Recalling Notebook Entries
After a notebook entry is made, you can recall it at any time. The recall includes waveforms and
scope settings.
1. Select the notebook entry from the list box.
2. Touch Flashback.
3. To exit Flashback, touch the Undo Flashback button
in the top-right
corner of the screen, or press the Auto trigger button.
Note: The flashback feature currently recalls the DSO Setup, and all displayed waveforms. Some forms of ‘result data’ are
not recalled, including:
• Persistence data. This will be saved in the hardcopy, and will be printed in the report, but will not be recalled during
Flashback.
• Histogram data. Histograms internally have a 32-bit resolution, but when stored into a trace file and recalled during
flashback they are clipped to 16-bits.
• Floating point waveforms. Certain math operations result in the creation of floating point waveforms with much higher
resolution than can be stored in a 16-bit waveform file. This extra resolution will not be preserved when traces are
recalled using flashback.
• Cumulative Measurements. Any measurements that are on when the Lab Notebook entry is created are not saved
individually in the database, other than being embedded in the hardcopy image. This means that when flashback is
used, the measurements will be recomputed using the waveform data that was recalled. Normally this will not pose a
problem, but if cumulative measurements were on, which accumulated data from multiple acquired waveforms, they
will loose their history and show instead only the results from the stored waveforms.
