This dialog box includes the following components:
WSN Configuration
| Property | Value/Description |
|---|---|
| Device Name | Specifies the name of the WSN node, which appears in the Project Explorer window. LabVIEW assigns a default name to the node based on the Hardware Configuration ID. You can use this field to give the node a descriptive name. |
| Device Type | Specifies the type of WSN node. You cannot change this value. |
| ID | Allows you to map a node in the property tree to a node of that ID on the gateway. |
Waveform Acquisition
| Property | Value/Description |
|---|---|
| Waveform Interval (Seconds) |
Waveform interval is time between successive waveform acquisitions, in seconds. The default value is 5.
Possible inputs are:
|
| Waveform Sample Rate (Hz) |
Waveform sample rate is the rate at which samples are taken within a single waveform. The default value is 10.
Possible inputs are:
|
| Samples to Read |
Samples to read is the number of samples within a given waveform. The default value is 10.
Possible inputs are:
|
|
The following diagram shows how these three properties work together:
For each sample, one sample is taken for each channel that is active. This means that the waveform shown in the diagram can be replicated up to 4 times, depending on which channels are enabled. These waveforms overlap in time, with a small offset between them (the settling time for each channel). |

Waveform Filtering
| Property | Value/Description | ||||
|---|---|---|---|---|---|
| Powerline Filtering |
When set to None, Powerline Filtering will average a series of ADC values to arrive at a single sample value. The time spent doing this can be set using the Aperture Time attribute. The default value is 50/60 Hz.
Possible inputs are:
|
||||
| Filtering Strength |
Sets or returns the filtering strength for the node. The default is High Rejection.
Possible inputs are:
|
||||
| Aperture Time |
Specifies the period during which the ADC is reading the input signal. The default value is 1.4 ms.
Possible inputs are:
|
