Input Channel
Select the input channel or channels to the DataMode. The total number of input
channels for any DataMode is limited to 256. Use multiple DataModes for more than
256 input channels. All input channels to a single DataMode must have the same
sample rate and be defined for the same network node. For a summary of the data
types compatible with each DataMode, see
“Data Types” on page 191 .
Network Node
This field displays the defined network node for the DataMode.
Triggering Option
Select one of four available triggering options. Triggering provides a mechanism for
eliminating undesired segments of the input data stream before it is processed by any
particular DataMode algorithm.
Trigger Channel
Specify the trigger input when using a trigger option other than always on.
NOTE
The optional trigger channel must have the same sample rate as the set of input
channels to the DataMode.
Triggering Option Description
Always On Do not use triggering. Data sampling is always on from the start
of the test.
Trigger Data sampling starts when the trigger channel becomes TRUE.
Once the trigger channel is TRUE, data sampling runs
continuously, irrespective of any future changes in the trigger
channel.
Gate Data sampling occurs if and only if the trigger channel is TRUE.
Data sampling stops when the trigger channel is FALSE.
One Shot Take a single data sample when the trigger channel transitions
from FALSE to TRUE or if the trigger channel is TRUE on the first
sample of any run.
