Data Browser Sample File Import

With the Sample File Import you can display samples from an external file in the Data Browser. For large number of samples (>100.000) there might be a delay for zoom, shift, … in the graph, because the Data Browser is designed to get data from an archive server. The Import action is available. The Sample File Import is not available in all CSS versions.

The Sample File Import action is available from the context menu (right click) in the Config View.

CSV Files

In the File Browser you can select the sample file for import. To distinguish between the different formats generated by the scopes the Sample File Import uses the file extension *.cvs-<scope-id>. The currently supported formats are:

ScopeExtension
Yokogawa DL750*.csv-yok
Tectronic*.csv-tec

Import Settings

After selecting the sample file the next dialog shows the channels in the file with the available information.

Choose the records to display

In this section is the list of all channels in the file with the name, start/end time of the measurement, number of samples that will be imported, total number of samples in the file, unit of the channel, formula to recalculate the samples. The fields name and unit are editable that you can change them for the import. The checkbox at the beginning of the row marks the channels that should be imported.

Time range for graph

The Start/End field shows the currently selected start and end time. If there is no active databrowser editor the default time is read from the sample file. If there is an active editor the default time is read from the time range in the graph. With the button 'Time' you can set the start/end time manually. The button 'from Graph' read the time range from the active editor and the button 'From File' from the sample file. The number of samples in the previous section will be automatically updated.

Factor

Especially for large files it is important to reduce the number of samples. For more than 100.000 samples the performance of the databrowser is slow. The Sample import will read each <factor> sample.

Time offset

Add a time offset to the time in the file. If you want to import channels from different scopes with asynchronous clocks you can adjust the file time to synchronise the samples.
