What: /sys/bus/iio/devices/.../out_altvoltageX_frequencyY
KernelVersion: 2.6.37
Contact: [email protected]
Description:
Stores frequency into tuning word Y.
There will be more than one out_altvoltageX_frequencyY file,
which allows for pin controlled FSK Frequency Shift Keying
(out_altvoltageX_pincontrol_frequency_en is active) or the user
can control the desired active tuning word by writing Y to the
out_altvoltageX_frequencysymbol file.
What: /sys/bus/iio/devices/.../out_altvoltageX_frequencyY_scale
KernelVersion: 2.6.37
Contact: [email protected]
Description:
Scale to be applied to out_altvoltageX_frequencyY in order to
obtain the desired value in Hz. If shared across all frequency
registers Y is not present. It is also possible X is not present
if shared across all channels.
What: /sys/bus/iio/devices/.../out_altvoltageX_frequencysymbol
KernelVersion: 2.6.37
Contact: [email protected]
Description:
Specifies the active output frequency tuning word. The value
corresponds to the Y in out_altvoltageX_frequencyY.
To exit this mode the user can write
out_altvoltageX_pincontrol_frequency_en or
out_altvoltageX_out_enable file.

KernelVersion: 2.6.37
Contact: [email protected]
Description:
Stores phase into Y.
There will be more than one out_altvoltageX_phaseY file, which
allows for pin controlled PSK Phase Shift Keying
(out_altvoltageX_pincontrol_phase_en is active) or the user can
control the desired phase Y which is added to the phase
accumulator output by writing Y to the phase_en file.
What: /sys/bus/iio/devices/.../out_altvoltageX_phaseY_scale
KernelVersion: 2.6.37
Contact: [email protected]
Description:
Scale to be applied to out_altvoltageX_phaseY in order to obtain
the desired value in rad. If shared across all phase registers
Y is not present. It is also possible X is not present if
shared across all channels.
What: /sys/bus/iio/devices/.../out_altvoltageX_phasesymbol
KernelVersion: 2.6.37
Contact: [email protected]
Description:
Specifies the active phase Y which is added to the phase
accumulator output. The value corresponds to the Y in
out_altvoltageX_phaseY. To exit this mode the user can write
out_altvoltageX_pincontrol_phase_en or disable file.
What: /sys/bus/iio/devices/.../out_altvoltageX_pincontrol_en
What: /sys/bus/iio/devices/.../out_altvoltageX_pincontrol_frequency_en
What: /sys/bus/iio/devices/.../out_altvoltageX_pincontrol_phase_en
KernelVersion: 2.6.37
Contact: [email protected]
Description:
out_altvoltageX_pincontrol_en: Both, the active frequency and
phase is controlled by the respective phase and frequency
control inputs. In case the device in features independent
controls, then there are dedicated files
(out_altvoltageX_pincontrol_frequency_en,
out_altvoltageX_pincontrol_phase_en).
What: /sys/bus/iio/devices/.../out_altvoltageX_out_enable
What: /sys/bus/iio/devices/.../out_altvoltageX_outY_enable
KernelVersion: 2.6.37
Contact: [email protected]
Description:
out_altvoltageX_outY_enable controls signal generation on
output Y of channel X. Y may be suppressed if all channels are
controlled together.
What: /sys/bus/iio/devices/.../out_altvoltageX_outY_wavetype
KernelVersion: 2.6.37
Contact: [email protected]
Description:
Specifies the output waveform.
(sine, triangle, ramp, square, ...)
For a list of available output waveform options read
available_output_modes.
