Getting acquainted with your instrument
User interface elements
Each area of the user interface has a specific function that helps manage information or controls. This topic shows and describes the key
user interface elements.
1.
The Waveform Record View is a graphical high-level view of the overall waveform record length, how much of the record is on the
screen (shown in brackets), the location of key time events including the trigger event, and the current position of waveforms cursors.
If you are displaying a Reference waveform that is shorter than the current acquisition record length, or you are changing the
horizontal time scale while the oscilloscope acquisition is stopped, the brackets change position to show the part of the waveform
record that is being viewed relative to the current acquisition total record length.
If cursors are active on a waveform, the Waveform Record View shows the relative cursor positions as small vertical dashed lines.
When in Zoom mode, the Waveform Record View is replaced with the Zoom Overview. See
2.
The Expansion Point icon on the waveform view shows the center point around which the waveform expands and compresses when
changing horizontal settings.
3. The Trigger Position Indicator shows where the trigger event occurred in the waveform record. The trigger icon is displayed in the
waveform slice that is the trigger source.
