0.6.0 - 2023-02-27

Changed

  • Refactor package structure by @bleykauf in #277

Removed

  • We are no longer providing a Linux executable since it cannot be built using CI (see #263) and most users run Windows. We recommand installing linien-gui using pip (see the updated readme). If you encounter any problems, please open an issue.

0.5.3.post2 - 2023-02-24

Fixed

  • Fix file extension in linien_start_server.sh, see #291. Thank you, @doronbehar!

0.5.3 - 2023-04-12

Fixed

  • Fix bug preventing proper starting and stopping of linien-server

0.5.2 - 2023-04-05

Added

  • Better keyboard controls for spinboxes

0.5.1 - 2023-02-17

Added

  • Re-enable sweep for fast mode.

0.5.0.post1 - 2022-01-24

Added

  • Better sweep controls make it easier to adjust the sweep range and allow to stop the sweep altogether.
  • A new, faster PID-only mode allows for a higher control bandwidth by skipping modulation/demodulation steps (useful for offset locks).
  • Added Welch's method to the measurement of the error signals power spectral density (PSD).

Changed

  • The parameters that deal with the sweep / ramp have been renamed:
    • "center" is now "sweep_center"
    • "ramp_amplitude", "ramp_speed" and * * "autolock_initial_ramp_amplitude" are now "sweep_amplitude" and * "sweep_speed" and "autolock_initial_sweep_amplitude", respectively There is a new boolean parameter "sweep_pause".

0.4.3 - 2021-06-22

Added

  • Disabled LED blinking as it causes additional noise (thanks to Yao-Chin!)
  • DC spectroscopy signal is displayed (thanks to aisichenko for the idea!)
  • lpsd is now used for psd measurements (samples psd on a log scale)

Fixed

  • various bug fixes especially in the autolock component

0.4.2 - 2021-03-14

Removed

  • Removed "Check lock" and "Watch lock" features as they caused problems with the new autolock algorithms as well as with noise analysis. These features are planned to be reimplemented in a future release (and in a more sophisticated way). If you rely on these features, consider using Linien version 0.3.2 until then.

0.4.1 - 2021-03-10

Fixed

  • fix a bug in the server package that lead to an incomplete install

[0.4.0] - 2021-03-10

Added

  • Implemented new autolock algorithms that are faster and work with high jitter
  • For noise analysis, PSD of the error signal may be recorded
  • Plot window of the main window may be zoomed / panned by clicking and dragging / using the mouse wheel
  • Parameters are not only backed up on the client side but also on the server. When client connects to a server with parameter mismatch, the user may decide whether to keep local or remote parameters

0.3.2 - 2021-01-06

Changed

  • improved documentation

Fixed

  • Mark incompatibility with rpyc==5.0.0

0.3.1 - 2020-12-30

Fixed

  • derivative of PID should work now as expected

0.3.0 - 2020-12-23

Added

  • IQ demodulation (simultaneous orthogonal demodulation) allows for determination of the spectroscopy signal strength. This makes one-shot optimization of the demodulation phase possible
  • ANALOG_OUTs can be set using python client or GUI
  • Device editing is now possible, leaving device's parameters untouched
  • Extra package for python client: pip install linien-python-client installs a headless version of the linien client that allows to control your lock in an environment that doesn't provide GUI libraries
  • Digital GPIO outputs are now accessible using python client
  • Keyboard shortcuts for zoom and pan: Use ← / → / + / -

Changed

  • Improved optimization algorithm: Automatic optimization of the slope of a line is now more robust and converges faster
  • More accurate autolock: Autolock reliability was improved

Fixed

  • Bug fixes and performance improvements
