Data Acquisition Toolbox

Base Property Reference

This section provides descriptions of all toolbox base properties. Base properties apply to all supported hardware subsystems of a given type (analog input, analog output, etc.). For example, the SampleRate property is supported for all analog input subsystems regardless of the vendor.

In Properties Grouped by Category, the properties are summarized according to subsystem type and usage. In Properties Listed Alphabetically," the properties are described in detail.

Getting Command Line Property Help

To get command line property help, you should use the daqhelp function. For example, to get help for the SampleRate property

daqhelp SampleRate

Note    You can use daqhelp without creating a device object.

You can also get property characteristics, such as the default property value, using the propinfo function. For example, suppose you create the analog input object ai for a sound card and you want to find the default value for the SampleRate property.

ai = analoginput('winsound');
out = propinfo(ai,'SampleRate');
out.DefaultValue
ans =
        8000
