Enumeration of the available impedance measurement modes.

class brainaccess.core.impedance_measurement_mode.ImpedanceMeasurementMode(*args, **kwds)[source]#

Bases: enum.Enum

Enumeration of the available impedance measurement modes.

Impedance measurement is used to assess the quality of the electrode-skin contact. Different modes use different frequencies for the measurement.

Impedance measurement is disabled.

Uses a 7.8 Hz wave for impedance measurement.

Uses a 31.2 Hz wave for impedance measurement.

Uses a wave with a frequency of sample_rate / 4 for impedance measurement.
