Sequence mode is a fast acquisition mode that functions by dividing the instrument's acquisition memory into thousands of segments. Each of these memory segments stores a single acquisition, creating a single waveform of individual segments. Each segment is triggered, captured, and stored when a predetermined number of triggers is reached. Thus, sequence mode is ideal for capturing either fast pulses in quick succession, or events spaced over long periods.
Sequence mode enables fast trigger rates for capturing many fast pulses. It also optimizes memory usage by not capturing dead time (Figure 1). All triggers are time-stamped and displayed for the user's reference.
|Figure 2: Sequence mode is further enhanced by a number of|
display modes, such as perspective mode as seen here.
Sequence mode may be combined with complex triggers to isolate rare events. As a result, users can capture all instances over periods of hours or even days, viewing and/or analyzing each event at a later time. Further, there is a variety of ways in which the acquisitions can be viewed: adjacent (the default display mode), overlay, waterfall, perspective, and mosaic (Figure 2). Each of these views provides a different way to visually compare segments.
Not every measurement task involves acquisitions of lots of fast pulses or isolated events spread out over long periods of time. But when these sorts of measurements are called for, sequence mode is a great tool for capturing them in a way that's both useful and efficient.
