Figure 1: Settings dialog - Oscilloscopes - Quick functions. (Click on a category to get more information.)
A number of quick functions is available in the Multi Channel oscilloscope software that simplify specific tasks related to oscilloscope channels. Some settings are available that determine on which channels the quick functions act.
By default, all channels up to the maximum number of channels are used for the quick functions. Channels that were not already used, are then turned on. When only use enabled channels is checked, only channels that are already enabled are used.
Maximum number of channels determines up to how many oscilloscope channels are used for a quick function.
