Config Tab

The Config tab provides access to all major LabOne settings and is available on all HDAWG instruments.


  • define instrument connection parameters

  • browser session control

  • define UI appearance (grids, theme, etc.)

  • store and load instrument settings and UI settings

  • configure data recording


The Config tab serves as a control panel for all general LabOne settings and is opened by default on start-up. Whenever the tab is closed or an additional one of the same type is needed, clicking the following icon will open a new instance of the tab.

Control/Tool Option/Range Description


btn mnu mainconfig um

Provides access to software configuration.

The Config tab (see Figure 1) is divided into four sections to control connections, sessions, settings, user interface appearance and data recording.

The Connection section provides information about connection and server versions. Access from remote locations can be restricted with the connectivity setting.

The Session section provides the session number which is also displayed in the status bar. Clicking on Session Dialog opens the session dialog window (same as start up screen) that allows one to load different settings files as well as to connect to other instruments.

The Settings section allows one to load and save instrument and UI settings. The saved settings are later available in the session dialog.

The User Preferences section contains the settings that are continuously stored and automatically reloaded the next time an HDAWG instrument is used from the same computer account.

For low ambient light conditions the use of the dark display theme is recommended (see Figure 2).

Connect/disconnect the LabOne Data Server of the currently selected device. If a LabOne Data Server is connected only devices that are visible to that specific server are shown in the device list.



Indicates whether the LabOne User Interface is connected to the selected LabOne data server. Grey: no connection. Green: connected. Red: error while connecting.


Localhost Only

Forbid/Allow to connect to this Data Server from other computers.

File Upload

drop area

Drag and drop files in this box to upload files. Clicking on the box opens a file dialog for file upload.

Supported files: Settings (*.xml).

Session Id

integer number

Session identifier. A session is a connection between a client and LabOne Data Server.

Session Manager

btn uielements sessiondialog um

Open the session manager dialog. This allows for device or session change. The current session can be continued by pressing cancel.

File Name

selection of available file names

Save/load the device and user interface settings to/from the selected file on the internal flash drive. The setting files can be downloaded/uploaded using the Files tab.


Enable Save/Load of particular settings.

No Include Settings

Please enable settings type to be included during Save/Load.

Include Device

Enable Save/Load of Device settings.

Include UI

Enable Save/Load of User Interface settings.

Include UI and Device

Enable Save/Load of User Interface and Device settings.

Include Preferences

Enable loading of User Preferences from settings file.

Include UI, Device and Preferences

Enable Save/Load of User Interface, Device and User Preferences.


btn uielements save um

Save the user interface and device setting to a file.


btn uielements load um

Load the user interface and device setting from a file.


Choose the language for the tooltips.

Display Theme


Choose theme of the user interface.


Plot Print Theme


Choose theme for printing SVG plots.


Plot Grid


Select active grid setting for all SVG plots.



Plot Rendering

Select rendering hint about what tradeoffs to make as the browser renders SVG plots. The setting has impact on rendering speed and plot display for both displayed and saved plots.


Indicates that the browser shall make appropriate tradeoffs to balance speed, crisp edges and geometric precision, but with geometric precision given more importance than speed and crisp edges.

Optimize Speed

The browser shall emphasize rendering speed over geometric precision and crisp edges. This option will sometimes cause the browser to turn off shape anti-aliasing.

Crisp Edges

Indicates that the browser shall attempt to emphasize the contrast between clean edges of artwork over rendering speed and geometric precision. To achieve crisp edges, the user agent might turn off anti-aliasing for all lines and curves or possibly just for straight lines which are close to vertical or horizontal.

Geometric Precision

Indicates that the browser shall emphasize geometric precision over speed and crisp edges.

Resampling Method

Select the resampling interpolation method. Resampling corrects for sample misalignment in subsequent scope shots. This is important when using reduced sample rates with a time resolution below that of the trigger.


Linear interpolation


Piecewise Cubic Hermite Interpolating Polynomial

Show Shortcuts


Displays a list of keyboard and mouse wheel shortcuts for manipulating plots.

Dynamic Tabs


If enabled, sections inside the application tabs are collapsed automatically depending on the window width.

Graphical Mode


Select the display mode for the graphical elements. Auto format will select the format which fits best the current window width.



Log Format


Choose the command log format. See status bar and [User]\Documents\Zurich Instruments\LabOne\WebServer\Log




CSV Delimiter


Select which delimiter to insert for CSV files.



CSV Locale

Default locale. Dot for the decimal point and no digit grouping, e.g. 1005.07

Select the locale used for defining the decimal point and digit grouping symbols in numeric values in CSV files. The default locale uses dot for the decimal point and no digit grouping, e.g. 1005.07. The system locale uses the symbols set in the language and region settings of the computer.

System locale. Use the symbols set in the language and region settings of the computer

HDF5 Saving

Single file. All measurements go in one file

For HDF5 file format only: Select whether each measurement should be stored in a separate file, or whether all measurements should be saved in a single file.

Multiple files. Each measurement goes in a separate file

Auto Start


Skip session manager dialog at start-up if selected device is available.

In case of an error or disconnected device the session manager will be reactivated.

Update Reminder


Display a reminder on start-up if the LabOne software wasn’t updated in 180 days.

Update Check


Periodically check for new LabOne software over the internet.


Select the drive for data saving.



File format of recorded and saved data.


SXM (Nanonis)

Open Folder

Open recorded data in the system File Explorer.


path indicating file location

Folder containing the recorded data.

Save Interval

Time in seconds

Time between saves to disk. A shorter interval means less system memory consumption, but for certain file formats (e.g. MATLAB) many small files on disk. A longer interval means more system memory consumption, but for certain file formats (e.g. MATLAB) fewer, larger files on disk.


integer number

Number of data chunks not yet written to disk.


integer number

Accumulated size of saved data in the current session.



Start and stop saving data to disk as defined in the selection filter. Length of the files is determined by the Window Length setting in the Plotter tab.



Indicates whether data is currently written to disk.


filter or regular expression
