20*a816646fSMarcelo SchmittDescription:
21*a816646fSMarcelo Schmitt		Number of frequency points (steps) in the frequency sweep.
22*a816646fSMarcelo Schmitt		This value, in conjunction with the
23*a816646fSMarcelo Schmitt		out_altvoltageY_frequency_start and the
24*a816646fSMarcelo Schmitt		out_altvoltageY_frequency_increment, determines the frequency
25*a816646fSMarcelo Schmitt		sweep range for the sweep operation.

32*a816646fSMarcelo Schmitt		Number of output excitation cycles (settling time cycles)
33*a816646fSMarcelo Schmitt		that are allowed to pass through the unknown impedance,
34*a816646fSMarcelo Schmitt		after each frequency increment, and before the ADC is triggered
35*a816646fSMarcelo Schmitt		to perform a conversion sequence of the response signal.
