+What:		/sys/bus/iio/devices/iio:deviceX/outY_freq_start
+KernelVersion:	3.1.0

+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.
