DAQmxCreateAOFuncGenChan
int32 DAQmxCreateAOFuncGenChan (TaskHandle taskHandle, const char physicalChannel[], const char nameToAssignToChannel[], int32 type, float64 frequency, float64 amplitude, float64 offset);
Purpose
Creates a channel for continually generating a waveform on the selected physical channel.
Parameters
| Input | |||||||||||||||||
| Name | Type | Description | |||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| taskHandle | TaskHandle | The task to which to add the channels that this function creates. | |||||||||||||||
| physicalChannel |
|
The names of the physical channels to use to create virtual channels. You can specify a list or range of physical channels. | |||||||||||||||
| nameToAssignToChannel |
|
The name(s) to assign to the created virtual channel(s). If you do not specify a name, NI-DAQmx uses the physical channel name as the virtual channel name. If you specify your own names for nameToAssignToChannel, you must use the names when you refer to these channels in other NI-DAQmx functions. If you create multiple virtual channels with one call to this function, you can specify a list of names separated by commas. If you provide fewer names than the number of virtual channels you create, NI-DAQmx automatically assigns names to the virtual channels. |
|||||||||||||||
| type | int32 | Specifies the kind of waveform to generate.
|
|||||||||||||||
| frequency | float64 | The frequency of the waveform to generate in hertz. | |||||||||||||||
| amplitude | float64 | The zero-to-peak amplitude of the waveform to generate in volts. Zero and negative values are valid. | |||||||||||||||
| offset | float64 | The voltage offset of the waveform to generate. |
Return Value
| Name | Type | Description |
|---|---|---|
| status | int32 | The error code returned by the function in the event of an error or warning. A value of 0 indicates success. A positive value indicates a warning. A negative value indicates an error. |
