Peak Valley
The Peak Valley DataMode stores multiple channels of peak and valley sequences in the output data file. The system acquires peaks and valleys from triggered or un-triggered time history data streams using the user-defined hysteresis value and the peak-valley processing algorithm.

Common Parameters
- Name: Each DataMode must have a unique name and contain valid characters (invalid characters are single and double quotes, '\', '@', '#', '&', '<', '>').
- Description: Optional detailed description of the DataMode.
- Trigger mode: Select one of four available triggering options. Triggering provides a to eliminate undesired segments of the input data stream before it is processed by the DataMode.
- 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 and runs until the end of the data stream.
- Gate: Data sampling occurs if and only if the trigger channel is TRUE.
- 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.
- Trigger channel: Specify the trigger input when using a trigger option other than Always on. The trigger channel must have the same sample rate as the input channels.
- Channel select: From the channels list, select the desired input channels for the DataMode. Select channels either by dragging and dropping into the list on the right or by clicking the arrow buttons.
Specify the Hysteresis level for the peak-valley processing algorithm.
