`Instrument.values` calls :code:`Instrument.ask`, which calls :code:`Instrument.write`, :code:`wait_for`, and :code:`read`.
- All protocol quirks of an instrument should be implemented overriding :code:`Instrument.write` and :code:`read`.
- :code:`Instrument.wait_until_read` implements waiting between writing and reading.
- reading/writing binary values is in the :code:`Adapter` class itself.
- :code:`PrologixAdapter` is now based on :code:`VISAAdapter`.
- :code:`SerialAdapter` improved to be more similar to :code:`VISAAdapter`: :code:`read`/:code:`write` use strings, :code:`read/write_bytes` bytes. - Support for termination characters added.
