Adjusting the Horizontal Scale and Timebase Position
Use the Horizontal control to set the horizontal scale (time per division) and the
timebase (0 second) position and to magnify the waveform.
To adjust the horizontal scale and the timebase position, use the horizontal
control knobs or the Setting dialog box (Setting > Timebase). This dialog box is
opened by clicking the Setting icon on the sidebar or pressing the
Menu
key
located above the Horizontal control on the front panel.
Horizontal setup is shown in the Horizontal summary on the summary bar which is
located bottom of the screen. The summary shows the following information.
•
Horizontal scale (s/, seconds per division)
•
Horizontal center value (s, seconds), offset from the timebase
•
High resolution mode ON (HR) or OFF (no indicator)
•
Sampling rate (Sa/s, samples per second)
•
Number of samples (pts, points), memory depth
Clicking the Horizontal summary opens/closes the Timebase mini dialog box used

reference
Use the Timebase Reference slider on the Setting dialog box (Setting > Timebase).
The timebase reference position can be defined by percentage of the graph width.
50% defines it as the center of the time axis. This position is indicated by the
orange triangle at the bottom of the graph. See Figure 2-4 .
