What: /sys/bus/iio/devices/iio:deviceX/outY_freq_start KernelVersion: 3.1.0 Contact: linux-iio@vger.kernel.org Description: Frequency sweep start frequency in Hz. What: /sys/bus/iio/devices/iio:deviceX/outY_freq_increment 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/outY_freq_points 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 outY_freq_start and the outY_freq_increment, determines the frequency sweep range for the sweep operation. What: /sys/bus/iio/devices/iio:deviceX/outY_settling_cycles 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.
