Pstat.SetVchFilter()

Type: INSTANCE FUNCTION

Purpose: Pstat.SetVchFilter() sets the filter on the voltage-measuring channel.

This filter has no effect on potentiostat stability.

If the parameter passed by SetVchFilter() 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. Use it exclusively for AC impedance measurements beyond 100 kHz.

Usage: FilterSet = Pstat.SetVchFilter(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.
