PLEASE NOTE THE FOLLOWING:

When an entry is first created and Report Title and Description
information is provided, your new entry is shown along with The Drawing
Toolbar at the top of the screen.

When finished and the Done button is touched from the Drawing Toolbar,
your new entry is shown on the My Notebook Entries list.
My Notebook Entries list shows the entries you've already stored on your
instrument. With a stored entry selected on the My Notebook Entries
section of the dialog.
With a notebook entry selected, you can touch the Flashback (Recall)
button to return your instrument to the state it was in when the Notebook
Entry was saved. Exit Flashback by touching the Undo Flashback button in
the top-right corner of the screen, or touch the Auto Trigger front panel
control.
PLEASE NOTE THE FOLLOWING:
The flashback feature currently recalls the DSO Setup, and all displayed
waveforms. Some of result data is not recalled, including:

Persistence data - While it is saved in hardcopy and is printed on the
report, it is not 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 is not
preserved when traces are recalled using flashback.

Cumulative Measurements - Any measurements 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 are recomputed using the
recalled waveform data. Normally, doesn't pose a problem; however, if
cumulative measurements were on when the entry was stored and the
cumulative measurements accumulated data from multiple acquired
waveforms, they lose their history and show instead only the results from
the stored waveforms.
