Gwyscope hardware can be used to run different SPM feedback loop regimes, e.g. contact mode, tapping mode and to work with different types of probes. The main place to set it up is the hwserver and in particular its initialisation file hwserver.ini. As part of it, different scanning regimes are pre-configured, including parameters of the feedback loop (source of feedback, speed of feedback loop), internal connections on the electronics level and selection of input signals for the electronics. This is the primary place where the system should be set up.

Scanning regimes that can be operated from Gwyscope GUI mirror the scanning regimes on the hwserver. When user switches a particular measurement mode (Proportional, Tapping amplitude, Akiyama, etc.) the particular set of settings from hwserver.ini file is loaded, defining which inputs will be used, how the feedback loop will operate, etc. Details on particular predefined measurement modes are provided in other sections.
