Changelog

This list oulines major new features and bug fixes between releases of the ImAFM™ suite. Each release typically also includes additional minor bugfixes and smaller new features.

Version 4.0.1

Release date: 2019-09-09

Due to changes in the hardware bootup sequence the following commands must be run from the built-in Python shell once for every MLA (if it was shipped with an older version).

from mlaapi import setup
setup.upload_bootware(mla.hardware.ip_address)

Additionally, if the IP-address has been changed from the default 192.168.42.50 you must also run

setup.set_ip_address(mla.hardware.ip_address, mla.hardware.ip_address)

Improvements

  • Various improvements to Frequency sweep: voltage kept at zero after sweep, individual curves can be shown / hidden from toolbar.

Bugfixes

  • Removed transients appearing during startup.
  • Fix bug in ADFS force volume export.
  • Various bugfixes in cantilever calibrator: allow <1kHz range, allow user to re-zoom while acquiring data.

Version 4.0

Release date: 2019-07-24

We have made a major transition of the software under the hood. It is now based on Python 3 instead of Python 2, and is therefor more future proof. With this upgrade we are simulatenously dropping support for MLA gen2, there will be no parallell releases of gen2-software. Data obtained with MLA gen2 hardware can however still be opened and analysed in this and future versions to make use of the latest analysis techniques.

New features

  • Support for MLA gen3.1 (serial numbers >= 3100).
  • Stream Recorder saves DC values of all four inputs with lockin data.
  • Verbose flag added (-v) to show more warnings and error messages

Improvements

  • Model fit parameter maps speed up.
  • New entry-point to software with more obvious name “start_afm.py”

Bugfixes

  • Fix in Stream Recorder with low df.

Version 2.8 / 3.2

Release date: 2019-02-22

New features

  • “Moving surface model” analysis plugin included by default.

Improvements

  • DMT_EXP model renamed DMT_ExpDamp to clarify exponential damping.

Bugfix

  • Fixed set new calibration from Session overview.

Version 2.4.1

Release date: 2016-10-04

New features

  • Frequency sweep: reverse sweep direction.
  • Manual setup panel for setting up the lockin.
  • New ScanData file format version (9) keeping track of scan type (ImAFM, ImEFM etc).
  • Model fit parameter maps additionally stored as ASCII files.
  • Lifted motion displayed together with free motion in show meta data browser.

Bugfixes

  • ScanData: fixed export to ascii and sampling frequency was not correct when using drive constructor.
  • Easier to use binary Gwyddion loader for “.imp”-files. Does not require any special version of or python Gwyddion for windows. Note: requires installation of Visual Studio 2015 redistributables from Microsoft.

Version 2.4

Release date: 2016-06-30

New features

  • New MLA firmware: MLA can measure DC-component at all inputs simultaneously.
  • Script to record ramps / approach curves using DC signal.
  • Support fo NT-MDT triggers.
  • New format for storing calibration in ScanData files.

Bugfixes

  • Improved interpretation of EOL and EOF signals from AFM. Trace/retrace and left/right flipping is automatically syncronized after EOF trigger. First and last scan line of images now stored correctly.
  • Fix model fit force curves not appearing when using area tool.

Version 2.3

Release date: 2016-04-06

New features

  • Measure lift.

  • When saving an image directly from the GUI you will now get a dialog box where you can type the resolution. There is also a new option in the “Save as type” field named “Native resolution png”. With this option pure png files will be saved with the same resolution as the data. In addition, separate files with the colorbars will be generated. This could be practical if you want to assemble the figure yourself in for example powerpoint.

  • There is a hold-off time (default 1 ms) before a new trigger can be accepted to avoid bouncing.

  • Phase feedback using port OUT C. This is activated from the python shell with:

    mla.feedback.activate_phase()

    The full phase range of -pi to +pi corresponds to a voltage range of -1 V to +1 V. You can offset the voltage with mla.feedback.set_phase_offset(val), when val is -32768 to 32767.

    A more convenient way to adjust the offset may be to use mla.feedback.set_current_phase_to_value(V), where V is a voltage (-4 to +4). This will read the current phase value and adjust the offset of the phase feedback so that the resulting voltage on port OUT C is the specified value.

    Before you can do anything with the phase feedback, the normal feedback must be set up as usual with the “Setup” button in the “Scanner” or the “Advanced setup” perspectives. This phase feedback is to be considered experimental.

  • Gwyddion plug-in to open ScanData files. Instructions for how to install it in the folder C:Program FilesIMP Software SuiteExtToolsGwyddion

  • New icon in the start menu to start the software in Debug mode.

Bugfixes

  • Better handling of unusual values of amplitude and df.
