Setting Up Timing and Logging Properties for Waveform Acquisitions
Use tasks to define properties for when a system starts and stops acquisitions and how to perform data logging.
- Launch your project in the VeriStand Editor.
- In the Project Files pane, left-click a system definition file (.nivssdf) and select Configure in System Explorer.
- Click in the configuration tree.
- Under a DAQ device, click Analog Input.
- In the Sample Mode drop-down menu, select Waveform.
- In the Analog Input Task drop-down menu, select Create new...
- In the Create DAQ Task dialog box, name the task and set basic timing properties and click OK.
- Click Waveform Tasks and select the task you created.
-
Depending on your goal, access one of the following areas to configure how
VeriStand performs waveform acquisitions.
Goals Location Perform finite acquisitions and identify an external sample clock. Click the task and use the Task Configuration page. Allow logging and configure to save data in .tdms log files. Click Logging and use the Logging Configuration page. Control waveform acquisitions by DAQ devices. Use waveform task channels. Define triggers to for acquisitions to start and stop when a certain analog or digital value occurs or a software command is received. Click Triggers and use the Triggers Configuration page. - Save the system definition file.

Use DAQ devices to support analog, digital, and counter I/O functions such as acquiring waveform data.
- Adding Waveform Task Channels
Use Analog Input (AI) channels with waveform tasks to control waveform acquisitions by DAQ devices, such as how VeriStand logs waveform data and defines triggers that start and stop acquisitions.
- Single-Point Versus Waveform Acquisition
Specify if an Analog Input (AI) channel performs single-point or waveform acquisitions when you add the channel to a system definition.
