Crosspoint Detect - Crosspoint detect normalizes the data rising edge and falling edge histograms relative to the bit
clock (see Figure below). Pulsefind (Auto) sets the threshold automatically to the 50% level. Crosspoint detect
changes pulsefind to User Volts and automatically varies the threshold until the histograms of rising and falling
edges are overlaid.
Note: Above the 50% threshold, Falling edges precede Rising edge while below it, Rising edges precede falling
edges. This is equalizing the time delay between the bit clock and the data rising and data falling edges.
Cumulative Cycles (Adjacent Cycle) - Allows a measurement to be made over more than one consecutive period
Current Histogram Span - When the "Current Hist. Span" View is selected under "Curent View", the Histogram that
corresponds to the given span is shown. This selection enables the viewing of a select sampling of Histograms for
different spans (1 to 5, 10, 20, 50, 100, 200, and 250).
Current View - The Current View pull-down menu provides the user several different ways to see the acquired
measurement data, depending on the active tool.
Current View Diagnostic Tool - Opens the measurement tool that is currently being used for viewing the requested
measurements. Press "Current View Diagnostic Tool" from the view you are in to open that specific tool, make
the measurement and have control over a larger number of settings. If viewing the Oscilloscope view, Pressing
"Current View Diagnostic Tool" will open the Oscilloscope tool. You now have access to many more
configuration settings. If viewing the Histogram view, Pressing "Current View Diagnostic Tool" will open the
Histogram tool and allow different settings.
