This setting is preferred when performing either: A) true four-terminal experiments (such as controlling the potential across an interface between two reference electrodes) or B) higher current experiments (> 100 mA). The Differential Feedback setting (PARSTAT® instruments only) sets the electrometer control circuitry to a true differential setting, where the potential is controlled between the Sense and Reference leads.

It is also the default setting (checkbox unmarked) for Override Auto E Feedback. Maximize Stability mode is less likely to cause oscillations so it is most often the preferred choice. This allows the potentiostat to be faster in applying a given potential, however it can cause oscillations with some cells. In Maximize Speed mode, the potentiostat has a higher bandwidth than Maximize Stability mode. Bandwidth is a measure of how quickly the control amplifier can 'keep up' with a rapidly changing applied potential without degrading the signal. These options affect how PowerSuite controls the power-amplifier feedback bandwidth during an experiment.
