SignalScope's MultiTool acts as a kind of project manager and host for the other tools in SignalScope. On iPhone, up to 2 other tools (subtools) may be added to the MultiTool at one time. iPad models support up to 4 subtools, except for iPad Pro models with 10.5-inch or larger displays, which support up to 6.
Besides the obvious benefit of being able to see and interact with multiple subtools, simultaneously, the MultiTool can save its current subtool configuration under a user-defined name. Any of the saved configurations can then be selected for immediate application in the MultiTool. This allows for different configurations to be saved for different projects or jobs. For example, one configuration might include an Oscope and FFT Analyzer and another might include an Octave Analyzer and a Data Recorder. On iPad, one configuration might include all 4. Even when using just a single subtool, the MultiTool allows multiple configurations of that tool (e.g. a unique configuration of the Dual FFT Analyzer for each of several different measurement types) to be saved and recalled at will.
As with other tools, data can be exported from within the MultiTool. In this case, all subtools that support data or image export (to data files or to a PDF, respectively) will export data to their respective file directories within the MutliTool's parent directory, using the file name specified.
