Configuring Analog Input Properties
After hardware channels are added to the analog input object, you should configure property values. As described in Configuring and Returning Properties, the Data Acquisition Toolbox supports two basic types of properties for analog input objects: common properties and channel properties. Common properties apply to all channels contained by the device object while channel properties apply to individual channels.
The properties you configure depend on your particular analog input application. For many common applications, there is a small group of properties related to the basic setup that you will typically use. These basic setup properties control the sampling rate, define the trigger type, and define the samples to be acquired per trigger. Analog input properties related to the basic setup are given below.
| Property Name |
Description |
SampleRate |
Specify the per-channel rate at which analog data is converted to digital data. |
SamplesPerTrigger |
Specify the number of samples to acquire for each channel group member for each trigger that occurs. |
TriggerType |
Specify the type of trigger to execute. |
