Peak Valley Matrix

The Peak Valley Matrix DataMode stores multiple channels of peak valley reversal histograms in the output data file. The CX23-R 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. The resulting peak valley stream defines the set of peak valley reversals which are histogrammed using the user-defined options for the type and size of histogram.

  • 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. Use triggering 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 and click the appropriate arrow. Alternatively, drag and drop the desired channels to the appropriate list.
