Browser=>Interpolation

This command creates a new NC file which contains one time channel. Data channels are interpolated for the selected time channel. The function cannot perform an extrapolation.

Example: A test contains data channels logged with 10 Hz and 100 Hz. Now you would like to execute some computations between channels of different time groups. In this case you can use this function to interpolate all data channel to a time channel with 100 Hz.

If the functions could be executed the result file will be displayed in the browser. The new file name is the name of the original file followed by the string _trans.

To execute the function open the data browser (File=>Import Data) and right click in the data grid. From the shortcut menu choose More Functions.

Time Channel List

The list displays all channels that possess the channel attribute Type="Time Channel". For MDF and IFILE files the attribute is created during the import. To create the attribute manually right click a time channel and choose Add Attribute from the shortcut menu.

Use Time Channel from File

Specifies whether a new time channel is created or a time channel from the list is used.

Channel Name

Name of the new time channel.

Unit

Unit of the new time channel.

Minimum

Minimum value of the time channel. The value should be in the measured time range. Values outside this range will be set to missing.

Maximum

Maximum value of the time channel. The value should be in the measured time range. Values outside this range will be set to missing.

Delta

Distance between two consecutive data points.

Comment

For MDF files (VS100/Inca) the channel name prefix Gxx_ is removed. Import of MDF Files.

The Browser=>Interpolation function is written in UniScript. The source code is found in the file mn_grid.ic.
