FDwfAnalogOutNodeFunctionInfo(
HDWF hdwf,
int idxChannel, AnalogOutNode node, int *pfsfunc)
Parameters:
- hdwf – Open interface handle on a device.
- idxChannel – Channel index.
- node – Node index.
- pfsfunc – Variable to receive the supported generator function options.
The function above returns the supported generator function options. They are returned (by reference) as a bit
field. This bit field can be parsed using the IsBitSet Macro. Individual bits are defined using the FUNC constants in
dwf.h. These are:
FUNC Constants FUNC Constant Capabilities
funcDC Generate DC value set as offset.
FuncSine Generate sine waveform.
funcSquare Generate square waveform.
funcTriangle Generate triangle waveform.
funcRampUp Generate a waveform with a ramp-up voltage at the beginning.
funcRampDown Generate a waveform with a ramp-down voltage at the end.
funcNoise Generate noise waveform from random samples.
funcCustom Generate waveform from custom repeated data.
funcPlay Generate waveform from custom data in stream play style.
FDwfAnalogOutNodeFunctionSet(
HDWF hdwf,
int idxChannel, AnalogOutNode node, FUNC func)
Parameters:
-
hdwf – Open interface handle on a device.
- idxChannel – Channel index.
- node – Node index.
- func – Generator function option to set.
The function above is used to set the generator output function for the specified instrument channel. With channel
index -1, each enabled Analog Out channel function will be configured to use the same, new option.
