FDwfAnalogOutNodeSymmetrySet(HDWF hdwf, int idxChannel, AnalogOutNode node,

AnalogOutNode node, double percentageSymmetry)

Parameters:

- hdwf – Open interface handle on a device.

- idxChannel – Channel index.

- node – Node index.

- percentageSymmetry –Value of percentage of Symmetry (duty cycle).

The function above is used to set the symmetry (or duty cycle) for the specified channel-node on the instrument.

With channel index -1, each enabled Analog Out channel symmetry will be configured to use the same, new

option.

FDwfAnalogOutNodeSymmetryGet(

HDWF hdwf, int idxChannel, AnalogOutNode node, double *ppercentageSymmetry)

Parameters:

- hdwf – Open interface handle on a device.

- idxChannel – Channel index.

- node – Node index.

- ppercentageSymmetry –– Pointer to variable to receive value of Symmetry (duty cycle).

The function above is used to get the currently set symmetry (or duty cycle) for the specified channel-node of the

instrument.

FDwfAnalogOutNodePhaseInfo(HDWF hdwf, int idxChannel, AnalogOutNode node,

double *pdegreeMin, double *pdegreeMax)

Parameters:

- hdwf – Open interface handle on a device.

- idxChannel – Channel index.

- node – Node index.

- pdegreeMin – Minimum value of Phase (in degrees).

- pdegreeMax – Maximum value of Phase (in degrees).

The function above is used to retrieve the phase range (in degrees 0...360) for the specified channel-node of the

instrument.

FDwfAnalogOutNodePhaseSet(

HDWF hdwf, int idxChannel, AnalogOutNode node, double degreePhase)

Parameters:

- hdwf – Open interface handle on a device.

- idxChannel – Channel index.

- node – Node index.

- degreePhase – Value of Phase in degrees.

The function above is used to set the phase for the specified channel-node on the instrument. With channel index -

1, each enabled Analog Out channel phase will be configured to use the same, new option.
