7. Enable "Export history".
8. If you want to write the timestamps into the data file, enable "Time stamps".
9. To save one waveform out of the history memory:
a) Make sure that "Multiple acquisitions in one file" is disabled.
b) Enter the number of the required acquisition in "Acquistion index".
The newest acquisition in the memory always has the index "0". Older acquisi-
tions have a negative index.
c) Tap "Save" or "Save As" to save the waveform data to the specified file.
10. To save several subsequent history waveforms:
a) Enable "Multiple acquisitions in one file".
b) Define the range of the waveforms to be saved with "Start acquisition" and
"Stop acquisition".
c) Tap "Start export" to play the history and to save the history data to the speci-
fied file.

7.5 XY-diagram
XY-diagrams combine the voltage levels of two waveforms in one diagram. They use
the voltage level of a second waveform as the x-axis, rather than a time base. This
allows you to perform phase shift measurements, for example. You can display up to
four different XY-diagrams.
XY-diagrams can be used to display the IQ representation of a signal.
7.5.1 Settings for XY-diagrams
Access: [App Cockpit]>"Analysis" tab > "XY-Diagram"
You can display up to four different XY-diagrams that use the voltage level of a wave-
form as the x-axis, rather than a time base.
Make sure to select the tab of the required XY-diagram.
