Class AnalogInput
Represents an operator that generates a sequence of voltage measurements from one or more DAQmx analog input channels.
AnalogInput
configures and starts a data acquisition task for sampling voltage measurements from one or more physical analog input channels. Samples from each channel will be collected in a sample buffer, where each row corresponds to a channel in the acquisition task, and each column to a sample from each of the channels. The order of the channels follows the order in which you specify the channels in the Channels
property.
If no input source is specified, data will be collected asynchronously every time a new buffer is filled.
Alternatively, if an input observable sequence is provided, a new data buffer will be collected every time a new notification is emitted by the input source.

Methods
| Improve this Doc View SourceGenerate()
Generates an observable sequence of voltage measurements from one or more DAQmx analog input channels.
Declaration
public override IObservable<Mat> Generate()
Returns
Type | Description |
---|---|
IObservable<Mat> | A sequence of 2D Mat objects storing the voltage samples. Each row corresponds to a channel in the acquisition task, and each column to a sample from each of the channels. The order of the channels follows the order in which you specify the channels in the Channels property. |
Overrides
Generate<TSource>(IObservable<TSource>)
Generates an observable sequence of voltage measurements from one or more DAQmx analog input channels, where each new buffer is emitted only when an observable sequence emits a notification.
Declaration
public IObservable<Mat> Generate<TSource>(IObservable<TSource> source)
Parameters
Type | Name | Description |
---|---|---|
IObservable<TSource> | source | The sequence containing the notifications used for emitting sample buffers. |
Returns
Type | Description |
---|---|
IObservable<Mat> | A sequence of 2D Mat objects storing the voltage samples. Each row corresponds to a channel in the acquisition task, and each column to a sample from each of the channels. The order of the channels follows the order in which you specify the channels in the Channels property. |
