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.
