  2. Date: March 2019
  3. KernelVersion: 3.1.0
  4. Contact: linux-iio@vger.kernel.org
  5. Description:
  6. Frequency sweep start frequency in Hz.
  7. What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_frequency_increment
  8. Date: March 2019
  9. KernelVersion: 3.1.0
  10. Contact: linux-iio@vger.kernel.org
  11. Description:
  12. Frequency increment in Hz (step size) between consecutive
  13. frequency points along the sweep.
  14. What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_frequency_points
  15. Date: March 2019
  16. KernelVersion: 3.1.0
  17. Contact: linux-iio@vger.kernel.org
  18. Description:
  19. Number of frequency points (steps) in the frequency sweep.
  20. This value, in conjunction with the
  21. out_altvoltageY_frequency_start and the
  22. out_altvoltageY_frequency_increment, determines the frequency
  23. sweep range for the sweep operation.
  24. What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_settling_cycles
  25. Date: March 2019
  26. KernelVersion: 3.1.0
  27. Contact: linux-iio@vger.kernel.org
  28. Description:
  29. Number of output excitation cycles (settling time cycles)
  30. that are allowed to pass through the unknown impedance,
  31. after each frequency increment, and before the ADC is triggered
  32. to perform a conversion sequence of the response signal.
