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

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