Opening Trace Files
Opening a trace file saves you time as you do not need to perform your
acquisition again and can continue working where you left off.
To open a trace file:
1. From the Main Menu, Press File, and then press Open.
OR
From the main window, press .
2. If you had already acquired (but not saved) a trace, a warning window
appears, asking you if you want to save the current trace. Press Yes to
save the trace. Once the trace is saved, you can open a new trace.
Press No to display the new trace without saving the previously
acquired one. Press Cancel to return to the previous window.
3. Scroll through the list and select a trace to open.
4. Press Open to open the file. The trace appears in the Graph tab. All the
values in the main window except Markers tab will also be updated
from the file.
