Pstat.SetIchFilter()

Type: INSTANCE FUNCTION

Purpose: Pstat.SetIchFilter() sets the two-pole Butterworth low-pass filter on the current-measuring channel.

This is a different filter than the I/E Filter described in the SetStability() section. It has no effect on potentiostat stability, only on the current-measuring circuit's frequency response.

If the parameter passed by SetIchFilter is a frequency in Hz, the potentiostat then selects the most appropriate filter setting able to pass information corresponding to this frequency.

NOTE: Do not use the No Filter setting (0) under normal circumstances. It is to be used exclusively for AC impedance measurements beyond 100 kHz.

Usage: FilterSet = Pstat.SetIchFilter(Freq)


Freq	REAL	Frequency of interest in Hz
	or
	INDEX	Filter to select: 0 = No Filter 1 = 200 kHz 2 = 1 kHz 3 = 5 Hz
	or
	BOOL	FALSE = Ground. No Pass Filter setting.
FilterSet	INDEX	The new filter setting.
