Tips
If “Save statistics to the acquisition file” is checked, the Continuous mode
cannot be used. The statistics are entered into a file at the end of the
duration period, so we must use the Fixed duration.
The file used for the statistics is the same as the file used for the
acquisition. Therefore, if the filename of the statistics is changed, the
acquisition log filename will be changed automatically.
To store only the statistics in a file, check the “Save statistics to the
acquisition file ” and start the statistics. To add statistics at the end of an
acquisition log file, check the “Save statistics to the acquisition file” option
and start the acquisition. The statistics will automatically start at the same
time and will be entered in the file at the end of the acquisition.
