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.
