Flashback Recall
With a stored entry selected on the
My Notebook Entries
section of the
dialog, 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 the
Auto Trigger
front panel control.
PLEASE NOTE THE FOLLOWING
: The flashback feature currently recalls
the oscilloscope 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.
