|
|
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
|
|

|
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.
