What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_frequency_start Date: March 2019 KernelVersion: 3.1.0 Contact: linux-iio@vger.kernel.org Description: Frequency sweep start frequency in Hz.

What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_frequency_increment Date: March 2019 KernelVersion: 3.1.0 Contact: linux-iio@vger.kernel.org Description: Frequency increment in Hz (step size) between consecutive frequency points along the sweep.

What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_frequency_points Date: March 2019 KernelVersion: 3.1.0 Contact: linux-iio@vger.kernel.org Description: Number of frequency points (steps) in the frequency sweep. This value, in conjunction with the out_altvoltageY_frequency_start and the out_altvoltageY_frequency_increment, determines the frequency sweep range for the sweep operation.

What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_settling_cycles Date: March 2019 KernelVersion: 3.1.0 Contact: linux-iio@vger.kernel.org Description: Number of output excitation cycles (settling time cycles) that are allowed to pass through the unknown impedance, after each frequency increment, and before the ADC is triggered to perform a conversion sequence of the response signal.
