Saving multi-channel signals
   SIGVIEW Help Home

Saving multi-channel signal can be performed by using Control Window.

First step is to find icons in Control Window corresponding to the channels of the signals you would like to save and selecting them in the right channel order. Next to the each selected icon, a selection order will be shown (1,2,...). It will correspond to the channel order in a saved file.

After selecting all channel in the right order, open context menu (right mouse button in the empty part of a Control Window).

The following options will be available if all selected signals are suitable for saving in one file (see below):

- Save selected signals as: Saves selected signals in a WAV file (16-bit integer or 32-bit float)

- Save visible part of selected signals as: Saves only a currently visible part of each selected signal in a file

- Export selected signals in ASCII/CSV file (X/Y values): Saves selected signals in an ASCII/CSV file including X/Y values. X-axis values from the first channel will be used.

- Export selected signals in ASCII/CSV file (Y values only): Saves selected signals in an ASCII/CSV file. Only signal amplitude values will be saved.


In order to save multiple channels in one file, all channels must have the same sampling rate (i.e. distance between samples). Furthermore, if the signals have different lengths, the longer ones will be saved only up to the length of the shortest one.
