Rearview - LeCroy LogicStudio Getting Started Manual

LogicStudio
The following screenshot shows a cursor pair placed on the waveforms display.

RearView

The RearView tool allows you to store and navigate through a history of data acquisitions retrieved from the
device(s). The expanded RearView tool's detailed control looks like the following:
RearView keeps a history of the last N acquisitions. View your stored acquisitions by setting your trigger to Stop
and using the slider on the detailed control to flip through the history. The currently selected acquisition is
shown in the waveform display area.
You can change the number of stored acquisitions by providing a new number in the text box at the right end of
the tool's detailed control.
The blue bar on the slider control displays how much of the RearView history is being used and available for
review. This bar fills up as you make new acquisitions until reaching your specified depth; at which point the
oldest acquisition is discarded when a new one is received.
Note: The RearView tool is always enabled. The default acquisition depth is set to 20 records.
The specific acquisition being viewed is always shown above the slider control – for example in the previous
screenshot the tool is showing acquisition 11 of 20 possible acquisitions. When you acquire a new acquisition
the RearView tool automatically adjusts to show the most recent acquisition.
TIPS:
• While using the RearView tool, you can modify your signal setup at any time and display additional
signals/data in different ways than how it may have been set at the time of the actual signal
acquisition.
• You can create a persistence display to compare acquisitions AFTER all the necessary acquisitions have
been obtained. Do this by enabling persistence mode, and then navigating through various
acquisitions available in the RearView tool. You can even generate a persistence display for a
timeframe or zoom level – even if the signal data was not yet visible at the time of acquisition.
