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.
After initializing, the peak valley processing algorithm alternates searching for peaks and valleys based on the user-defined hysteresis. There are three states of the algorithm - initialize, peak search and valley search.
