Pstat.SetCASpeed()

Type: INSTANCE FUNCTION

Purpose: Pstat.SetCASpeed() sets the roll-off filter on the potentiostat control amp.

It can be varied from 0 to 3, with 0 being the fastest speed.

The control amplifier roll-off affects the overall stability of the potentiostat. As with the Pstat.SetStability() disclaimer, we can only offer you a general guideline in setting the CASpeed.

If the potentiostat oscillates on all current ranges, change the setting.

Four constants have been set to make code-reading easier. Located in the pstat.exp script, their names are:

CASpeedFast

CASpeedNorm

CASpeedMed

CASpeedSlow

Usage: SwitchSet = Pstat.SetCASpeed (Switch)


Switch	INDEX	Allowed values, with lower numbers being faster (hardware-dependent) 0–4 for PC5 0–3 for PCI4
	or
	REAL	Bandwidth required (Hz) Preferred!
SwitchSet	INDEX	The new setting.

Used with PC5 and PCI4 instruments.
