Flashback Recall
Once a Notebook Entry is made, you can recall it at any time using Flashback Recall. The recall includes
waveforms and oscilloscope settings, so you can analyze the inputs that resulted in that capture.
1. Choose File > LabNotebook to open the LabNotebook dialog.
2. Select the Notebook and Notebook Entry from the lists.
3. Touch the Flashback Recall button.
4. To exit Flashback Recall, touch the Undo button at the far right of the menu bar.
Some result data not included in Flashback Recall are:
l
Persistence data - While it is saved in hardcopy and is printed on the report, it is not recalled during
Flashback.
l
Floating point waveforms - Certain math operations result in the creation of floating point wave-
forms with much higher resolution than can be stored in a 16-bit waveform file. This extra res-
olution is not preserved when traces are recalled using flashback.
l
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 wave-
forms, they lose their history and show instead only the results from the stored waveforms.
Customize Report
Teledyne LeCroy provides a default LabNotebook report template which includes our logo as a
placeholder. You can replace this with your custom logo. Logo files should be in bitmap (.bmp) format and
not exceed 100 pixels high by 180 pixels wide.
1. Copy the logo file to C:LeCroy\XStream\Xport folder.
2. Choose File > LabNotebook, then touch the Advanced tab.
3. Deselect the Use Default checkbox next to the Logo field.
4. Touch the Browse button and navigate to the the new logo file. Select and touch OK.The new file path
appears in the Logo field with a preview of the image above it.
