VeriStand .NET API Reference

Setting Properties of DAQ Channels with the System Definition API

The following tables list properties of DAQ channels that you can set with the get/set property methods provided by the DAQChannel class, such as the SetDoubleProperty method. The table also lists the data type of each channel property, which determines the method to use to get or set the property. For example, use SetDoubleProperty to set channel properties whose data type is Double.

These measurement types and their properties correspond to properties you can manually configure for DAQ channels in the System Explorer window. Some properties, marked with "(Supported devices only)," are only available on certain devices. Refer to the documentation for your specific device to find out what properties your device supports.

Note Note  For detailed descriptions of channel properties, refer to the DAQ Device Channel Properties section of the NI VeriStand Help, available on the Contents tab at NI VeriStand Reference»DAQ Device Channel Properties.
