Navigation Buttons
Navigation buttons: There are two pairs of navigation buttons. The left and right exterior buttons go

sequentially, in the order they were captured, one at a time. The left/right arrows on the keyboard have
the same effect, as does pressing the Ctrl+N or Ctrl+P keys. The trigger number of the current event is

Event Classifications and Counts
Displays the classifications and number of each event type observed in the measurement. Clicking
on an event class will toggle the visibility of the associated events in the Risetime vs. Anode Energy
scatterplot and determine whether it will be skipped while scrolling. This is a convenient way to closely
inspect the traces in a certain event class without having to scroll through all the rest. All event classes
are initially toggled on. The event classes with a grey background aren’t displayed in the Risetime vs.
Anode Energy scatterplot plot because they don’t have a well-defined risetime, but they will be scrolled
through. The numbers and rates of events can be a useful diagnostic tool, for more information see
