FDwfAnalogOutNodeFunctionGet(
HDWF hdwf, int idxChannel, AnalogOutNode node, FUNC *pfunc)
Parameters:
- hdwf Open interface handle on a device.
- idxChannel Channel index.
- node Node index.
- ptrigsrc Pointer to variable to receive the generator function option.
The function above is used to retrieve the current generator function option for the specified instrument channel.
FDwfAnalogOutNodeFrequencyInfo(HDWF hdwf, int idxChannel, AnalogOutNode node,
double *phzMin, double *phzMax)
Parameters:
- hdwf Open interface handle on a device.
- idxChannel Zero based channel index.
- node Zero based node index.
- phzMin Variable to receive the supported minimum frequency.
- phzMax Variable to receive the supported maximum frequency.
The function above is used to return the supported frequency range for the instrument. The maximum value
shows the DAC frequency. The frequency of the generated waveform: repetition frequency for standard types and
custom data; DAC update for noise type; sample rate for play type.
FDwfAnalogOutNodeFrequencySet(
HDWF hdwf, int idxChannel, AnalogOutNode node, double hzFrequency)
Parameters:
- hdwf Open interface handle on a device.
- idxChannel Channel index.
- node Node index.
- hzFrequency Frequency value to set expressed in Hz.
The function above is used to set the frequency. With channel index -1, each enabled Analog Out channel
frequency will be configured to use the same, new option.
FDwfAnalogOutNodeFrequencyGet(
HDWF hdwf, int idxChannel, AnalogOutNode node, double *phzFrequency)
Parameters:
- hdwf Open interface handle on a device.
- idxChannel Channel index.
- node Node index.
- hzFrequency Pointer to variable to receive frequency value in Hz.
The function above is used to get the currently set frequency for the specified channel-node on the instrument.
