If the "Save capture to History" option is selected (default is off), each capture is stored on the Hard Drive as a history buffer and maintained according to the settings configured in Acquisition Options. Each project maintains its own history buffer in a sub folder using the same name as the project file. However, the project file does not require the history buffer to be present when opened. This allows the project file to operate as a 'stand-alone' file for sharing or archival purposes. When saving the project file, the currently loaded capture is embedded in the project (see also: Acquisition Options).
History Browsing
The history buffer can be accessed utilizing the History Menu, the Browse button or the bar graph. These items are located at the bottom of the main window. When browsing the history, the data for that history item will be loaded and all Signals, Auto Searches, Lists, Tables, etc. will refresh as if the data had just been captured.
