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.SetIchFilter(Freq)

Freq

The function argument Freq can be a REAL frequency. The filter is set so that frequency passes through the filter with less than 3 dB of attenuation.

Alternatively, Freq can be an INDEX, BOOLEAN, or a string constant that translates into an INDEX or BOOLEAN. See the tables below.

FilterSet

The return value FilterSet is an INDEX or a BOOLEAN. The tables above describe the return value. Note that the function does not return the REAL or string constant if one was used as the function’s argument.
