IRAMP

Type: CLASS

Purpose: The IRAMP class describes a current-ramp waveform that can be applied by a potentiostat while in the Galvanostat mode.

The Iramp object encapsulates information about the starting and ending currents, the ramp rate, and the data-acquisition rate. Most of the activity associated with the Iramp happens in the background while a Ciiv.Run() is being executed.

IRAMP uses a staircase waveform. Data are sampled at each level on the staircase.

The current range used for the IRAMP signal generator is selected from the largest absolute current specified by the ramp endpoints. The current range is fixed throughout the scan. The ramp generator does the best it can to reach the other endpoint using the current range in use. Generally the other endpoint current is only imprecise if it differs from the first by several orders of magnitude.
