Synchronizing Instruments

If several instruments Widget used for visualizing or editing data (e.g. oscilloscope or table). exist in a configuration Item that combines data from a data source, meta data (descriptions and comments) and visualization (layers, instruments, variable selection, property settings)., you can synchronize them. Instruments can be distinguished into instruments with variable scale and fixed scale. For more information, see Time Navigation and Synchronization.

Synchronization of different instrument types

If you want to synchronize these two different types of instruments with each other, the following recommendation applies: Start the synchronization from an instrument with variable scale. Then, the zooming level of each synchronized instrument with variable scale is adapted to this first instrument.

If you start the synchronization from an instrument with fixed scale, the current time stamp is used. All cursors in instruments with variable scale are deleted and one new synchronization cursor is created. The zooming level of each synchronized instrument with variable scale remains the same as before.

Synchronization time stamp

A synchronization time stamp indicates at which time stamp an instrument is synchronized with other instruments.

In the oscilloscope Instrument type for displaying graphically the course of signals over time., this time stamp is shown by a synchronization cursor Indicator used for marking the common time stamp when synchronizing different instruments. that automatically appears when synchronizing instruments. The active cursor within the visible range is used as synchronization cursor. If no cursor exists or the cursors are outside the visible range, a new cursor is created. The synchronization cursor cannot be deleted. In case the synchronization cursor is anchored, it remains always in the visible range and helps you to see the same point in time in e.g. a table or event list and the oscilloscope. If the synchronization cursor is not anchored, it is moved with the time line during scrolling or zooming. This means, it can be outside the currently visible time range. But the time stamp of the synchronization cursor is still used to synchronize with other instruments. If you stop synchronizing, the synchronization cursor remains in the oscilloscope. For more information, see To switch the synchronization cursor.

In instruments with fixed scale, the synchronization time stamp is highlighted in the second row in blue. If the synchronization time stamp is located between the first two rows, a blue line is displayed between these rows. You can move the synchronization time stamp to another row in the table. For more information, see To move the synchronization time stamp. When you stop the synchronization, the color of the highlighted row or line changes from blue to gray to indicate the current time of the time slider within the measure data.

To synchronize instruments

Click .

All instruments of the configuration are synchronized. Scrolling can be performed at any instrument in synchronized mode.
To stop the synchronization, click .

To Pause individual instruments

Click below the synchronization arrows.

A paused state is indicated by a red pause icon . And the synchronization symbol is shown in grey. In paused state the instrument is excluded from any synchronization activities. This means any changes of the time range or the cursors positions have no effect, neither from the paused instrument to the synchronization group nor vice versa. The paused state of an instrument is kept independently from whether the synchronization is active or not.
To end the paused state, click again the pause icon .
